    摘要： A method of connecting a plurality of aluminum alloys molded as a die cast member while maintaining the molded shape of the alloy is provided. An intermediate material in the form of plate or powder made of aluminum alloy is allowed to intercalate between mutually connecting surfaces of die cast members, the die cast member and/or intermediate material is constituted of an aluminum alloy, at least one of mutually contacting surfaces of the connecting surfaces and the intermediate material is constituted of a rough surface to enhance electric resistance between the contacting surfaces and the connecting surfaces are connected by applying electric current through the connecting surfaces.

    摘要： A method of simply and strongly connecting a plurality of aluminum alloys molded as a die cast member while maintaining the molded shape of the alloy is provided. An intermediate material in the form of plate or powder made of aluminum alloy is allowed to intercalate between mutually connecting surfaces of die cast members, the die cast member and/or intermediate material is constituted of an aluminum alloy containing 0.3 to 2.5 wt % of magnesium, at least one of mutually contacting surfaces of the connecting surfaces and the intermediate material is constituted of a rough surface having a surface roughness of 20 to 300 μm to enhance electric resistance between the contacting surfaces and the connecting surfaces are connected by applying electric current through the connecting surfaces to cause heat generation under mutual pressing while promoting the reduction reaction of an aluminum alloy oxide membrane by magnesium.
