Nimonic alloys are made up of nickel and chromium. These alloys are characterised by their high-temperature low-creep and high performance. Additives like titanium and aluminium are used for enhancing the strength of the alloy.
Nimonic 75 is an 80/20 nickel-chromium alloy containing titanium and carbon as additives. Nimonic 75 was first introduced for use as turbine blades during the 1940s. Nimonic 75 is readily fabricated and welded. Nimonic 75 alloy exhibits good corrosion resistance, mechanical properties and heat resistance.
Available forms of Nimonic 75 are extruded section, hexagon flats, pipe, plate, strip and wire.
