the alloy A-286 boasts extremely high yield strength and creep-rupture strength as well as great fabrication characteristics and weldability.The Incoloy A-286 nickel alloy is an iron-nickel-chromium alloy with additions of molybdenum, titanium, aluminum, vanadium and trace amount of boron that stiffen the alloy matrix, thus providing high mechanical strength. At the temperature under 650.



These superior prosperities of this high temperature alloy make it useful for high temperature bearing components of aircraft engine, such as turbine disc, compressor disc, rotor blade and fastener.
