Product Description
Nimonic 90 (UNS N07090 / W. Nr. 2.4632) is a nickel-chromium-cobalt base superalloy wire that has been specifically developed for age-hardenable, creep-resisting service in high-temperature applications. With a balanced composition including 18-21% chromium and 15-21% cobalt, plus titanium and aluminum for precipitation strengthening, this alloy maintains outstanding tensile and rupture strength even after prolonged exposure to elevated temperatures.
Manufactured to strict aerospace and industrial standards (including AMS 5829 and BS HR specifications), our Nimonic 90 high temperature resistant wire offers excellent fabricability in wire form while providing superior performance in hot sections of gas turbines, jet engines, and other thermal machinery. Whether used for springs, fasteners, or sensor elements, it ensures long-term dimensional stability and resistance to deformation under load.
Exceptional High-Temperature Performance: Maintains high strength and creep resistance up to 920°C (1688°F), ideal for continuous service in turbine engines.
Superior Oxidation and Corrosion Resistance: Excellent resistance to oxidation and hot corrosion in aggressive gas environments, including sulfur-containing atmospheres.
Precipitation Hardenable: Strengthened by titanium and aluminum additions for enhanced tensile strength (typically 1080 MPa min after heat treatment) and fatigue resistance.
High Creep and Rupture Strength: Outstanding stress-rupture properties, ensuring reliability under sustained high loads and thermal cycling.
Good Ductility and Fabricability: Available in cold-drawn or heat-treated conditions; suitable for forming into springs, wire forms, and complex shapes.
Density & Physical Stability: Density of approximately 8.18 g/cm³ with stable thermal expansion and conductivity across wide temperature ranges.
