7.Applications:
Tungsten copper disks combines the advantages of tungsten and copper, which with high melting point of tungsten
(tungsten melting point of 3410 ℃, copper melting point 1080 ℃), high density (tungsten density of 19.25g / cm,
copper density of 8.92 / cm3) ; excellent thermal conductivity properties of copper, tungsten copper alloy (composition
generally ranges WCu7 ~ WCu50) uniform microstructure, high temperature, high strength, resistance to arc erosion,
high density; moderate conductivity, thermal conductivity, high-temperature materials are widely used in military ,
high pressure switch with electrical alloy, EDM electrode, microelectronic materials, parts and components as widely used
in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment and other industries.
Military High Temperature Materials
Tungsten copper alloy sheet is used as missiles in aerospace, the rocket engine nozzle, gas rudder, air rudder, the nose,
the main requirement is to require high temperature (3000K ~ 5000K), high temperature air erosion capacity, the main use
of copper at high temperatures sweating under refrigeration volatile form of (copper melting point of 1083 ℃), reducing
the surface temperature of tungsten copper, ensure that the use in extreme conditions at high temperatures.
