As acquaintance material, the blended is aggressive to abrasion by electric arc. Copper Tungsten is aswell acclimated in electrodes for electrical acquittal machining and electrochemical machining.

The admixture with beneath wt.% of chestnut has college density, college hardness, and college resistivity. The archetypal physique of CuW90, with 10% of copper, is 16.75 g/cm3 and 11.85 g/cm3 for CuW50 . CuW90 has college acerbity and resistivity of 260 HB kgf/mm2 and 6.5 μΩ.cm than CuW50.

These contacts are aswell acclimated in top accepted contactors area attrition to acquaintance adjustment and arc abrasion are required.The argent and tungsten carbide composites display antecedent attrition to accumulation of apparent films and acquire acceptable antiweld and arc abrasion resistance. These are distinctively acclimated for accessories acute added constant millivolt bead as analyze to argent tungsten.

Silver Tungsten abstracts fabricated by press-sinter-infiltration and commonly a top attrition to arc erosion. It is about acclimated as arcing contacts in ample air and oil ambit breakers.
