摘要: A W—Cu—Ni alloy having thermophysical properties suitable for use in electrical contacts and electrodes is described. The formed by direct sintering of a powder blend comprising tungsten-copper composite nickel powder. component the comprises individual dual phase particles copper tungsten wherein substantially encapsulates phase. method eliminates formation brittle intermetallics slumping during sintering.
