Copper Tungsten Plate Wcu Alloy Sheet is an alloy composed of tungsten and copper. Commonly used alloys contain 10% to 50% copper. The alloy is prepared by powder metallurgy, which has good electrical and thermal conductivity, good high-temperature strength and certain plasticity. At very high temperatures, such as above 3000°C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat, and reducing the surface temperature of the material. So this kind of material is also called metal sweating material.
Since the two metals of tungsten and copper are incompatible with each other, tungsten-copper alloy has the low expansion, wear resistance, corrosion resistance of tungsten and the high electrical and thermal conductivity of copper, and it is suitable for various mechanical processing. Tungsten-copper alloys can be produced according to user requirements for tungsten-copper ratio production and size processing. Tungsten-copper alloys generally use powder metallurgy processes to prepare powder-batch mix-press molding-sintering infiltration.
Tungsten-copper composite material is a two-phase structure pseudo-alloy mainly composed of tungsten and copper elements. It is a metal-based composite material. Due to the large difference in physical properties between metallic copper and tungsten, it cannot be produced by melting and casting. Generally, powder alloys are used. Technology for production.
Tungsten-copper alloy has a wide range of uses, most of which are used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries. Secondly, it is also used to manufacture high-temperature components such as the contacts of high-voltage electrical switches that are resistant to arc ablation, rocket nozzle throat linings, and tail rudders, as well as electrodes for electrical machining, high-temperature molds, and other applications that require electrical and thermal conductivity and high-temperature use. occasion.
Copper Tungsten Plate picture:
The process of preparing tungsten-copper alloy by powder metallurgy is powder-making-batching mixing-pressing forming-sintering infiltration-cold working.
Tungsten-copper or molybdenum-copper mixed powder is press-formed and then sintered in liquid phase at 1300-1500°. The material prepared by this method has poor uniformity and many closed voids. The density is usually less than 98%. However, ultra-fine and nano-powders are prepared by the activation sintering method with a small amount of nickel, mechanical alloying method or oxide supply reduction method It can improve the sintering activity, thereby increasing the density of tungsten-copper and molybdenum-copper alloys. However, nickel activation sintering will significantly reduce the electrical and thermal conductivity of the material, and the introduction of impurities in mechanical alloying will also reduce the conductivity of the material; the oxide co-reduction method to prepare powders is cumbersome in the process, low in production efficiency, and difficult to mass production.
