This specification covers wrought gold-copper alloy in the form of wire, rod, strip, and tubing to be used for electrical contacts. Raw materials shall be of such quality and purity that the finished product (produced by cold working, heat treating, annealing, turning, grinding, and/or pickling as required) will have the properties and characteristics prescribed in this specification. The material shall meet the requirements of chemical composition specified for gold, copper, noble metal impurities, and other impurities. Ultimate tensile strength, elongation, microhardness (Knoop or Vickers), hardness (Rockwell or Rockwell Superficial), or a combination of these mechanical properties may be specified as the temper criterion. Annealed and hard drawn wires, strips, and tubings, within the prescribed diameter or thickness, shall conform to the specified tensile strength, elongation, and hardness. The following tests shall be performed: Knoop hardness test, tension test, chemical analysis such as spectrochemical or wet analysis, and stress corrosion crack test by immersion test, compression, and bending.
