AMS 4880 Nickel Aluminum Bronze 'E': Aerospace-Grade Seawater & Corrosion Champion
(SAE-AMS-4880E | UNS C95800 HIP | CuAl9Ni5Fe4)
Cu 79-85% · Al 8.5-9.5% · Ni 4.0-5.5% · Fe 3.5-5.0% · Zero-Pitting Alloy · Extreme Pressure Survivor
Product Overview: Where Failure Is Not an Option
Trusted by Boeing for helicopter rotor bearings and Schlumberger for subsea blowout preventers, AMS 4880 'E' grade delivers unmatched reliability in corrosive, high-stress environments. This hot isostatically pressed (HIP) nickel aluminum bronze withstands 10.000+ psi seawater pressure and resists cavitation erosion 8x better than 316L stainless steel. Compliant with AMS 4880 Rev E and MIL-B-24480A for aerospace and defense applications.
