Incoloy A286 Nickel Alloy
Incoloy A286 (UNS S66286) It is a nickel-based superalloy based on an Fe-25Ni-15Cr matrix, which achieves comprehensive strengthening through the addition of molybdenum, titanium, aluminum, vanadium and trace boron, and complies with ASTM technical standards. This alloy is mainly used in the manufacture of high-temperature load-bearing components of aero-engines that work for a long time at temperatures below 650°C.
