A History of Bronze Timeline

Detailing the History And Usage Of Bronze For Parts And More

Bronze is an alloy that consists mainly of copper and about 12% tin. Sometimes other metals like zinc, nickel, manganese, and aluminum are included. Some non-metal components like Arsenic are also added. The addition of different components results to the creation of different alloys which are sometimes harder than copper. The Bronze Age could be referred to as the period where Bronze was the hardest metal. This period can be dated back to as early as 4500 BC. You’ll be knowledgeable about the metal next time you visit a bronze parts machine shop. Bronze made it easier for people to make more durable metal objects which were previously impossible.

Bronze also formed a foundation for the transition to iron. This was after a disruption of the tin trade because of the population migrations. This resulted in fewer ships using the Mediterranean and passing through what is modern-day Britain. It was around the 2500 BC when Bronze was abundantly available and there were casting techniques that were advanced enough to create human statues. Even with the advent of iron and other metals, bronze still has several industrial applications that are useful.

Utilization Of Bronze Through The Ages


Bronze has been used to make jewelry for years and it is still relevant to date. When buying jewelry, you want it to last for the longest time possible. This is not always the case depending on the material that was used. Bronze is preferred for longevity because it is more durable than some metals.

Color possibilities: Bronze is used in making jewelry because of the wide range of color possibilities. Different elements can be included to give out a distinct color. For a yellow color, zinc is included while nickel is added to change the hue to white.

Detailing: Jewelry is about the fine details and bronze provides just about that. The casting process allows for the addition of texture, richness, and depth. Patina can also be added during the manufacturing process to create a vintage aesthetic.

Durable: Jewelry made from bronze are more likely to last longer because of casting materials. These materials provide extra durability and strength to the jewelry. You can use either silver or gold plating to provide visual aesthetics to the jewelry.

Springs, Bushings, and Bronze Bearings

Bronze bushings are strong and hard and tend to have a longer lifespan than brass bushings. The often require an external lubricant for them to work at the optimum level. When it comes to applications, bronze bearings are usually used in high-load and low-speed industrial machinery and applications. Bronze doesn’t produce sparks when struck against surfaces compared to steel. This makes it ideal to be used for huge hammers, or any other applications that may contain flammable vapors like those found in oil rigs.  

Bronze is also preferred when manufacturing musical instruments. It is always good to know about something you intend to use or use on a regular basis. Bronze as a metal has made significant contributions to human civilization and continues to be useful even today.

Choosing The Right Industrial Parts Material

The Difference Between Copper, Brass, And Bronze For Industrial Parts Usage

Bronze, copper, and brass can be a challenge to differentiate, especially when you don’t know what exactly to look for. Diversified Bronze & Manufacturing Inc. offers a wide variety of services with in-house machine capabilities to handle industrial services like mining and construction. If you are just starting out with metals, there are quite a couple of distinguishing features that separate the three major parts materials: brass, bronze, and copper. The whole process can be made simpler if you have a basic understanding of the different material components. Copper, brass, and bronze are all referred to as red metals, but feature a number of important differences when it comes to parts manufacturing.

Distinguishing Bronze Parts From Other Metals


Even though they are referred to as red metals, the three have different colors to them. You can identify copper with its rustic finish. Brass has a bright sheen with a brighter finish. Bronze has no sheen and has a darker finish to it.


Of all the three metals, copper remains true to its nature. It doesn’t consist of different metals. Brass consists of a mixture of zinc and copper. Varying the copper composition can lead to the production of different brass materials. Bronze, on the other hand, is a mixture of tin and copper forming the majority of the mixture.


When it comes to durability, copper is not only durable but also very flexible. It is almost impossible to crack when copper is in its purest form.  Bronze has almost the same level of toughness, but doesn’t offer a lot when it comes to flexibility. This can be good or bad depending on how you want to use the material. Brass is also strong although is not as durable as bronze or copper.


Copper is one of the most popular metals. This is because it can be used in several applications. One of the main reasons why it is popularly used is because of its thermal and electrical conductivity. It is a formidable metal and resistant to corrosion. One important aspect of copper is the ability to kill bacteria. A research conducted by the Environmental Protection Agency found out that copper could kill 99% of bacteria after two hours of contact. Copper has been in use since time immemorial. Early Greeks used it to make adornments and tools.


With brass, there are different compositions of zinc depending on the elements that have been included. There are different variations of colors depending on the mixture. An increase in the amount of zinc leads to more ductility and strength. The range in color from yellow to red depends on the amount of zinc that has been added. When it comes to applications, brass is mainly used for decorative and aesthetic purposes because it looks like gold.

Manufactured Bronze Parts

Bronze consists of mainly copper and other metals like manganese, aluminum, and phosphorus. The difference in the composition will lead to different properties. The easiest way to differentiate bronze from brass and bronze is the distinctive faint rings on its surface. Bronze is mainly used in medals, musical instruments, and sculptures. In industrial applications, it is also used in bearings and bushings.

