NIMONIC 80A Nickel Alloy
NIMONIC 80A (UNS N07080) is a widely used nickel-based superalloy in the NIMONIC series. Based on NIMONIC 75, it has optimized the precipitation strengthening effect by adjusting the contents of titanium and aluminum, thus possessing more excellent high-temperature strength and creep resistance. It is particularly suitable for components that bear continuous loads in medium to high temperature environments (600-900°C).
