Metco 8400 Thermal Spray Wire
 
Metco 8400 thermal spray wire is an austenitic nickel-aluminium alloy (NiAl alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings. It is a good kind of thermal spray wire.
Typical applications for metco are bond coats, as protective coatings against high-temperature oxidation, protective coatings against scaling of conventional iron base alloys and as build-up coatings for dimensional restoration.
