Copper Tungsten Rod
Copper Tungsten Rod
Advantages
Copper Tungsten Rod combines the advantages of copper and tungsten, high strength, high specific gravity, arc ablation resistance, good electrical conductivity, good processing performance. High-purity tungsten powder and oxygen-free copper powder are used, and isostatic pressing (high temperature sintering-copper infiltration) is used to ensure product purity and accurate ratio, and its structure is fine. Good arc breaking performance, good electrical conductivity, good thermal conductivity and small thermal expansion
The alloy composed of tungsten and copper, the copper content of the commonly used alloy is 10% to 50%, and the tungsten copper is made of fine tungsten and copper powder, which is refined by a good soaking and sintering process, and can withstand high temperature and high stress of nearly 2000 degrees. High melting point, high hardness, anti-burning and good anti-adhesion, electro-erosion products have high surface finish, high precision and low loss.
Copper Tungsten Rod has a wide range of uses, mainly used to manufacture contacts of high-voltage electrical switches that are resistant to arc ablation, rocket nozzle throat linings, rudders and other high-temperature components, as well as electrodes for electrical processing, high-temperature molds and other high-temperature components. Occasions that require electrical and thermal conductivity and high temperature use.
