Nimonic 263

NIMONIC 263 (UNS N07263/W. Nr. 2.4650), a nickel-base alloy produced via air melting, was created by RollsRoyce (1971) Ltd. to provide an increased level of ductility in welded assemblies when compared to NIMONIC 80A. Its high levels of chromium and small amounts of aluminum and titanium allow it to excel in high-temperature applications in modern power and aerospace industries, with impressive resistance to oxidation and carburization.

Nimonic 263

Essential details
Nimonic 263 is a nickel-based superalloy developed by Rolls Royce in the 1950s. It is known for its strength and durability at high temperatures, making it one of the most widely used alloys in gas turbine engines.

The primary element in Nimonic 263 is nickel, which makes up 73% of the alloy by weight. The remainder of the alloy is composed of chromium (20%), cobalt (5%), and molybdenum (2%). These elements work together to create an incredibly durable and heat-resistant material. Thanks to its low coefficient of thermal expansion, it can withstand extreme temperature fluctuations without cracking or deforming. This makes it ideal for use in high-performance engines subjected to rapid temperature changes over short periods


Nimonic Alloy 263 is mainly used in gas turbine hot section components.
