Precipitation Hardenable Nickel-Base Superalloy

The ATI C-263™ (UNS N07263) alloy is a high-temperature alloy commonly used in aircraft turbine engines and land-based gas turbines. It is typically supplied in the solution-annealed condition and then age-hardened by the customer after fabrication. The alloy is nickel based, but it also contains a significant amount of cobalt, which gives it superior high-temperature strength over other superalloys such as Types 718 and 625.

Typical applications require high strength at temperatures up to 1500°F (816°C) or oxidation resistance up to a temperature of 2000°F (1093°C). In addition to turbine engines, ATI C-263 alloy has also been used for components in automotive turbochargers.
