C93200 High-Leaded Tin Bronze Alloy
A durable high-leaded tin bronze, C93200 is a cast alloy made up of copper, tin, and lead. It has good strength, wear resistance, and anti-friction properties. Because it resists corrosion well, it can be used in many different applications.
C93200 earned the name bearing bronze because its exceptional machinability has made it the alloy of choice in manufacturing bearings, bushings, and gears. Other applications include:
- Bronze High-pressure hydraulic equipment
- Bronze High-pressure steam equipment
- Bronze Nuts
- Bronze Piston rings
- Bronze Pump impellers
- Bronze Pump parts
- Bronze Structural castings
- Bronze Valve bodies
Diversified Bronze has solid and cored bronze bars in 144" lengths. Other lengths and non-standard sizes are available.
Technical details
C93200 is made up of 83% copper, 7% lead, 7% tin, and 3% zinc. The best welding techniques are brazing and soldering. We don't recommend using carbon arc, coated-metal arc, gas-shielded arc, or oxyacetylene.
