Coatings

Alcoa Howmet has been providing sophisticated coating services to the aerospace and power generation industries since 1963.  The advanced coatings supplied by our Whitehall, Michigan and Branford, Connecticut facilities are designed to extend the operating life of the most complex components by providing them with the highest degree of protection against the damaging effects of oxidation and corrosion.
 
We specialize in the coating of hot-section components cast in nickel-based alloys with equiax, directional solidification and single crystal orientation.  Alcoa Howmet's coating operations can also fulfill many of your welding, brazing and stripping needs.
