Nimonic alloy 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 920°C. Nimonic Alloy 90 is typically used in extreme stress applications such as turbine blades, hot working tools, exhaust reheaters, disc and high-temperature springs. Availability Alloy 80A is available in Round Bar, Flat Bar, Rod, Tube, Plate, Sheet, Strip, Forging Stock and Wire. For all stock availability contact Sales.
