METHOD FOR JOINING Al OR Al ALLOY MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for joining an Al or Al alloy member by which excellent joining strength can be obtained at a relatively low temperature without using molten metal such as brazing filler metal on joining. SOLUTION: Fluoride base flux 3 is applied to a part to be joined between an Al or Al alloy member and a metallic member 2 to be joined, and the part to be joined is heated and pressurized at about <=500 deg.C to join both members.
