Abstract
The present invention relates to novel materials based on silver and tin oxide for the production of electrical contacts as well as the electrical contacts thus produced. According to the invention, these materials contain at least 6% by weight of tin oxide and from 0.02 to 5% by weight of tellurium oxide; the total content by weight of metal oxides, with the exclusion of tellurium oxide, does not exceed 15%, the balance being made up by silver. Application: manufacture of electrical equipment.
