SILVER BASED SINTERED MATERIAL FOR ELECTRIC CONTACTS Russian patent published in 1995 - IPC

Abstract SU 1822591 A3

FIELD: powder metallurgy. SUBSTANCE: contact material comprises silver and 8 - 30 per cent of iron. It comprises 1 - 5 wt.% nickel, and 1 - 7 wt.% manganese oxide of MnO composition as alloying additions. Innovation is that the material along with silver, iron, and nickel has manganese oxide of MnO composition increasing wear resistance of contacts to switching. EFFECT: increased wear resistance to switching. 1 tbl
