Wolfram-Copper Electrodes Description
Tungsten-based composite materials are high-melting metal materials. They are produced using strictly controlled processes comprising pressing, sintering and copper infiltration. The composite properties depend on the copper-to-tungsten ratio. A higher tungsten percentage provides increased resistance to arc erosion and wear, while thermal and electrical conductivities decrease.

Wolfram-Copper Electrode Applications
Wolfram-copper electrodes are utilised in a wide range of automated high-speed welding processes. For soldering copper and its alloys, these electrodes maintain a stable electrode temperature. This method is applied in high-speed spot welding of cable harnesses for motors, automotive sectors and other applications where cable assemblies are employed.
Packaging of Wolfram-Copper Electrodes
Wolfram-copper electrodes are clearly marked and labelled to ensure efficient external identification and quality control. Measures are taken to prevent damage during storage or transportation.
