Material Notes:

Description of Product: Tungsten-copper composite materials are produced by copper infiltration of porous sintered tungsten. They are available with different copper contents (10 - 30 %). A thermal conductivity over 200 W/m K is producible.Range of Application: Switching contacts for high-voltage and medium-voltage, heat sinks for passive thermal management, electrodes for erosive processing.Information provided by H.C. Starck.
