を要求される場合は使用できない等の欠点がある。(Prior Art) Conventionally, a bonding method has been adopted as a method for joining a foamed aluminum member and an aluminum or aluminum alloy member (hereinafter simply referred to as an aluminum member). However, the stone-contact method has a problem in that the joint strength is low, and the contact strength deteriorates due to longitudinal changes in the adhesive. In addition, the adhesive is sensitive to heat and has a heat resistance and fire resistance of 1i.
There are drawbacks such as not being able to use it if required.

ンスによりきびしい粘度を似求される点ｒ劣っている。On the other hand, as a method for metallurgically joining a foamed aluminum member and an aluminum member, the joining is performed by interposing an aluminum brazing alloy layer having a melting point lower than the melting point of these members between the members to be joined. A four-digit method is possible. The conventional fluxless brazing method requires a high vacuum or a high-purity inert gas atmosphere, requires a special aluminum material for the brazing alloy, and is generally Compared to other brazing 4-glue methods, it is inferior in that it requires stricter viscosity due to the clearance of the brazing part 1) due to inferior solder filling properties.

Flux brazing is generally done by ju (
The waxing method using fluxes containing I and I as main components has traditionally been carried out, but these fluxes are woody and water-soluble, and are generally hygroscopic and do not absorb water in the presence of water. corrodes aluminum. Therefore, the residue of such flux must be removed by washing after the brazing process. However, when the bonding material is foamed aluminium 11, the bonding surface becomes an uneven surface, so it is difficult to completely remove the flux, and there is a problem that residual flux may cause corrosion due to moisture absorption.

In a thermal test, when the temperature was raised to 500°C, the adhesive melted, gas was generated, and the aluminum member peeled off. In addition, with the fluxless brazing method, only about 10 to 20% of the joint area could be obtained, and the joints could not be joined at all, so other tests were discontinued. Furthermore, when bonding was performed using chloride-based flux, n:c corrosion was severe after bonding, and V1 holes were generated in the aluminum member in the salt water fog test.