Why Bronze?

It may surprise you to know, but here at Diversified Bronze & Manufacturing, Inc. (DBM), we work with more than just bronze. We’ve got a wide variety of materials at our disposal—from aluminum and brass to plastic and steel—to meet the varied needs of our customers. But there’s a reason we chose only one material—bronze—to include in the name of our company. Its resilience and versatility give it a profound utility across the wide range of industries we serve. If a customer needs the perfect part, there’s a good chance they need a bronze part.

Corrosion Resistance

Bronze is an alloy—a combination of multiple metals. Bronze alloy is composed primarily of copper, combined most of the time with tin. Both of these metals are non-ferrous, meaning they don’t contain iron. Why is that important? Because iron oxide is the main component in rust. Without iron, bronze doesn’t form rust when it comes into contact with oxygen. Instead, it actually forms something called “patina,” which creates a protective outer layer. Because of this, bronze is an excellent material for applications that involve exposure to moisture that contains oxygen.


Here at our facility in Braham, MN, we create custom parts for hydraulics, construction, marine, power, rail, oil and gas, boat dock, pump, cylinder, forestry, paving, and other industrial applications. That’s a lot of ground to cover, and a lot of industry-specific requirements. For many of the projects we work on, a custom machined part is the best choice. It allows our customers to design exactly what they have in mind, rather than trying to fit their design to an off-the-shelf part. Bronze parts have excellent machinability, giving us the freedom to create highly-specific parts that are tailored to the application at hand. Bronze is especially useful for jobs that require a great deal of complexity or intricacy.

High-Heat Resistance

Applications where extreme temperatures are present can make for some of the most challenging jobs here at DBM. Bronze is one of the best materials for these jobs thanks to its ability to effectively conduct heat and withstand high temperatures without distorting or expanding.

Resistance to Metal Fatigue

Over time and through consistent use, metal begins to weaken due to stress, with small cracks forming throughout. This is regular wear and tear, and necessitates the periodic refurbishment and replacement of metal parts. Of course, proper care and maintenance can prolong the life of any part, metal or otherwise. But starting with the right material is the key to creating parts and machinery that can withstand the test of time. Bronze resists metal fatigue even better than most steels.

Cost Effective

Here at DBM, our customers regard us as trusted bronze bearings and bronze bushings suppliers. Bushings and bearings are the parts that often wear out the quickest on machinery. By utilizing bronze for their bushings and bearings, our customers get a longer life out of these high-stress parts, saving significantly on the high cost of replacing machine shafts and housings. This makes bronze a cost-effective choice.

Product Spotlight: Cast Bronze Bearings

A lot of the technology we use today is relatively recent, popping up for the first time around the Industrial Revolution and then undergoing refinement and innovation until ending up where it is today. Cast bronze bearings, however, have been used in some form or another for hundreds of years.

Bronze bearings come in all sorts of shapes and sizes, including sleeve bearings, split bearings, flanged bearings, thrust washers, and wear plates. Custom oil grooves, threading, and drill holes are available on certain bronze bearings, as well.

The bottom line is that these are an essential part of many machines, and we just so happen to provide some truly excellent bronze bearings here at Diversified Bronze.

Choosing Cast Bronze Bearings

Knowing which cast bronze bearings to choose depends on the service conditions, the required material properties, and the type of bronze. While not all of these conditions can be known before buying these materials, an accurate prediction will be essential in purchasing the right bronze bearings.

Service Conditions

The first thing to consider when determining what bronze bearings may be necessary for a certain machine are the service conditions. According to, the following service conditions are the ones that can have the biggest impact on which bearings are the best fit:

  • Oscillating motion, especially those that fall short of full revolutions.
  • Environments that may prove corrosive to the metal.
  • Dirty environments, or environments that may require lubrication.
  • Inconsistent supplies of lubricants.
  • Temperature.
  • Machines that experience frequent stops and starts.
  • Shafts that can grow misaligned.

Knowing which of these environmental factors may affect your bearings can go a long way toward choosing the right ones.

Material Properties

The metals and other materials in machines also can affect which bronze bearings are most appropriate for a certain project. For example, we may look at any disparity between the hardness of the metals in use, as well as how that may impact the coefficient of friction between those two metals.

Other considerations include the material’s ability to absorb and discard small contaminant particles, its high compressive strength, its high fatigue strength, its corrosion resistance, its low shear strength, its structural uniformity and its cost and availability. Needless to say, we offer a number of bronze bearings that can work for each of these conditions.

Types of Bronze

The final consideration comes in the form of bronze types, of which there are many. Different alloys are better for all of the varying conditions listed above, with different metals helping to add certain qualities to the bronze. Tin bronzes, leaded tin bronzes, high-leaded tin bronzes, aluminum bronzes, and manganese bronzes all perform differently in action, giving each machine exactly what it needs to run as well as designed.

