Nickel 270 is a high purity nickel exceptionally free from non-metallic inclusions. Its low hardness and good ductility permit heavy cold deformation without reannealing. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-143.
