ALLOY 90

Nickel alloy

UNS N07090

Alloy 90 is a precipitation-hardened nickel-based superalloy developed to provide very high mechanical strength and excellent creep resistance at high temperatures. Thanks to its high cobalt content and γ’ phase hardening, it is particularly well-suited for aerospace and industrial applications subject to severe thermomechanical stresses.
