C18200 Chromium Copper - RWMA Class 2

MasterSource offers a complete line of Copper Alloy C18200 CrCu inventory as noted below.

Copper Alloy UNS C18200

A high conductivity chromium copper alloy that obtains its optimum properties from a combination of both heat treatment and cold work. Should be used in heat-treated condition.

This materials are stronger than Class 1 materials, have slightly lower conductivity. They are used for spot and seam welding of cold and hot rolled steel, stainless steel and low conductivity brass and bronze. They are also used as flash welding dies, and as electrodes for the welding of galvanized steel and other coated materials.

Chromium copper is the primary copper alloy used for resistance spot and seam welding. This alloy achieves good hardness and electrical conductivity though a combination of heat-treatment and cold work. C18200 is utilized for electrodes, holders, adaptors, as well as numerous electrical applications where resistance to deformation at high temperature is required or when higher mechanical properties than C11000 are required.
