Hangbo Alloy Group
Shanghai · Est. 2012
From turbine discs spinning at 15,000 RPM to rocket engine thrust chambers at 1,600°C, aerospace demands materials that never fail. Hangbo Alloy Group supplies flight-critical nickel superalloys certified to AMS, GE, PWA, and Rolls-Royce specifications.
Aerospace engines operate at temperatures exceeding 70% of the alloy melting point. Components face cyclic thermal stress, centrifugal loads, oxidation, and creep — simultaneously. Material certification is non-negotiable.
