Nickel and Nickel Alloys Information | Engineering360
Nickel and nickel alloys are nonferrous metals with high strength and toughness, excellent corrosion resistance, and superior elevated temperature properties. Pure nickel is a bright silverwhite metallic element of the iron group and is hard, malleable, and ductile. Pure nickel itself is tough and corrosion resistant and provides an excellent base for developing specialized alloys.
