Nimonic 263

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.

Applications:

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