Abstract
A material for electrical contacts comprising a martensitic cobalt-nickel-iron alloy with a high strength, a high bendability and a high electrical conductivity, with a cobalt content of 12.0≦Co≦60.0% by weight, a nickel content of 10.0≦Ni≦36.0% by weight, remainder iron and an impurity content of less than 0.2 atomic percent, with a martensite temperature Ms of 75° C.≦Ms≦400° C. in the case of the martensitic variant and −50° C.≦Ms≦25° C. in the case of the variant which is naturally hard as a result of cold-forming.
