摘要
PURPOSE: A vacuum brazing method for a high strength aluminum alloy using Cu is provided to weld an aluminum alloy in need of high strength and high rigidity using Cu as a filler. CONSTITUTION: A vacuum brazing method for a high strength aluminum alloy comprises the steps of treating the surfaces of an aluminum alloy and Cu metal, welding the aluminum alloy by brazing in the vacuum condition after placing the Cu metal on the welding part of the surface-treated aluminum alloy, and thermally treating the welded aluminum alloy. Herein, the surfaces of the aluminum alloy and the Cu metal are treated with mechanical polishing and electrolytic polishing. The aluminum alloy is 6061 series aluminum alloy, and the Cu metal is used as a filler.
