Nickel Properties




Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt. Historically it has been used for plating metals such as iron and brass, for chemical apparatus, and in certain alloys such as German silver. It is still used for corrosion-resistant pure-nickel plating. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation. Enzymes of some microorganisms and plants contain nickel as an active center, which makes the metal an essential nutrient for them. It is used in many industrial and consumer products, including stainless steel, magnets, coinage, rechargeable batteries, electric guitar strings, microphone capsules, and special alloys.
