ABSTRACT:
The disclosed alloy has a temperature coefficient of electric resistance h an absolute value smaller than 100 ppm/.degree.C. in a temperature range between the order-disorder transformation point and melting point thereof, which alloy is made by molding an alloy consisting of 59.0-88.0 wt. % of palladium and the remainder of iron with a small amount of impurities, quenching the molded alloy from a temperature between the above-mentioned order-disorder transformation point and melting point to room temperature, cold working the quenched alloy for shaping, and annealing the shaped alloy.
