Abstract

A low electrical impedance contact element adapted to conduct current and designed to be able to operate in corrosive environments is made of a metal strip product. The metal strip product comprises a substrate (2) of steel with a tensile strength of at least 1000 MPa and on at least one side thereof coated by at least one coating layer (1, 3) of Ti or a Ti based alloy. Further, the invention relates to a method for producing a metal strip product according to electron beam evaporation. The steel substrate is etched by ion-beams before coating it. The contact element may be used in electrical devices, such as electrical switches, connectors and batteries, especially a spring element. The invention also relates to a coin cell battery, such as a Li/CFx battery.
