An improved electrical contact alloy, useful for example, in vacuum interrupters used in vacuum contactors is provided. The contact alloy according to the disclosed concept comprises copper particles and chromium particles present in a ratio of copper to chromium of 2:3 to 20:1. The electrical contact alloy also comprises particles of a carbide, which reduces the weld break strength of the electrical contact alloy without reducing its interruption performance.
