Abstract
An improved method for brazing aluminum and alloys of aluminum in which at least one of the surfaces to be joined is coated with a controlled quantity of metallic manganese which is effective during the high temperature vacuum brazing operation to promote a wetting and flow of the brazing filler metal between the surfaces to be joined and a penetration of the tenacious aluminum oxide film thereon, thereby producing a substantially uniform and high strength bond.
