ABSTRACT:
Electrical contacts are formed from a silver-iron material which contains 3 to 30% by weight of iron and one or more of the components manganese, copper, zinc, antimony, bismuth oxide, molybdenum oxide, tungsten oxide or chromium nitride in amount totalling 0.05 to 5 weight percent, the balance being silver. These materials are suitable for forming electrical contacts of a wide variety. Tantalum is an optional component which may also be utilized particularly when 0.2 percent to 2 percent zinc is present.
