ETP (Electro Tough Pitch Copper) is cast from the highest purity copper cathode available grade. Copper bar is used in various electrical applications and requires several key electrical and mechanical properties.

The chromium copper alloys are used for their high strength, corrosion resistance and electrical conductivity. They are used for spot and seam welding of cold and hot rolled steel, stainless steel and low conductivity brass and bronze.

Beryllium is a silver gray mettalic element that occurs naturally in about 30 minerals. It is lighter than Aluminum yet stiffer than steel. Beryllium gives Copper the strength of steel with the conductivity of a Copper Alloy.

This alloy meets the mechanical requirements of RWMA Class III Beryllium Copper without the using Beryllium. C180 Copper has very good mechanical strength along with moderate electrical and thermal conductivity.
