Nimonic80A
Nimonic80A is a nickel-based superalloy consisting of nickel-chromium. Nickel-based superalloys with excellent high-temperature mechanical properties, high creep strength, high corrosion resistance and oxidation resistance under high temperature and high pressure, these advantages make Nimonic80A widely used in aviation, aerospace, power stations, transportation and other high-temperature hot forgings. The addition of aluminum and titanium to form a gamma phase dispersion strengthened high tempe2022-12-21
