Nimonic Alloy 75

Nimonic alloy 75 - A Nickel-Chromium Alloy

Nimonic alloy 75 is made from nickel and chromium with modulated supplements of carbon and titanium. It was first used for turbine blades in prototype Whittle jet engines. It is also utilised for sheet applications that require scaling and oxidation resistance along with medium strength at high temperatures. It is used in applications like furnace components and gas turbine engineering. Nimonic alloy 75 suppliers and Nimonic alloy 75 manufacturers like Supreme Engineering Limited are responsible for the development of this alloy.

The alloy was first made during the 1940s in England. It is readily welded and fabricated. This particular alloy has good corrosion resistance, heat resistance and mechanical properties. It is offered in standard forms such as hexagon flats, strip, extruded section, wire and strip. It is also used for industrial thermal processing and heat treatment equipment.

Features of Nimonic alloy 75:

  • Resistant to corrosion.
  • Resistant to high heat temperatures.
  • Used for high temperature static applications.
  • Oxidation resistant at high temperatures.


The various forms of Nimonic alloy 75 are covered by the following standards:

  • ASTM B637
  • AMS 5766 and 2.4952.
