A nickel based alloy is an alloy whose main constituent is nickel. Nickel and nickel based alloys are vitally important to industry because of their ability to withstand a variety of severe operating conditions involving corrosive environment, high temperatures, high stresses, and combinations thereof.
Nickel and nickel based alloys have many applications, most of which are for resistance to corrosion and/or heat. Examples include aircraft gas turbines, steam turbine power plants, turbochargers and valves in reciprocating engines, prosthetic devices, heat treating equipment, pollution control equipment, coal gasification and liquefaction systems, and components in pulp and paper mills.
