What type of metal is nickel?

Answer 1

Nickel-iron alloy is an alloy of nickel and iron, as might be inferred from the question. By combining nickel and iron in different proportions, we can manufacture a number of extremely useful alloys. Invar is just one of them, and it is important because it has the lowest rate of thermal expansion of any known metal or metal alloy (up to a few hundred degrees C). This makes for a good metal-to-glass seal in products that don't get super hot. Nickel and iron alloys have been essential in many applications in the manufacture of thermostats. The chances of your having at least one in your home are excellent. The "magic" in these nickel-iron alloys has been known for well over a hundred years, though they have been refined throughout all this time.

it's also called Invar

Answer 2

Nickel ---- Ni and atomic number 28. It is a silvery-white lustrousmetal with a slight golden tinge. It is one of the four ferromagnetic elements at about room temperature. Its use has been traced as far back as 3500 BC, but it was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook its ore for a copper mineral. Its most important ore minerals are laterites, including limonite and garnierite, and pentlandite. Major production sites include Sudbury region in Canada, New Caledonia and Russia. The metal is corrosion-resistant, finding many uses in alloys, as a plating, in the manufacture of coins, magnets and common household utensils, as a catalyst for hydrogenation, and in a variety of other applications. Enzymes of certain life-forms contain nickel as an active center making the metal essential for them.

Answer 3

Nickel silver, also called German silver, alpaca, or electrum, isn't actually silver. It's an alloy of copper and nickel, often including zinc and occasionally tin.

Nickel silver has a number of properties that give it a broad range of uses from tableware to restaurant and hospital equipment. Its silvery color works well in those applications, it's inexpensive compared to real silver, it's more wear-resistant than real silver, and it's both malleable (easy to form) and ductile (can be drawn into thin wires or sheets).

Sometimes people focus on the word "silver" in "nickel silver", not realizing (or forgetting) that it's entirely base metal. Unscrupulous sellers have been known to exploit that confusion in order to scam buyers.

Answer 4

Nickel nitrate is a compound. It is formed by Reaction between Ni and nitric acid.
