Aiman Metals provides high-performance Nimonic 90 Bars and Rods in Kuala Lumpur, Malaysia, suitable for use under extreme high-temperature and high-stress conditions. Nimonic 90 is a precipitation-hardened, nickel-chromium-cobalt alloy used for aerospace, power generation, and thermal processing. It shows great creep, oxidation, and fatigue resistance at high temperatures. Aiman Metals supplies precision-forged, heat-treated, and machined bars and rods in accordance with AMS 5829 and BS HR2 specifications. Our Nimonic 90 is utilized wherever greater than average mechanical integrity and high heat resistance is necessary for mission-critical applications.
Nimonic 90 has ~57% nickel, ~20% chromium, ~18% cobalt, with age-hardening titanium and aluminum. It has tensile strength greater than 1000 MPa and retains high creep and oxidation resistance up to 920°C temperature. The alloy possesses superior fatigue strength, ductility, and weldability. It withstands scaling and retains structural integrity in long-term thermal exposure and mechanical loading.

Yes, Nimonic 90 bars are highly suitable for high-temperature applications. They are known for excellent strength, oxidation resistance, and stability at elevated temperatures, making them ideal for aerospace and turbine components.
Yes, Nimonic 90 bar can be welded, but it requires careful control of heat and welding parameters. Typically, TIG (Tungsten Inert Gas) welding is recommended for best results.
Nimonic 90 rod is available in various sizes, typically from 1/8" to 12" in diameter. Common finishes include cold drawn, hot rolled, or bright polished, depending on the supplier.
Nimonic 90 Bars and Rods are applied in turbine blades, disc assemblies, exhaust valves, nuclear reactors, and combustion chambers. Its strength at high temperatures qualifies it for application in jet engines, gas turbines, and industrial furnaces. The alloy is also utilized in high-performance vehicle exhausts, marine applications, and heat-treated tooling. Nimonic 90’s fatigue and oxidation resistance protects against long-term thermal cycling and mechanically strenuous environments.
