Nimonic 90

Essential details
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.


Traditionally used in the production of gas turbine blades and hot working tools, Nimonic 90 is also popular in the motorsport and automotive sector.

The alloy is useful in applications where high mechanical stress and high temperature is a consideration, including specific engine applications, high-temperature springs and high-performance engine valves. The product is also a preferred choice for extreme high boost pressure turbocharged applications.
