An inexpensive bonding method is provided to bond materials constituted of an aluminum-based metal to each other at a low temperature and a low pressure while inhibiting deformation, without requiring the use of a flux and minimizing the influence on the base materials and the periphery. Also provided are various bonded parts obtained by the bonding method. An insert material comprising Zn as an element that undergoes a eutectic reaction with Al is interposed between two materials constituted of an aluminum-based metal. The two materials are heated, while being pressed against each other, to a temperature at which the eutectic reaction takes place, thereby generating, at the bonding interface between the two materials, a melt due to the eutectic reaction with some of the Al contained in the base materials and discharging the Al oxide films from the bonding interface together with the melt. Thus, the two materials are bonded.

Method for bonding aluminum-based metals

In joining members to be joined () by heating the members to be joined () that are mated with intervening an insert () while applying opposing loads to the members to be joined (), so as to allow eutectic reaction to occur between the members to be joined () and the insert () to discharge a eutectic melt from a joining plane along with an oxide film () of the members to be joined, the members to be joined () are brought into contact with the insert () so that the oxide film () is broken by a stress concentrating means previously provided at least one of joining portions breaks to produce a starting point of the eutectic reaction.

Joining method and joining component

A method of bonding dissimilar metals, a bonding structure formed by such a method and a bonding apparatus for performing such a method. The resulting bond is capable of preventing corrosion (e.g., electric corrosion) resulting from contact of the dissimilar metals and obtains a dissimilar material joint exhibiting anti-corrosive property and bonding strength at low costs. The method includes overlapping two materials made from dissimilar metals having a seal material interposed therebetween and discharging the seal material from a bonding interface and bonding the two materials in direct contact with each other.
