Nimonic 263 (Alloy 263), identified as UNS N07263 and W.Nr. 2.4650, is a nickel-based superalloy specifically designed for high-temperature applications. It offers excellent resistance to oxidation, corrosion, and creep, as well as superior strength at elevated temperatures, making it suitable for extreme conditions.
Common applications of Nimonic 263 include gas turbine blades, hot sections of aircraft engines, and other high-stress, high-temperature components. Its durability and ability to maintain mechanical properties under thermal stress make it ideal for aerospace and power generation industries.
