Abstract
A new class of low chop contact materials based on Ag-chromium carbide and Ag--Cr compositions have an essentially 100% dense, porosity free microstructure. These materials combine the advantageous properties of Ag--WC and Cu--Cr contacts without their disadvantages. A method of making this new class of low chop contact materials includes the steps of cold pressing a mixture of Ag and chromium or chromium carbide to form an unsintered blank and the elevated temperature infiltration of silver into the unsintered blank to obtain an essentially 100% dense, porosity free microstructure.
