GH4080A High Temperature Nickel-Chromium Alloy for Aerospace and Marine Engine Components

GH4080A is a nickel-chromium-based precipitation-hardened alloy developed for demanding high-temperature applications. Manufactured by KX-Alloy in Danyang, China, this alloy offers outstanding creep resistance, oxidation resistance, and mechanical strength in service environments up to 850°C.

With aluminum and titanium as key strengthening elements, GH4080A maintains structural integrity during long-term exposure to heat, making it ideal for use in aerospace turbines, marine engine valves, automotive fasteners, and railway components. Its excellent hot and cold workability ensures reliable fabrication into bars, plates, strips, wires, and more.

GH4080A complies with GB/T 14992 standards and is comparable to international grades such as GH4080A and Nimonic 80A. With no TCP phase formation after prolonged aging, this alloy is a preferred material for high-performance, heat-resistant applications across multiple industries.
