The properties of copper bars produced by ordinary continuous casting copper bars can not reach the standard. The copper bars produced by extrusion process have good tensile strength, high hardness and high straightness. Generally, the amount of precision copper parts such as auto parts, medical parts and electrical accessories is relatively large.

Copper bar is a kind of non-ferrous metal processing bar, which has good processing performance and high conductivity. It is mainly divided into brass rod (copper zinc alloy, cheaper) and red copper rod (higher copper content).
