High Quality Tungsten-Copper Heat Sink Block

Tungsten copper alloy (W-Cu alloy) is the composite of tungsten and copper which own it excellent performance of tungsten and copper. It is used widely in such industries as engine , electric powder, electron, metallurgy, spaceflight and aviation.

Tungsten copper block are made from the fine tungsten and copper powder and used powder metallurgy technology.

Advantages of tungsten copper block are: 

high temperature resistance, 

high arc resistance, 

high strength and good thermal and electrical conductivity properties

Tungsten copper rod specification: 

thickness> =1mm

Length<=300mm

Length<=200mm

Tungsten copper block is an alloy that is made by pressing tungsten, sintering the pressed tungsten at a high temperature, and then infiltrating it with copper. Sintering is a metallurgic process by which a metallic powder is made into a coherent mass by heating without melting. The physical properties of both tungsten and copper make them not mutually soluble, meaning that one cannot be combined with the other, similar to the way oil and water will not mix. The alloy is made by dispersing the particles of one metal into a matrix or crystallized pattern of another. This makes tungsten copper's "micro-structure" or molecular shape that of a metal matrix composite and not of a true alloy.
