Copper tungsten carbide can be used as dies and anvils in electric heading. It is a refractory tungsten carbide-based composite material produced through pressing, sintering, and infiltration processes. Tungsten carbide content ranges from 50% to 70% by weight. Copper tungsten carbide is a strong material with good mechanical properties and is highly resistant to arc erosion in contact welding. Copper tungsten carbide is mainly used in petroleum installations to protect contacts from oxidation.

CuWC50 and CuWC56 composite materials have excellent resistance to mechanical wear and are mainly used for electrical contacts. CuWC50 has a higher copper content and conductivity and is used in heavy-duty contactors and transfer switches. CuWC56 is stronger and is used where high impact forces are likely to be encountered and higher wear resistance is required, such as arcing contacts in tap changers and oil interrupters.

Due to its high hardness and strength, CuWC70 is used in more severe electro-heading and electro-forging applications.
