ELECTRICAL CONTACT MATERIAL CONSISTING OF A COBALT-NICKEL-IRON ALLOY AND METHOD FOR PRODUCING SAID MATERIAL

摘要

The invention relates to a material for electrical contacts, consisting of a martensitic cobalt-nickel-iron alloy with a high tensile strength, high flexibility and a high electric conductivity. The cobalt content of said material is 12.0 = Co = 60.0 wt %, the nickel content is 10.0 = Ni = 36.0 wt % and the remainder is made up of iron and an impurity content of less than 0.2 atomic percent, with a martensitic temperature Ms of 75 DEG C = Ms = 400 DEG C for the martensitic variant and 50 DEG C < Ms < 25 DEG C for the self-hardening cold-formed variant.
