Main features:

59-1 copper rod belongs to free cutting brass, which can be divided into environmental protection brass rod and ordinary brass rod. Generally, the genuine 59-1 copper bar is produced by extrusion process. The performance of the copper bar produced by ordinary continuous casting copper bar is not up to the standard. The copper bar produced by extrusion process has good tensile strength, high hardness and high straightness. Generally in auto parts, medical accessories, electrical accessories and other precision copper parts consumption is more.

Purpose:

Riveting 

Turning

Lathe processing

Hardware accessories
