Product Description

Product Description

TUNGSTEN COPPER ALLOY

Tungsten copper alloy is a composite metal of tungsten and copper, combining many excellent properties of metal tungsten and copper. Tungsten has a high melting point (tungsten melting point is 3410ºC, copper melting point is 1083ºC), high density (tungsten density is 19.30g/cm3, copper density is 8.92g/cm3); copper has excellent electrical and thermal conductivity. Tungsten copper alloy (composition generally ranges from WCu7 to WCu50) has uniform microstructure, high-temperature resistance, high strength, arc ablation resistance, and high density; moderate electrical and thermal conductivity, widely used in military high-temperature resistant materials, electrical alloys for high voltage switches, electrical machining electrodes, microelectronic materials, as parts and components are widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment and other industries.

HIGH-PERFORMANCE MATERIALS FOR AEROSPACE

Tungsten copper material has high density, sweat-cooling performance, high-temperature strength, and erosion resistance, and is suitable for aerospace materials with high-performance requirements.

ELECTRODES FOR EDM

When EDMing cemented carbide products, the special properties of cemented carbide make the copper or graphite electrodes lose very quickly, while the high electrical corrosion rate, low loss rate, precise electrode shape, and excellent processing performance of tungsten copper can ensure that the accuracy of the processed parts is greatly improved.

HIGH-VOLTAGE DISCHARGE TUBE ELECTRODES

When the high-voltage vacuum discharge tube is working, the temperature of the contact material will rise by several thousand degrees Celsius in a few tenths of a second. The high ablation resistance, high toughness, good electrical conductivity, and thermal conductivity of tungsten copper provide the necessary conditions for the stable operation of the discharge tube.

ELECTRONIC PACKAGING MATERIALS AND HEAT SINK MATERIALS

W-Cu electronic packaging materials have both the low expansion characteristics of tungsten and the high thermal conductivity of copper. Its thermal expansion coefficient and thermal conductivity can be designed by adjusting the composition of the material, which brings great convenience to the application of this material.

WIDELY USED

Suitable for materials packaged with high-power devices, such as substrates, electrodes, etc.; high-performance lead frames; thermal control plates and heat sinks for military and civilian thermal control devices, etc.
