The first thing that comes to mind when we think of brass rods is leaded brass rods, and leaded brass rods are actually the most widely used form of lead brass.

The lead content of leaded brass is less than 3%, in addition to a small amount of Fe, Ni or Sn, its alloy composition can contain various alloy elements, and the content requirement is relatively loose, which makes a great contribution to the comprehensive utilization of copper alloy raw materials. It is a widely used lead brass, with good machinability, good mechanical properties, can withstand cold and hot pressure processing, easy fiber welding and welding, and has good stability to general corrosion, but has the tendency of corrosion cracking. Hot working temperature 640 ~ 780℃; Annealing temperature 600 ~ 650℃; The low temperature annealing temperature to eliminate internal stress is 285℃.

Pb exists in the structure of leaded brass in a free state, which splits the matrix and makes the leaded brass have good machinability, antifriction and high strength.
Mainly used in mechanical engineering all kinds of connectors, valve stem bearings, especially hot forging valve blank, lock industry, watch industry is the three important markets of lead brass.
