Kanthal SW 806 is an austenitic nickel-aluminium alloy (NiAl alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings.

Typical applications for Kanthal SW 806 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.

Depending of surface finish requirements, the coating may be machined by turning or grinding. For rougher surface, turning using carbide tools, light cuts and efficient cooling to avoid overheating is recommended. Grinding in fine steps using cooling, light pressure and clean wheels gives smoother finish.

Typical coating properties

Summary of results obtained when spraying with a conventional Arc Spray gun, using varying spraying parameters.

Deposition efficiency (%)60-70
Hardness HV (300g)180-250
Surface roughness (µm)15-28
Porosity (%)3-7*
Oxides (%)10-25*

*) These results are obtained when using air as spraying gas. Also nitrogen has been used, resulting in lower rates of porosity and oxides.
