2. Main Materials: CuW

3. General Description:

CuW contact materials have excellent resistsnce against arc erosion and anti-welding properties up to very high curret.CuW contacts are produced in a great variety of shapes by means of powder merallurgy(pressing/sintering or infiltration).The tungsten content is 50%-80%.

4. Application Scope

CuW contacts are mainly used in medium and high voltage switchgears. Typical applications are in high voltage circuit breakers, load switches,transformer switches tap changers and low voltage arcing contacts.

In addition, CuW materials are widely used as electrodes, primarily for welding.
