CR 155 is a silver-copper to which magnesium and phosphorus have been added to deoxidize the copper and give a precipitation-strengthening copper (alloy) having great strength and resistance to heat without an equipment loss in electrical conductivity. It is readily formable and can meet a large number of design requirements because it can be altered easily through cold working and heat treating (annealing) to develop a wide range of properties. Its many uses include electrical springs and contacts, radiator fins, tinsel wire in telecommunications and high-strength hook-up wire in aircraft. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-472. Producer or source: Copper Range Company.

Olin alloy 186 provides high thermal stability for elevated-temperature connector applications. This alloy provides exceptional resistance to loss in contact because of its excellent resistance to stress relaxation. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on forming. Filing Code: CU-635.
