Abstract
Abstract PURPOSE: To improve the plastic workability and melt sticking resistance of a contact material by internally oxidizing an Ag alloy obtd. by adding a specified amount of Sn and Bi to Ag. CONSTITUTION: To Ag are added 3W12 W/O Sn and 0.001W0.1 W/O Bi, and the resulting Ag alloy is internally oxidized in the form of fine grains and worked into the required form. The composite electrical contact material thus obtd. has superior plastic workability and melt sticking resistance. COPYRIGHT: (C)1981,JPO&Japio
