Inconel® X750 is a Nickel-Chromium alloy made precipitation hardenable by additions of Aluminium and Titanium, having creep-rupture strength at high temperatures to about 700°C (1290°F). It is widely used for high temperature conditions but is not as strong as Nimonic 90, but Inconel® X750 also holds exceptional properties all the way down to cryogenic temperatures.

Incoloy® 825 is a Nickel-Iron-Chromium alloy with additions of Molybdenum and Copper. It has excellent resistance to both reducing and oxidising acids, to stress-corrosion cracking and to localised pitting. It is also especially resistant to sulphuric and phosphoric acids. Alongside Inconel® 625, Incoloy® 825 is one of the most important nickel alloys for the oil and gas industry. Thanks to the balance of elements, it offers exceptional resistance to chloride stress corrosion cracking, as well as crevice corrosion and general corrosion. Incoloy® 825 is also known as Nicrofer 4221, Superimphy 82 and Ferrochronin 825.

Nickel-Chromium alloy being precipitation hardenable and having high creep-rupture strength at high temperatures to about 700°C (1290°F). It has higher strength than Inconel® X-750 and better mechanical properties at lower temperatures than Nimonic 90 and Inconel® X-750. Inconel® 718 has exceptional weldability compared to the Nickel-base super alloys hardened by Aluminium and Titanium.

A Nickel-Chromium-Cobalt alloy being precipitation hardenable, having high stress-rupture strength and creep resistance at high temperatures up to about 950°C (1740°F). It is widely used and a well proven alloy in high temperature conditions. Some typical applications for Nimonic® 90 include turbine blades, discs, forgings, ring sections, hot-working tools and other extreme environments. Nimonic® 90 is also known as Superimphy 90, Pyromet 90, and Udimet 90.

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 It has largely been superseded by Nimonic 90 and Inconel X-750, but because of the low Cobalt content, it is still specified for nuclear applications.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.

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.
