What is Nickel and its Alloys?

Nickel (Ni) and its alloys are versatile metals that are widely specified for corrosion resistance. These alloys also have high-temperature strength, thermal expansion abilities, and special magnetic properties. They are used for a broad range of applications such as aircraft gas turbines, nuclear power systems, medical applications, in the chemical and petrochemical industries, and in steam turbine power plants. Other uses that include Nickel’s unique physical characteristics include shape memory alloys, soft magnetic alloys, low expansion alloys, and electrical resistance alloys.
