Abstract

This paper introduces the technology of activating CuCr50 alloy powder by MA(Mechanical Alloying) and sintering CuCr50 powder by SPS(Spark Plasma Sintering). It analyzes the effect on electrical conductivity and hardness of CuCr50 alloy when Cu powder in different morphology. The results indicate that the CuCr50 powder sintered by SPS takes a good sintering shape, whose electrical conductivity and hardness get improved. At the same time, CuCr50 alloy density has been improved. The flake morphology Cu powder improves the electrical conductivity of 32.7% than the pine morphology needle Cu powder. And the bigger flake Cu powder is, the better CuCr50 alloy electrical conductivity is. CuCr contact material has excellent mechanical and electrical properties and is widely used in vacuum switchgear[1]. As contact materials, CuCr50 alloy can play such an important role in the actual production and application.Improving the mechanical properties and electrical performance are the main trend for development of high performance CuCr alloy.
