What is nickel-iron alloy?

Answer 1

A steel alloy made harder, stronger, and more resistant to corrosion than ordinary steel by the addition of up to five percent of nickel.

It is worth noting that MSN defines it as "a steel containing up to six percent nickel, sometimes with other metal added, usually to assist hardening during formation"

Answer 2

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 3

it's called Nife (chemical formula-NiFe)its very magnetic and is often used in magnets

Answer 4

A steel. There are many formulations of steels, all with different properties depending on the proportions of the alloying elements.

Answer 5

no its not
