Nimonic
High Temperature Alloy
◆ Nimonic90 has high tensile strength and creep resistance, good oxidation resistance and corrosion resistance, and is suitable for turbine discs, blades and high-temperature fasteners of turbine engines.
◆ Nimonic91 has high strength and anti-oxidation performance at high temperature of 650-1000°C, and is suitable for high-temperature components such as aero-engine blades, rocket engines, and nuclear power.
