TUNGSTEN COPPER - COPPER ALLOYS

Marketech International, Inc. offers a wide variety of Tungsten products including Tungsten Copper and Copper Alloys.

 

Description of Tungsten-Copper Alloys

As high performance materials, Tungsten-Copper and Molybdenum-Copper are characterized by high thermal conductivity, low thermal expansion and high wear resistance combined with excellent electrical conductivity. These composites are made by infiltrating porous tungsten or molybdenum with molten copper in a vacuum. Thus, providing a direct copper path for heat or electrical conductivity.
