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.