If a business needs any help determining what their needs are from their bronze bearings suppliers, we always are happy to help. At Diversified Bronze, we hold ourselves to a high standard in both service and product quality, especially when it comes to our cast bronze bearings.

Selecting The Best Bronze Bearings Materials: What You Need to Know

Bronze bearings are everywhere in machine design because they are, quite frankly, essential to keeping these machines from falling apart. Without them, the range of movement for certain mechanics would be way outside of the desired motion, increasing friction between various moving parts and wreaking all sorts of havoc on the machine itself. These bearings are absolutely necessary, and some type of bronze very often is the material of choice for manufacturing them.

Choosing a Bronze Bearing Material

It is not as easy as choosing bronze as a bearing material, however. Bronze bearings come in a number of different alloys to be used for different purposes. The following is a quick rundown of which alloys are best in certain circumstances:

Tin Bronzes

Adding tin to a bearing bronze alloy essentially serves the purpose of strengthening the metal. Tin bronzes are, as a result, very strong, but they also are hard and boast a high ductility, all of which makes them good for carrying heavier loads and holding up well over time, even in machines that really pound. They also perform especially well in seawater and brine.

Leaded Tin Bronzes

There are some tin bronzes that actually add a little bit of lead, which sounds as though it would add strength but in reality improves machinability, meaning it is easier to be cut and removed if needed at relatively low cost to the owner of the machine. Some leaded bronzes also contain some zinc, which is a way of strengthening the bearings more affordably than tin alone.

High-Leaded Tin Bronzes

There is significant demand for high-leaded tin bronzes because they are so versatile in a number of general applications at medium speeds and carrying medium loads. The strength and hardness of bronzes in this category are sacrificed a bit in favor of better anti-friction and machining properties, but all in all they are excellent bearings that work well in a number of circumstances.

Aluminum Bronzes

As the strongest of the bearing bronze alloys, aluminum bronzes are the only ones capable of being heat treated. That extra strength also allows them to deal with loads up to 50 percent higher than leaded tin alloys, meaning for heavier-duty jobs the aluminum bronze alloys are a smart, reasonable choice. They do come at the sacrifice of ductility and conformity, but for strength there’s no better option.

Manganese Bronzes

Perhaps the most complicated alloys in terms of makeup, the manganese bronze bearings feature zinc and small amounts of manganese, iron, aluminum and lead, all of which combine to create a bearing bronze that is strong, can operate at high speeds, can support heavy loads and can resist corrosion. They don’t deal with abrasion well, though, so the accompanying shafts need to be hard and relatively stationary.

Here at Diversified Bronze, we work with many of these different types of bronze bearings, and we are happy to answer any questions about which of these may be best for a certain type of machine. Simply reach out to us any time to ensure that your products maintain their integrity over time because of the high quality of bearing bronze used in the manufacturing process.

Common Modern Uses for Bronze

Since the Bronze Age, 3200 BC to 600 BC, humans have used this metal alloy to make metal tools that have lead to societal advancements. While the different formulas and uses of bronze have changed over time, its qualities continue to make it the perfect alloy for many tools, instruments and works of art. The purpose of this blog is to highlight some of the many uses of bronze today.

Bronze Bearings

The makeup of Bronze makes it great for creating bearings because of its increased strength and load bearing properties. Many times zinc, nickel or silver is often added to improve corrosion resistance, toughness and add to the life of the part. Bronze is also an ideal metal for machining into bronze bearings and bushings due to its malleability. Aluminum bronze often used for bearing due to its high strength and excellent shock resistance. It is important to pick the correct bronze alloy based on what it will be used for.

Spark Free Tools

Bronze has a special quality of not producing sparks. This is very helpful when it comes to working in flammable and explosive environments. Hammers, mallets, and other tools that produce friction are best made from bronze when working on oil rigs and other volatile work sites.

Coins, Medals and Sculptures

Getting third place in an Olympic completion is not the best in the World, but it will garner you a bronze medal. Pennies are often thought of as being made of copper, but are typically comprised of bronze. Bronze is commonly used in coins, medals and sculptures due to its ability to be molded, its strength and resistance to corrosion. Check out the bronze David made by Donatello to see an amazing work of art that has truly stood the test of time. Made in the 1440’s you can observe this statue today in Florence at the Bargello.

Musical Instruments

Bronze has long been used to create some of the most commonly used musical instruments. It is the preferred material for bells and cymbals used for centuries around the world. It is also used as components of the harpsichord, guitar and piano. Many of the Saxophones you hear at your favorite Jazz bar are made of phosphor bronze. The tambourine is another instrument commonly made out bronze due to its ability to reverberate a certain jingle.
