Nickel alloys have nickel as their base element. Pure nickel is very tough with exceptionally good corrosion resistance.
It is a versatile element and readily alloys with almost all metals. The nickel alloys have chromium, iron and sometimes molybdenum in their alloying elements. They are often used in applications that require excessive heat resistance. They can be subjected to aggressive environments at high temperatures.
A combination of reliability, durability, and utmost strength is provided by all nickel alloys. They are also used where controlled thermal expansion of the alloy is required. Their common applications include turbines, power plants, aircraft components, etc.
