NIMONIC® Alloy 263
2.4650 / UNS N07263
A nickel-cobalt-chromium alloy with additions of molybdenum which can achieve high strength through age-hardening. The alloy was designed specifically to combine good high temperature strength properties with excellent formability (in the annealed condition). It has high strength at temperatures up to 816°C and excellent oxidation resistance up to 982°C. The alloy is particularly suited to sheet fabrications and is used in both aircraft turbines and industrial gas turbines for rings, casings, low temperature combustors and transition liners.
