Predominantly made of nickel chrome, generally contain over 50% nickel. When heated forms a thick yet stable oxide layer that protects its outer surface from further attack. This makes it an ideal choice for extreme temperature and pressure application, where steel and aluminium would succumb to thermal creep.

Available in numerous grades, the Inconel alloy exhibits shifting characterises with slight variation in their variations in their chemistry.

In it most basic form typical application would include the food industry and heat treatment components when alloyed with other elements. However further strengthening and stiffening permit it uses in the most demanding areas of marine, aerospace and chemical processing industries. Alloyed to its peak performance, Inconel then become the material of choice in the most critical environments of turbine blades rocket engines and key nuclear industry components.
