Description
Nimonic 90 is a high-strength, heat-resistant alloy primarily composed of nickel, with significant additions of chromium (20%) and titanium (2.8%) to enhance its performance at elevated temperatures. Known for its excellent resistance to oxidation, creep, and corrosion, Nimonic 90 is commonly used in the aerospace industry, particularly for turbine blades and other high-stress components operating at temperatures up to 950°C.
Compared to alloys like Inconel 718, Nimonic 90 offers better high-temperature strength, making it a preferred material for gas turbines, jet engines, and combustion chambers. Its ability to withstand extreme thermal cycling and mechanical stresses makes it a reliable choice for critical aerospace applications.
Nimonic 90 is also referred to as UNS N06090, and is available in various forms including bars, plates, and forgings, providing versatility in different industrial applications.
