Ni95Al5 (also known as NiAl 95/5, TAFA 75B, Metco 8400, PMET 885, F-80NA, or N9) is a nickel-aluminum alloy containing 95% nickel and 5% aluminum, designed specifically for thermal spray applications. It is characterized by dense coating formation, high-temperature oxidation resistance, thermal shock resistance, and exceptional bonding strength. This self-bonding alloy is widely used as a bond coat to improve adhesion between substrates and top coatings, or as a standalone protective coating.
