Ta-Cu Ta-Cu Method of Ta-Cu alloy for electric contact materials and Ta-Cu alloy for electric contact materials using the same

摘要

According to the present invention, a method for manufacturing a Ta-Cu-based alloy for an electrical contact member comprises: a step a) of preparing a mixture material by mixing 40-90 wt% of Ta powder and the remainder of Cu powder; and a step b) of carrying out solid-phase sintering on the mixture material, wherein the step a) performs mixing so that the Ta powder isn′t deformed and a shape thereof is maintained.
