Tungsten copper military block has low CTE, high soften temperature, which not only plays an important part in electrical materials, but also has been widely used in high temperature material and military armor material. The most outstanding characteristic is that copper evaporating takes away a part of heat and keep it working stable; in military field, for some missile, penetrator and liner, tungsten copper material remarkably improves armor capability.
Application
1. Used as EDM electrode, is easy for cutting and has sweat cooling, anti-adhesion, which is suitable for butt welding and projection welding with high requirement of wear resistance and high temperature resistance;
2. It can be widely used in high temperature material, electrical alloy for high-voltage switch, micro-electronics material;
3. Used in vacuum electrical contact, transformer switch contact and some electric upsetting electric forging industry and its good machinability processed into a variety of shapes of the W-Cu contacts as well as a variety of infiltration, casting material;
4. It provides a good solution for the deformation in small precision electrode machining;
5. Used as high temperature components of rocket, missile with high-speed airflow ablation, such as gas vane, nozzle, throat insert, nose con and so on;
6. In the 1990s, copper tungsten material has already begun used as new electronic package and the heat sink material. And it gradually appears in CPU, large-scale integrated circuit, high-power micro-wave device, connection and radiating component.
