Home > Nimonic 90 Sheet and Plates
Okoye Nickelalloys is a trusted manufacturer and supplier of high-quality Nimonic 90 Sheets and Plates in Kinshasa, Congo. Nimonic 90 is a nickel-based superalloy known for its excellent strength, oxidation resistance, and high-temperature stability, making it suitable for demanding applications in aerospace, gas turbines, and industrial sectors. These sheets and plates provide superior performance under extreme conditions, offering excellent mechanical properties such as high tensile strength and resistance to creep. We offer a wide range of Nimonic 90 products tailored to meet specific customer requirements, ensuring the highest standards of quality and reliability.
UNS N07090 is a nickel-based superalloy composed primarily of nickel (up to 90%), chromium (14-16%), and cobalt (1-2%). It also contains small amounts of titanium (0.5-1.5%), aluminum (0.5-1%), and molybdenum (1-2%) to enhance its mechanical properties. This alloy exhibits excellent high-temperature strength, oxidation resistance, and creep resistance, making it ideal for applications such as turbine blades, gas turbines, and industrial equipment. It has a tensile strength of approximately 900-1100 MPa and a yield strength of 500-700 MPa. Nimonic 90 maintains its integrity at elevated temperatures up to around 950°C, providing reliable performance in demanding environments.
