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.

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.

Personnel working with thermal spraying should be aware of the hazards connected to the process. They should be familiar with the use of equipment regarding, i.e. eye, skin, hearing and respiratory protection.

Personnel should be familiar with safety regulations regarding the complete process, including spraying and th spray equipment used. This product contains elements, which in certain combinations may be dangerous to your health. Material Safety Data Sheets are provided by Kanthal for this product, and should be read and understood before using the material.
