Product Description

Tungsten-Copper

Features

W-Cu

products of various specification and shapes with a wide range of copper content can be produced alternatively by press-sintering, direct infiltration, infiltrating copperinto high temperature sintered or activated sintered skeleton based on applications. The composites such produced are of high purity and homogeneous microstructure with superior performances as follows:

 

1. Excellent arc erosion resistant and anti-fusion ability.

2. Good electric and heat conductivity.

3. Low thermal expansion coefficient, matching with semiconductor, ceramics and Kovar alloys.

4. Easy matching.

5. Big gravity, high strength, high-temperature resistant and perspiration cooling characteristics.
