NIMAG 120 is a commercially pure grade of nickel for electronic applications, especially for cathodes in electron receiving tubes. It is produced by vacuum melting to provide closely controlled composition. It is used where fairly easy activation is needed. 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, and joining. Filing Code: Ni-259. Producer or source: Spang Industries Inc..
