Copper bars are generally used in air conditioning pipes, refrigerator pipes, oil pipes, water supply pipes and various mechanical supporting materials, automobile synchronizer gear rings, marine pumps, valves, structural parts, friction accessories, etc.

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.
