Cu-Cr based electrical contact material, method of manufacturing the same, and electronic apparatus using Cu-Cr based electrical contact material

摘要

Disclosed are a Cu-Cr-based electrical contact material, a manufacturing method thereof, and an electronic device to which the Cu-Cr-based electrical contact material is applied. The disclosed method for producing a Cu-Cr-based electrical contact material includes the steps of preparing a cast material in a molten form including Cu and Cr as main constituent materials and Ti and Co as additives, Cu as cast from the cast material, Forming an alloy casting including Cr, Ti and Co and processing the alloy casting by a differential speed rolling process.
