    摘要： A core material of an aluminum brazing sheet restricts Mg to less than 0.3 wt % and Fe to not more than 0.2 wt %, and contains more than 0.2 wt % and not more than 1.0 wt % of Cu, 0.3 to 1.3 wt % of Si, 0.3 to 1.5 wt % of Mn and the balance of Al and inevitable impurities. A brazing filler material is formed on one surface of the core material by Al—Si based aluminum alloy. Also, a cladding material is formed on the other surface of the core material, and contains less than 0.2 wt % of Si, 2.0 to 3.5 wt % of Mg, not less than 0.5 wt % and less than 2.0 wt % of Zn and the balance of Al and inevitable impurities. Further, the value (cladding material hardness)/(the core material hardness) that is a ratio of the hardness of the cladding material to the hardness of the core material is not more than 1.5.

    摘要： A partly damaged aluminum heat exchanger such as an aluminum radiator is repaired by closing a hole in the damaged portion with an acrylic resin adhesive material. A certain area around the damaged portion is pressed down to form a cup-shaped depressed portion. The adhesive material is supplied to the depressed portion so that it is retained therein. Then, the adhesive material is hardened by curing it under the room temperature. The hardened adhesive material completely closes the hole with a sufficient thickness and strength because it is retained in the depressed portion. The adhesive material is cured in a relatively short time because the acrylic resin is used as the adhesive material.

    摘要： Disclosed is an aluminum alloy brazing sheet for heat exchangers, which has high strength after brazing, high corrosion resistance and excellent brazability. Specifically disclosed is an aluminum alloy brazing sheet (1a) for heat exchangers comprising a core member (2), a sacrificial member (3) formed on one side of the core member (2), and a brazing filler metal (4) formed on the other side of the core member (2) and composed of an Al—Si alloy. The sacrificial member (3) contains 0.03-0.30% by mass of Fe, 0.01-0.40% by mass of Mn, 0.4-1.4% by mass of Si, 2.0-5.5% by mass of Zn, not more than 0.05% by mass of Mg and the balance of Al and unavoidable impurities. In addition, the sacrificial member (3) has a crystal grain size of 100-400 & mgr;m after 5-minute heat treatment at 600 & ring;C during the brazing.
