PURPOSE:To provide a joined body by copper base metal and aluminum base metal excellent in the high strength, the resistance against the high temperature, and the air-tightness in the joined boundary part of the dissimilar metals. CONSTITUTION:In manufacturing the joined body by dissimilar metals consisting of copper base metal and aluminum base metal by the rolling clad method, the diffusion welding method, the explosive welding clad method, the friction welding by pressure clad method or the like, the joined body of the dissimilar metals consisting of at least three layers is formed where titanium 3 is inserted as the insert member between the copper base metal (4 or 5) and the aluminum base metal (1 or 2). This joined body is excellent as the joint of dissimilar metals for structural use, and the joint of dissimilar metals for a super-high vacuum vessel. |
