Nimonic® Alloy 90

Nimonic® Alloy 90 / 2.4969 – 2.4632 / UNS N07090

Nimonic® Alloy 90 is a precipitation hardening nickel-chromium-cobalt alloy specifically developed for applications at extremely high temperatures. The alloy offers excellent creep resistance and high resistance to stress rupture, even at temperatures up to approximately 920°C.

Additionally, Nimonic® Alloy 90 is highly resistant to corrosion and oxidation, making it a durable choice for applications in thermally and mechanically demanding environments such as gas turbines.

Properties of Nimonic® Alloy 90

Nimonic® Alloy 90 combines high mechanical strength with excellent creep resistance and stress-rupture resistance, especially under prolonged high-temperature loads. The composition consists of nickel as the base element, with significant amounts of chromium, cobalt, and titanium, providing both oxidation resistance and structural stability.

The alloy is hardened through precipitation (aging), which significantly enhances tensile strength and resistance to deformation. Additionally, Nimonic® Alloy 90 is highly resistant to oxidation and corrosion, maintaining its integrity even in aggressive and hot environments.

These properties make the material ideal for use in aerospace engines and power plants where long-term performance under extreme conditions is required.

Applications of Nimonic® Alloy 90

Nimonic® Alloy 90 is primarily used in the aerospace industry, with applications such as blades and discs in gas turbines that are exposed to high rotational speeds and temperatures. Additionally, the alloy is utilized in tools and components that endure severe thermal stress, such as in industrial furnaces and power plants.

Due to its resistance to creep and oxidation, Nimonic® Alloy 90 is a reliable choice for critical components where failure is not an option.

Nimonic® Alloy 90 is the solution for applications demanding maximum performance under extreme temperature and load conditions.
