Tungsten Copper
We are a professional supplier of tungsten copper alloys. We own excellent facilities including hot rolling mills and four-high cold rolling mills. High quality tungsten copper alloys are produced from our factory by using high purity tungsten powder and oxygen-free copper. All our tungsten copper products have gone through the production process of sintering and infiltration.
Tungsten Copper
The quality of tungsten and copper alloy can be well controlled after perfect blending and accurate ratio. Tungsten copper alloy has the characteristics of high thermal stability, high arc resistance and high strength. It also has high conductivity and thermal conductivity. Our tungsten copper alloy conforms to GH 8320-87 standard of China.Our tungsten copper alloys are widely used in industrial fields such as aviation, kinetic energy, electric energy, metallurgy and machinery. Tungsten copper alloys can also be used for cooling equipment of electronic devices, components of feeding devices in aerospace vehicles etc.
