Brass is a copper alloy, and there are many kinds of brass, such as lead brass, tin brass, iron brass, manganese brass and so on. At the same time, all kinds of brass have different heat treatment states, such as: annealing state, surface hardening state, cold hardening state and so on. They have different mechanical properties and different hardness, the most common cast brass, for example, its hardness is Brinell hardness HB80~110, because the hardness is low, so can only be expressed by Brinell hardness, and Rockwell hardness HRC is suitable for quenched steel.
