Copper Tungsten has a wider range of uses

Copper Tungsten alloy composite material is a two-phase structure pseudo-alloy composed mainly of tungsten and copper, which is a metal-based composite material. Due to the large difference of the physical properties of copper and tungsten, it can not be produced by the casting method, Alloy technology for production.

Tungsten copper alloy has a wider range of uses, most of which are used in aerospace, aviation, electronics, power, metallurgy, machinery, sports equipment and other industries. Secondly, it should also be used to manufacture the contacts of the high-voltage electrical switches resistant to arc ablation and the rocket nozzle throat lining and tail rudder and other high-temperature components as well as the electrodes for electrical processing, high-temperature molds and other applications requiring electrical and thermal conductivity and high temperature occasion.

Tungsten comes from a kind of white sand type ore body. The ore line is particularly small. The tungsten ore powder with the grade above 95% is obtained through multi-channel processes such as digging, grinding, water re-election and refining etc., The finished product is tungsten. Tungsten gold melting point: 3500 ℃. Tungsten is currently mainly distributed in China and Russia, China is now the world’s largest tungsten exporter. Usually tungsten gold purity should be more than 99.95_, and must be issued by the authority of the test analysis and test reports.

Uses Unique tungsten has many unique uses, such as the high hardness of tungsten that can make tungsten steel. Made of tungsten steel tools, several times higher than the strength of ordinary steel tools and even dozens of times; with tungsten steel barrel, gun barrel, in a continuous shooting, even if the barrel is scalded by projectile hot, still maintain good flexibility And mechanical strength. In the metal cutting machine, with tungsten steel turning tool, the temperature can reach as high as 1000 ℃ still as before.

Spraying or surfacing stellite steels containing between 3% and 15% tungsten on common steel parts equals putting hard « armor » on the part, which is resistant to both temperature and pressure as well as to corrosion and corrosion resistance Wear and tear, the service life can be extended several times. Due to the superior properties and the wide range of uses of tungsten steel, 90% of tungsten produced annually in the world is used to make tungsten steel. Cobalt-Chromium Alloy plasticity.
