DRIVER 30 ALLOY is a copper-nickel alloy for use where low electrical resistance is required. The number designation corresponds to its specific resistivity (30 ohms/cir mil/ft) which is combined with a relatively high temperature coefficient of resistance. Its maximum recommended operating temperature is 600 F (316 C). This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-337. Producer or source: Wilbur B. Driver Company.
