Nickel and its Alloys

Nickel is obtained commercially from oxide ores, arsenical ores, and ores of Copper, Manganese and Iron, at least 85 percent of all nickel production is obtained from Sulphide ores. Pure nickel is tough silver-coloured metal, rather harder than Copper and have about the same strength, but possessing somewhat less ductility. It closely resembles Iron in several of its properties. It is malleable, weldable, and perceptibly magnetic. But unlike Iron, it is little affected by dilute acids. It is far less readily oxidisable, and deteriorates much less rapidly under atmospheric influences…
