Kanthal® SW 010 is a ferritic iron-chromium-aluminum alloy (FeCrAl alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings, resistant to high-temperature oxidation and corrosion.
Typical applications for Kanthal® SW 010 are bond coats in high-temperature coating systems, protective coatings in high-temperature atmospheres containing sulphur or carbon and protective coatings against scaling of conventional low alloy steels.

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.
