Joined body of dissimilar metals of steel and 6000 series aluminium alloys and process for the manufacture of the same. |
摘要 |
A joined body of dissimilar metals which is produced by joining a steel material and a 6000 series aluminum alloy material, wherein the steel material to be joined has a specific composition and is specified in the compositions of outer surface oxide layer and the aluminum alloy material to be joined is a 6000 series Al-Mg-Si-base aluminum alloy having a specific composition. In the joined body of dissimilar metals, a content of Fe at a joint interface on the aluminum alloy material side is regulated, and a reaction layer of Fe and Al is formed at the joint interface of the joined body of dissimilar metals. The joined body of dissimilar metals exhibits high joint strength. |
