Semi-Finished Copper and Copper Alloy Products

Intro

WIRBALIT® Copper Alloys

Our proprietary copper alloys form the foundation for electrodes, current-carrying components, and wear-critical parts used in resistance and arc welding. They ensure low-loss electrical transmission, reliable heat dissipation, and maintain their shape even under mechanical stress.

WIRBALIT® materials are supplied either cold-worked or cold-worked and age-hardened, depending on the alloy type. Heating the materials beyond the specified softening temperatures significantly reduces their mechanical and physical properties.

Where thermal processes cannot be avoided, it is important to consider that for age-hardenable alloys, localized heating of asymmetrical parts may lead to cracking due to thermal stress. For this reason, machining or cold forming, such as extrusion or bending, should be the preferred processing methods.

Further information is available in our detailed processing guidelines.
