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.
Chemical Composition: Ni ~ 95, Al ~ 5
Application or Properties: Spray wire with excellent bonding strength. Sprayed layers of this material are-resistant to variation in high temperatures and are used as a buffer layer for all other spraying alloys. Hardness, coating macro: Approximately HRc 22. Maximum working temperature: Approximately 800° C. Layer thickness: Approximately 0.1-0.15 mm.
