This specification covers 69% gold, 25% silver, 6% platinum alloy tubing, rod, wire, and sheet material for sliding electrical contacts. The material shall be finished by such operations (cold working, annealing, turning, grinding, pickling) as are required to produce the prescribed properties. The material shall be tested and conform to chemical composition, and mechanical and electrical property requirements. The mechanical requirements of the material are ultimate tensile strength, elongation, microhardness, hardness, or a combination of these mechanical properties as temper criterion. All tests shall be conducted at room temperature.
