Property Brief Introduction
W-Cu heat sink material is a composite of tungsten and copper, with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties, and the tungsten and copper in the thermal expansion coefficient and thermal conductivity can be adjusted with the W-Cu composition, also the composite can be machined to various shape, these features make the application of this composite with great convenience.
1) high melting point, high strength,
2) smooth and clean surface,
3) good conductions, small linear expansion coefficient and good heat-resistance

Pure tungsten rod Specification:
Surface:Black and polished
Purity:≥99.95%
Density:≥19.2g/cm3,
Surface roughness:<1.6
Dia:2.5-120mm
Pure tungsten rod surface finish:
Black: surface is as swaged or as drawn, retaining a ciating of processing lubricants and oxides.
Cleaned: Surface is chemically cleaned to removed all lubricants and oxides.
Ground: Surface is centerless to ground to remove all coating and to achieve precise diameter control.
