Copper Beryllium C17200, RWMA Class 4, ASTM B196, AWS J1.3

 

Copper Beryllium is the highest strength copper alloy and is specified when the mechanical strength is the limiting design feature for a copper alloy. It is a heat treatable copper alloy having the unusual very combination of high hardness and strength and lower electrical conductivity than AWS J1.3/ RWMA Class 4 materials. Specify Cadi MOLD-MOR® 3 or 4 for mold applications.

 

Typical usages of RWMA Class 4 copper alloy: C17200 is recommended for flash and upset welding dies, projection welding and seam welding bushings, and other applications requiring harder copper alloys.
