In the case of the above-mentioned conventional example 1, since it is necessary to plate the aluminum alloy, the process is complicated and the brazing cost is high. Further, since solder (soft solder) is used for joining, the joint strength of the joint is significantly inferior to that of aluminum alloy and copper.

In the case of the conventional example 2, since a large mechanical pressure is required, the members to be joined are deformed. Moreover, since a pressure in a single direction is used, a bonded body having an arbitrary shape cannot be obtained. In Conventional Example 3, it is necessary to apply and remove the flux. In addition, it is necessary to use a large amount of expensive flux. In the case of Conventional Example 4, it is necessary to perform brazing at a high temperature of about 600 ° C. or higher, but when brazing is performed at such a high temperature, an aluminum alloy having a thickness of several μm or more is formed between the aluminum alloy and copper. Copper compound layer (Al-Cu
Intermetallic compound) is generated. Since this compound is very brittle, it is impossible to obtain a tough joint that can be put to practical use.

Si is also added to lower the melting point, but it may not be necessary depending on the amounts of Cu, Ge and Ag added. However, when Si is added, the melting point is lowered, so that brazing becomes easier. In the present invention, since one of the members to be joined is an aluminum alloy, the main component of the brazing material is preferably Al. The amount of Al, which is the remaining amount of each of the above-mentioned added components, is in the range of 30 to 80 wt%. A more preferable range of Al is 40 to 49 wt%. Al
If less than 30 wt%, the difference in the main components between the base material and the brazing material is too large, which may cause a decrease in joint strength.

When brazing is performed, it is necessary that the wax be wet with the base material and that the wax flow. But,
These properties also have a proper range, and when the wax is too wet or flows too much, problems occur such as contaminating the base metal and not properly staying in the portion to be brazed. Therefore, it is necessary to properly adjust the wettability and fluidity of the brazing material depending on the surface condition of the base metal, brazing conditions, the shape of the brazing object, and the like.

When Mg is added to the brazing filler metal of the present invention, the vaporization of Mg in the vacuum during brazing and the reduction of the oxide on the Al alloy surface by the vaporized Mg occur.
The surface of the Al alloy can be cleaned without using the flux, which causes the wetting of the brazing material.
When the atmosphere during brazing is unlikely to produce an Al surface oxide film, even if the amount of Mg added is about 0.1%, it is effective.
Depending on the brazing conditions, Mg needs to be about several%. However, addition of a large amount of Mg leads to contamination of the brazing furnace, so the upper limit of Mg is limited to 5%.

Bi has the effect of improving the wettability and fluidity of the base metal of the wax. Mn has the effect of suppressing the fluidity of the wax. In general, a braze containing Al as a main component may have too good fluidity, and thus the braze may not sufficiently remain in the gap of the brazing part. Mn is effective in improving this point. Since Zn has a low vapor pressure, it easily evaporates and has an effect of destroying the surface oxide film of the brazing portion, and therefore has an effect of improving the wettability of the brazing material. In this way, it is advisable to appropriately combine the addable elements Mg, Bi, Zn, and Mn according to the brazing atmosphere and the like.
