This standard addresses common copper alloy and composite materials employed in the manufacture of resistance welding electrodes, resistance welding dies, and related components such as adapters, holders, and structural components of the welding circuit.

This standard addresses bar, rod (straight lengths and coils), plate, and casting forms of select materials. The standard does not address material in sheet form.

The standard does not include all copper and copper base materials that may be applied in the construction of resistance welding machines or tooling. Examples of materials not currently covered are: electrolytic tough pitch (ETP) copper, brass, and bronze.

Unique, specialized, and new materials exist in domestic and international marketplaces and their absence here should not be interpreted as a commentary on their suitability for a particular application.
