MONEL is a general purpose nickel-copper alloy having excellent combination of high strength, ductility and corrosion resistance. Cold-worked, welded and cast forms behave substantially the same under corrosive conditions. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-21.
