Alloy 90 (Nimonic 90) is a precipitation hardenable nickel-chromium-cobalt alloy strengthened by the addition of Titanium and Aluminium. Alloy 90 has a high stress rupture strength and creep-resistant at temperatures to about 920°C. Alloy 90 is typically used on such things as turbine blades, hot working tools and high-temperature springs.
