C37700 brass consists of 59-62% copper, 0.5-1.5% lead, 0.05-0.7% tin, 0.03% iron, and the rest is zinc. The small addition of information enhances the machinability, while the container provides formability. C37700 brass can also be alloyed with small amounts of other elements, such as iron, manganese, and aluminium, to improve specific properties.It has good thermal and electrical conductivity, making it suitable for electrical and thermal applications.It has good flexibility and can be easily formed, bent, or stamped. Its elongation at break is around 30%. The addition of lead can decrease mechanical strength but improves machinability.C37700 brass is commonly used in plumbing fixtures, valve stems, gears, and decorative items. Its excellent machinability and formability make it perfect for products requiring intricate designs. It is also used in electrical applications such as connectors and switches because of its high conductivity and ability to withstand high temperatures.C37700 brass has a Brinell hardness of 100. However, adding lead can decrease the hardness and improve the machinability.
C37700 brass cannot be hardened by heat treatment. However, it can be annealed to improve its ductility and formability.C37700 brass can be welded using various methods, such as gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW). Preheating and post-weld heat treatment may be required depending on the method used.C37700 brass has good corrosion resistance in most environments.
