钨铜 CuW70 导电 导热性钨铜
Tungsten copper, tungsten and copper alloy, commonly used alloys of copper content is 10% ~ 50%. Preparing alloy by powder metallurgy method, has the very good conductive thermal conductivity, good high temperature strength and plasticity. At high temperatures, such as more than 3000 ℃, the copper alloy liquid evaporation, a large number of absorbing heat, reduce the material surface temperature. So this kind of material is also referred to as metal sweating. Tungsten copper alloy has a wide range of USES, mainly used in the manufacture of arc ablation resistance of high voltage electric switch contacts and rocket nozzle throat lining, tail rudder, such as high temperature component, is used for machining the electrode, high temperature requirement, as well as other conductive thermal conductivity and high temperature use. Tungsten copper choose fine tungsten and copper powder, the first-class soaked with sintering process refined but become, can withstand 2000 degrees high temperature and high stress, high melting point, high hardness, good burning resistance and the adhesion resistance, electric corrosion products high surface finish, high precision, low loss.
钨铜：钨和铜组成的合金，常用合金的含铜量为10%～50%。合金用粉末冶金方法制取，具有很好的导电导热性，较好的高温强度和一定的塑性。在很高的温度下，如3000℃以上，合金中的铜被液化蒸发，大量吸收热量，降低材料表面温度。所以这类材料也称为金属发汗材料。钨铜合金有较广泛的用途，主要是用来制造抗电弧烧蚀的高压电器开关的触头和火箭喷管喉衬、尾舵等高温构件，也用作电加工的电极、高温模具以及其他要求导电导热性能和高温使用的场合。钨铜选用精细钨、铜粉末，经一流浸透烧结工艺精制而成，可承受近2000度高温和高应力，具有高熔点、高硬度、抗烧损和良好抗粘附性，电蚀产品表面光洁度高，精度极高，损耗低。
