摘要： A process for brazing a die-cast aluminum material, wherein a die-cast aluminum material produced at a gate speed of 20 m/s or higher is used to be brazed at a brazing temperature of 500.degree. C. or lower. Further, it is preferred that the die-cast aluminum material is produced under a casting pressure of 600 kgf/cm.sup.2 or lower, or that the die-cast aluminum material is produced while depressurizing a mold. Brazing may as well be conducted using a brazing filler metal material composed of 6 to 24 wt. % of Al and the balance consisting of Zn and impurities. In the foregoing manner, the die-cast aluminum material can be brazed by heating it to a high temperature.

摘要： Objects of the present invention are to provide a brazeable aluminum alloy cast material which can be manufactured brazeable products without lowering the productivity and the method of brazing a cast material.The cast material is composed of: 0.5-4.5% by weight of Mn; 0.5-3% by weight of Si; 0.5-1% by weight of Fe; and the balance composed of aluminum and impurities. In the method of brazing the cast material, a brazing agent and/or flux are used, the brazing agent is composed of: 25-65% by weight of Zn; 2-7% by weight of Si; and the balance composed of aluminum and 0.1% or less of Fe as one of impurities. The flux is a mixture of: 0.5-5% by weight of LiF; 1-10% by weight of ZnCl.sub.2 ; 1-5% by weight of K.sub..alpha. AlF.sub..alpha.+3 (.alpha. is an integer not less than 1.); and the balance composed of BaCl.sub.2 -KCl-NaCl.

摘要： A first aluminum brazing alloy for cold brazing, comprises 70 to 90% by weight of zinc and 0.05 to 5% by weight of titanium with the balance consisting of aluminum and impurities. A second aluminum brazing alloy for cold brazing, comprises 30 to 70% by weight of zinc, 1 to 7% by weight of silicon, and 0.05 to 5% by weight of titanium with the balance consisting of aluminum and impurities. Brazing alloys having these compositions have a low melting point and can well wet a base metal. Further, use of the above aluminum brazing alloy for cold brazing enables a low-melting aluminum material to be well brazed at 400 to 550° C.

摘要： A tank for a heat exchanger is made of resin as a unit by molding with a pair of forming dies and includes a fit base portion for supporting an end of the tube portion to keep a fluid communication between the tank and the tube, and a box-shaped receiving portion integrally formed with an outer side surface of the tank to receive a fastening part. The receiving portion includes a bottom wall extending horizontally, a front wall extending vertically from a front end of the bottom wall and a pair of side walls extending vertically from side ends of the bottom wall in a manner to form a top opening thereby. A notch portion is provided at the front wall and the bottom wall in such a manner that the notch portion extends from a middle portion of the front wall to the bottom wall. The receiving portion for receiving the fastening part can be structured as a unit with only a pair of dies and without an additional mechanism.
