Nickel CAS 7440-02-0

Nickel is a hard, ductile and ferromagnetic metal that is highly polished and resistant to corrosion. Nickel is a ferrophilic element. The core is mainly composed of iron and nickel elements. In the crust, iron-mafic rocks contain more nickel than silico-alumina rocks. For example, peridotite contains 1,000 times more nickel than granite, and gabbro contains 80 times more nickel than granite. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer released the preliminary list of carcinogens for reference. Nickel compounds are in the list of carcinogens, metal cobalt, metal nickel and 66-67% nickel, 13-16% nickel. Chromium and 7% iron alloy powders for implantation of foreign bodies in vivo, nickel metal and nickel alloys are on the list of Class 2B carcinogens. Niclkel powder is mainly used in atomic energy industry, conductive materials, battery electrode materials, chemical catalysts, hard surface spray welding, special welding rods, porous filter materials, magnetic materials, contact materials, Diamond tools, automobile manufacturing, cemented carbide, high-temperature high-strength alloys and other powder metallurgy fields.
