Diameter:0.2mm High-purity nickel wire is an indispensable part of vacuum material, silver-white metal, density 8.9 g / cm 3 . The temperature of 1455 C, the boiling point of 2730 C. Valence 2 and 3. Hard, magnetic and good plasticity. It has good corrosion resistance, is not oxidized in the air, and is resistant to strong alkali. It can be slowly dissolved in dilute acid, releasing hydrogen to produce green positive divalent nickel ion Ni2+; no reaction occurs in the oxidant solution including nitric acid. A ferromagnetic metal element that is highly polished and resistant to corrosion. Mainly used in alloys (such as nickel steel and nickel silver) and as a catalyst (such as Raney nickel, especially as a catalyst for hydrogenation), can be used to make money, etc., plating on other metals can prevent rust.
