Another wrought alloy, C37700 forging brass, earned its name because it makes an excellent choice for forging. With exceptional hot-working characteristics, it can be easily shaped and has good machinability and moderate strength.
C37700 is used for builders' hardware and in the architectural, consumer, electrical, and industrial industries. Some common applications include:
Diversified Bronze has solid and cored bronze bars in 144" lengths. Other lengths and non-standard sizes are available.
C37700 is made up of 58-61% copper, 1.2-2.5% lead, and 0.3% iron. The best welding techniques include:
