Metco 443NS, Amdry 960 and Amdry 510 are nickel chromium aluminum composite powders. Coatings of these powders are used for oxidation and corrosion resistant (e.g., resist corrosive gases, etc.) applications at temperatures up to 980 °C (1800 °F). However, Metco 461NS is preferred for improved oxidation and hot corrosion resistance.
