Silver-iron material for electrical switching contacts (II)

摘要

Silver-iron materials for electrical switching contacts with properties which come very close to those of silver-nickel materials formed of 4.6 to 15% by weight iron and 0.05 to 5% by weight of one or more of the oxides magnesium oxide, calcium oxide, yttrium oxide, lanthanum oxide, cerium oxide, chromium oxide, iron oxide, aluminum oxide, indium oxide, silicon oxide, and tin oxide, the balance being silver.
