Copper tungsten materials,Copper Tungsten Electrical Contacts,WCu Electrode material

Tungsten copper alloy is an alloy of tungsten and copper. Commonly used copper content of the alloy is 10% to 50%. Preparation of alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, the alloy of copper is liquefied and evaporated to absorb a lot of heat, reducing the surface temperature. So this kind of material is also referred to as metal sweat material.

Copper tungsten composite material

Copper Tungsten alloy composite material is made of tungsten and copper are two mutually false solution alloy metal, which combines the high electrical conductivity of tungsten melting point, high hardness, low coefficient of expansion and copper. Is a very good performance composites. Copper Tungsten alloy Material not only has good thermal conductivity and low coefficient of thermal expansion, but also by changing the content of tungsten to the design of its thermal conductivity and expansion coefficient, these features make the tungsten-copper composite material in high temperature, high pressure switch with electrical alloy , EDM electrode, microelectronic materials, as parts and components.
