Abstract
An electrical contact comprising a matrix of an alloy of a high electro-conductive metal and a low melting point metal and particles of a refractory metal dispersed in the matrix. The electrical contact comprises the alloy containing a low melting point metal of at least one of Sn, Te and Be, and the refractory metal is Cr. The alloy comprising the low melting point metal in an amount of 0.5 to 3% by weight and the balance being Cu.
Claims1
A method of manufacturing an electrical contact comprising:
- mixing at least one of Tin (Sn), Tellurium (Te) and Bismuth (Bi), with Copper (Cu) and Chromium (Cr);
- melting the mixture at a temperature higher than the melting point of copper but lower than the melting point of chromium;
- solidifying the molten alloy;
- and
- shaping the molten alloy into a desired form.
