Material Introduction
Tungsten Copper
Material Introduction
Tungsten-copper alloys are composed of tungsten and copper. The copper content in commonly used alloys lies between 7% and 50%. Combining the advantages of both tungsten and copper, they can be used in military materials, high-voltage switching materials, electrical machining electrode materials and microelectronic packaging materials; they are widely widely used as parts and components in machinery, electric power, electronics, metallurgy, aerospace and other industries.
We produce tungsten-copper alloy materials to any ratio, and obtain the required material properties by adjusting the ratios of tungsten and copper.

Fabrication Process
Advantage
Due to the incompatibility of tungsten and copper, the tungsten-copper alloy features the low expansion, high wear resistance, and high corrosion resistance of tungsten, along with the high electrical and thermal conductivity of copper. It is thus suitable for various forms of mechanical processing. Therefore, the tungsten copper alloy is widely used for its high strength, high specific gravity, high temperature resistance, arc ablation resistance, good electrical conductivity, good processing performance, good arc breaking performance, good electrical conductivity, good thermal conductivity, small thermal expansion and perspiration cooling.
