Nickel

Extracted from Collier's Encyclopedia
Nickel, symbol Ni, is element number 28, at. wt. 58.69, density 8.9, m.p. 1,455 degrees celcius, b.p. 2,900 degrees celcius. Nickel is the last member of the first triad in Group VIII of the periodic table. It is a transition element, associated with iron and cobalt, with which it occurs in nature; these three metals resemble one another closely in both physical and chemical properties. . ..

Properties.

Nickel is a white metal, hard (Brinell for cast metal 90- 110), malleable, and ductile. Below 340 degrees C. it can be magnetic. It conducts heat and electricity fairly well. It takes a high polish, and remains bright in ordinary air for a long time. It gradually becomes dull gray in color, especially in air containing sulphur compounds. When the metal is dipped in nitric acid it becomes passive...

Uses.

The uses of nickel depend largely on its ability to resist corrosion, a property also imparted in large measure to its alloys. By far the largest use of nickel is in the production of alloy steels, such as stainless steel. ... Alnico (nickel , cobalt, iron, and aluminum) powerfully magnetic, making possible the construction of small instruments requiring permanent magnets.
