Application of Tungsten Copper

Tungsten copper alloy is consisting of tungsten and copper, copper content of 10% to 50%. made of powder metallurgy alloy. It has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At high temperatures, such as above 3000 ℃. Tungsten copper alloy combines the advantages of tungsten and copper, which the high melting point of tungsten (tungsten melting point of 3410 ℃, coppermelting point 1080 ℃), Highdensity (density of tungsten 19.34g/cm, copper density 8.89/cm3); excellent thermal conductivity properties of copper, tungsten copper alloy (composition generally ranges WCu7 ~ WCu50) uniform micro structure,high temperature, high strength, resistance to arc erosion, density; conductivity,moderate thermal conductivity, high temperature materials are widely used in military, high-voltage switch with electrical alloy, EDM electrodes,microelectronics materials, parts and components are widely used as aerospace, aviation, electronic, electric power, metallurgy, machinery, sports equipment and other industries.

Tungsten Copper Alloy

Tungsten copper (copper tungsten, CuW, or WCu) alloy is a pseudo-alloyof tungsten and copper. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite than a true alloy.Copper Tungsten alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.

Tungsten Copper Alloy Main applications: For the spark erosion of dies of cemented carbide and for making high speed steel and switches and contacts in high and low voltage electrical devices.

Tungsten Copper materials

Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Only Tungsten Copper materials will stand these high temperature & aberration.

Tungsten Copper material has good resistance to arc erosion, mechanical wear, contact welding and good conductivity. They are usually selected for oil, gas, air or vacuum, devices. The contact surfaces will oxidize when switched in air. These press-sinter-infiltrate materials should only be considered for arcing surfaces in air when used as arcing tips, arc plates and arc runners. When switching with moderate contact arcing, the Tungsten Copper with a high copper content may give the lowest erosion. As arcing severity increases, the Tungsten Copper with the higher refractory content withstand arc erosion better. Tungsten Coppers are also used as arcing edges of selector switchblades in transformer tap changers.

Tungsten Copper Heat Sink

Tungsten copper heat sink is a composite of tungsten and copper. The coefficient of thermal expansion (CTE) of the composite can be designed by controlling the content of tungsten, matching that of the materials, such as Ceramics (Al2O3, BeO), Semiconductors (Si), Metals (Kovar), etc. The products are widely application in the fields such as radio frequency, microwave, high power diode packaging and optical communication system.

Advantages: High thermal conductivity, Excellent hermetic, Excellent size control, surface finish and flatness, Semi-finished or finished (Ni/Au plated) products available properties of WCu and MoCu heat materials.
