1. Military high temperature resistant materials
Copper Tungsten alloy is used in aerospace for missiles, rocket
engine nozzles, gas rudders, air rudders, and nose cones. The main
requirements are high temperature resistance (3000K~5000K) and high
temperature resistance to air erosion. Copper is mainly used at
high temperatures. The sweat cooling effect formed by
volatilization (the melting point of copper is 1083°C), reduces the
surface temperature of tungsten and copper, and ensures the use
under high temperature conditions.
2. Electrical alloy for high voltage switch
Copper Tungsten alloy is widely used in high-voltage switch 128kV
SF6 circuit breaker WCu/CuCr, and high-voltage vacuum load switch
(12kV 40.5KV 1000A), lightning arrester, high-voltage vacuum switch
is small in size, easy to maintain, and has a wide range of
applications. Use in flammable, explosive and corrosive
environments. The main performance requirements are arc ablation
resistance, fusion welding resistance, low cut-off current, low gas
content, and low thermionic emission capability. In addition to the
conventional macro performance requirements, porosity and
microstructure performance are also required. Therefore, special
processes are required, and complex processes such as vacuum
degassing and vacuum infiltration are required.
3, electrical machining electrode
Early EDM electrodes used copper or graphite electrodes, which were
cheap but not resistant to ablation. Now they have basically been
replaced by tungsten copper electrodes. The advantages of tungsten
copper electrode are high temperature resistance, high temperature
strength, arc ablation resistance, good electrical and thermal
conductivity, and fast heat dissipation. Applications are
concentrated in electric spark electrodes, resistance welding
electrodes and high-voltage discharge tube electrodes.
Electro-processing electrodes are characterized by a wide range of
varieties and specifications, small batches and large totals. The
tungsten copper material used as the electrode for
electro-processing should have the highest possible density and
uniformity of the structure, especially the elongated rod-shaped,
tubular and special-shaped electrodes.
4, microelectronic materials
Tungsten copper electronic packaging and heat sink materials have
both the low expansion characteristics of tungsten and the high
thermal conductivity of copper. The coefficient of thermal
expansion and thermal conductivity can be changed by adjusting the
composition of tungsten copper, thus providing better tungsten
copper. Wide range of applications. Because tungsten copper
material has high heat resistance and good thermal conductivity,
and at the same time, it has a thermal expansion coefficient that
matches with silicon wafers, gallium arsenide and ceramic
materials, so it is widely used in semiconductor materials. It is
suitable for high-power device packaging materials, heat sink
materials, heat dissipation components, ceramics and gallium
arsenide bases, etc.
