Alloy C263 (Nimonic C263) is a precipitation hardenable nickel-chromium-cobalt alloy with an addition of molybdenum for solid-solution strengthening. Alloy C263 has high strength and corrosion resistance as well as having good formability and high temperature ductility in welded structures. Alloy C263 is used in gas turbines for rings, casings and various sheet fabrications.
