Abstract
An alloy for use as a fuse element in a high temperature fuse characterized by having a high resistance to corrosion and a melting point at a fixed temperature within a range of 1000.degree. to 1100.degree.C. The alloy consists of copper containing 10-14% aluminum and 0-2.5% of a second constituent which second constituent consists of one or more metals selected from a group consisting of nickel, manganese and iron. The alloy also has desirable hardness and good workability to enable fabrication of the alloy into a fused element.
Claims4
In a fuse having a pair of electrical terminals arranged in spaced relationship and insulated from each other, and a metal fuse element disposed adjacent the pair of terminals for forming the electrical connection therebetween, the improvement comprising the metal fuse element being of a metal alloy having a higher resistance to corrosion at elevated temperatures and a melting point at a fixed temperature within a range of 1000.degree. to 1100.degree. C, said alloy consisting of 10-14% aluminum, a second constituent in a range of 0-2.5% and the balance being copper, said second constituent consisting of at least one metal selected from a group consisting of nickel, manganese and iron.
