Nimonic® 80A is a Nickel-Chromium alloy which is precipitation hardenable. It has largely been superseded by Nimonic 90 and Inconel X-750, but because of the low Cobalt content, it is still specified for nuclear applications. Nimonic® 80A performs well in applications where high temperature and continuous stress is a significant consideration. Beyond nuclear applications, it is traditionally used in applications such as gas turbines, as well as for exhaust valves in racing engines and spindles and fasteners for the motorsport sector. Nimonic® 80A is also known as Nicrofer 7520 Ti, Pyromet 80A, Superimphy 80A, and Udimet 80A.

A Nickel-Chromium-Molybdenum alloy with excellent corrosion resistance in a wide range of corrosive media, being especially resistant to pitting and crevice corrosion. Inconel® 625 provides resistance to stress corrosion cracking to chloride ions, making it a favourable choice for sea water applications. The alloy also provides commendable oxidation resistance, with its high strength a result of the stiffening combination of Molybdenum and Niobium on the alloy’s Nickel-Chromium base.

Nimonic® 75 is a Nickel-Chromium alloy with good corrosion and heat resistance, and contains Titanium and Carbon as additives. Initially used as turbine blades in the 1940s, Nimonic® 75 is readily fabricated and welded, and is now more regularly used in gas turbine engines, industrial furnaces and nuclear engineering. Nimonic® 75 is also known as Nicrofer 7520.

A Nickel-Chromium alloy with an addition of aluminium, Inconel® 601 gives outstanding resistance to oxidation and other forms of high temperature corrosion. It also has high mechanical properties at elevated temperatures.

A Nickel-Chromium alloy with good resistance to oxidation and corrosion at high temperatures. An austenitic sold-solution alloy, Inconel® 600 also shows good resistance to chloride-ion stress-corrosion cracking. Inconel® 600 is a spring quality wire, cold drawn and with excellent mechanical properties, often used in furnace components, chemical and food processing, and nuclear engineering. of high strength and good workability.
