Kanthal^® SW 200 is an austenitic nickel-chromium alloy (NiCr 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 200 are protective coatings against corrosive gases, protection against scaling of conventional low alloy steels and build-up coatings for dimensional restoration.
