Nickel alloys generally fall into three categories – heat resistant alloys, corrosion resistance alloys controlled expansion alloys. A wide variety of alloys have been developed often with specific applications in mind. Aerospace, Oil & Gas, nuclear and petrochemical industries are all major users of these alloys although they are used in many other harsh or extreme environments.
