Nimonic alloy 90 UNS N07090 used for turbine blades
Nimonic alloy 90 (UNS N07090) is a wrought nickel-chromium-cobalt base alloy strengthened by additions of titanium and aluminum. It has been developed as an age-hardenable creepresisting alloy for service at temperatures up to 920°C (1688°F). The alloy is used for turbine blades, discs, forgings, ring sections and hot-working tools.
