2. Property Brief Introduction
Tungsten Copper Alloy Of Bar/Rod 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
