Copper bar is a kind of non-ferrous metal processing bar, with better processing performance, high conductivity.It is mainly divided into brass bars (copper-zinc alloy, cheaper) and copper bars (higher copper content) Brass bars are rods made of an alloy of copper and zinc. They get their name from their yellow color.Copper content of 56%~68% of brass, its melting point of 934~967 degrees.The mechanical and wear resistance of brass are very good, can be used in the manufacture of precision instruments, ship parts, gun casings and so on.
