<P>PROBLEM TO BE SOLVED: To provide a contact material that can be easily welded and removed, and to provide a method for manufacturing the same. <P>SOLUTION: In the contact material is formed of Cu, Cr and Te, Cr particles, Cu-Cr-Te particles in which a Te-Cu-Cr phase and a Cu-Te phase are mixed, and Cr-Te particles are dispersed in a base material mainly consisting of Cu, a Te-containing phase is formed in particle boundaries between the base material and the Cr particles, a Cr content is 40-50 mass%, a Te content is 0.1-2.0 mass%, and the rest is Cu. The manufacturing method includes filling the mixed powder in a sintering mold, and applying pulse energization pressure sintering thereto at a temperature of 700-1,080°C under a pressure of 30-200 MPa. <P>COPYRIGHT: (C)2013,JPO&INPIT |
