Tungsten Copper Alloy Plate Introduction:
Tungsten copper alloy plate is a composite material refined by the
process of static pressure forming, high temperature sintering and
copper infiltration by taking advantage of the excellent metal
properties of high-purity tungsten powder and the plasticity and
high conductivity of high-purity copper powder.
Tungsten copper alloy has the characteristics of small coefficient
of thermal expansion, no softening at high temperature, high
density, high hardness and high strength.
Tungsten Copper Alloy Plate Applications:
Tungsten copper alloy is widely used as electrical materials
(divided into electrical contact materials and electrical
processing materials), instantaneous high temperature materials and
military armor breaking materials. As an electrode, tungsten copper
alloy has the characteristics of low electrode material loss and
high material removal rate, which greatly improves the machining
accuracy and efficiency; As some instantaneous high-temperature
materials, tungsten copper alloy can use its own copper liquid
evaporation to take away part of the heat and ensure the normal
operation of the work.
When the tungsten copper alloy plate is used for the electrode of
the high-voltage discharge tube, when the high-voltage vacuum
discharge tube is working, the temperature of the contact material
will rise by thousands of degrees Celsius in a few tenths of a
second, while the ablation resistance, high toughness, good
conductivity and thermal conductivity of tungsten copper provide
necessary conditions for the stable operation of the discharge
tube.
