Nimonic® Alloy 263

Nimonic® Alloy 263 / 2.4650 / UNS N07263

Nimonic® Alloy 263 is a precipitation hardening nickel-chromium-cobalt alloy with molybdenum as an additional alloying element to enhance its mechanical properties. This superalloy offers an outstanding combination of high strength, corrosion resistance, and good formability, making it a reliable choice for applications in demanding high-temperature environments.

Thanks to its balanced composition, Nimonic® Alloy 263 is particularly suitable for thermally and mechanically demanding applications in the energy and aerospace sectors.

Properties of Nimonic® Alloy 263

Nimonic® Alloy 263 is designed for use at high temperatures, where the material can be exposed to oxidative and mechanical stress for extended periods without losing structural integrity. The addition of molybdenum contributes to increased strength, while cobalt and chromium ensure oxidation and corrosion resistance.

The alloy is precipitation hardening, meaning its strength increases through controlled heat treatment. At the same time, the material retains relatively good ductility in the solution-annealed state, which facilitates machining and forming—an important advantage over other nickel alloys with similar properties.

Furthermore, Nimonic® Alloy 263 offers excellent weldability, allowing it to be efficiently processed in complex assemblies.

Applications of Nimonic® Alloy 263

Nimonic® Alloy 263 is extensively used in gas turbines, with applications such as turbine casings, rings, and plates that are exposed to high temperatures and pressure. The combination of thermal stability and workability makes the alloy particularly suitable for both static and rotating components in turbine constructions.

Additionally, Nimonic® Alloy 263 is utilized in other high-temperature systems where durability and oxidation resistance are required, including applications in power generation and aerospace technology.

Nimonic® Alloy 263 is the superalloy for high-performance applications that demand a balance between heat resistance, strength, and formability.
