ELECTRODE MATERIAL FOR THERMAL FUSE AND PRODUCTION METHOD THEREFOR

摘要

The present invention relates to an electrode material for a thermal fuse that uses a cladding material formed by bonding two or more metal materials having differing properties and a production method for the electrode material. By using a wire comprising Cu or a Cu alloy as a base material, fitting a pipe comprising a Ag-Cu alloy and, as necessary, a pipe comprising a bonding layer to the base material, performing cladding and plastic working in order to achieve a multilayer clad wire or a multilayer clad material, and performing an internal oxidation treatment and plastic working on the result in order to configure a thin plate, the electrode material for a thermal fuse is configured so as to comprise a multilayer structure having an internally oxidized layer on the surface of both the front and rear surfaces of the thin plate and a Ag-Cu alloy layer or a Ag-Cu alloy layer alloy and a bonding layer that are formed on both the front and rear surfaces of a substrate layer.
