摘要： PROBLEM TO BE SOLVED: To lower the temp. coefficient of electric resistance from room temp. to a high temp. by working an alloy consisting essentially of chromium and gold into wire or sheet and heating the wire or sheet in a reducing or non- oxidizing atmosphere at a specified temp. SOLUTION: An alloy consisting of 0.1 to 30 atom % chromium and the balance gold with a small amt. of impurities is forged, cast, hot-worked or cold-worked into the wire, sheet, etc., of desired shape. The material is heated for 2 sec to 100 hr in a reducing or non-oxidizing atmosphere or vacuum at 200-1050 deg.C. As a result, a sensor alloy having deg.C average resistance temp. coefficient at 0-800 deg.C is obtained.
