NICKEL 290 is a high-purity grade of nickel made by a powder-metallurgy process. Its high purity makes it useful for electronic applications such as components of hydrogen thyratrons and for battery applications. The low annealing temperature of Nickel 290 makes it superior to other forms of nickel as a substrate for precious-metal cladding. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-301. Producer or source: Huntington Alloys.
