A&A Coatings Nickel-Iron Aluminum Composite powder is specially designed to produce coatings which not only exhibit excellent self-bonding properties but also provide a significant improvement in machinability, wear and oxidation resistance.
The material undergoes an exothermic reaction during spraying and forms a strong metallurgical bond with the base metal. Coatings of Nickel-Iron-Aluminum relatively hard and can be machined using standard carbide tools to a very fine finish.
Additionally, these coatings are dense and can be used for oxidation resistant applications up to 815°C (1500°F). This makes Nickel-Iron-Aluminum a good undercoat for ceramic, nickel chromium and stainless steel type coatings in this environment.

There is no apparent thickness limitation. Nickel-Iron-Aluminum coatings can be applied thick without cracking, with minimum dependence on technique and temperature control.
A&A Coatings Plasma Sprayed Nickel-Iron-Aluminum can be applied to most substrates which have been cleaned to remove surface oxides. This cleaning is accomplished with a light grit blast. Additionally, a “Bond coat” is required in some cases. Please contact us for substrate specific requirements
A&A Coatings Plasma Sprayed Nickel-Iron-Aluminum coatings are best finished by machining. If you will be finishing our coating at your facility, please contact us for more information.
