    摘要： A brazing agent consists essentially of a compacted powder mixture of an aluminum-silicon alloy and a flux, the agent having an apparent density of 90% or more of a theoretical density. Si is contained at about 3-15% by weight of all the elements other than the flux, so that the ratio in weight of all the elements to the flux is from 99.9:0.1 to 70:30. The brazing agent may further contain one or more elements selected from a group consisting of zinc, tin and indium, at about 0.1-5%, 0.01-0.5% and 0.01-0.5% by weight of all the elements other than the flux, respectively. A brazing sheet may be of such a structure that a core sheet made of aluminum or its alloy has at least one surface clad with a skin layer which has a thickness of 10 .mu.m or more for each surface.

    摘要： In a method of hot brazing aluminum articles, the steps of: interposing an amount of a flux-containing brazing agent (12) between portions of aluminum articles (11, 11) which are to be adjoined one to another; gripping the portions with a pair of heaters (13); and then activating the heater so that heat conducted therefrom melts the brazing agent (12) to braze the aluminum articles (11), are carried out in this order. The brazing agent (12) is a compacted agent composed of a matrix powder and a flux powder, at a ratio in weight of 99.9:0.1 to 70:30, and the agent has a density corresponding to 90% or more of a theoretical value. The articles (11) may be pressed one to another towards adjoining surfaces while they are being heated by the heater (13), or the heaters (13) are slided relative to the adjoining portions so that they are heated wholly, or the adjoining articles (11, 11) are urged towards each other while the heaters (13) are being slided relative to them so as to entirely heat them, so that the brazing is carried out efficiently to manufacture brazed products which are of a higher brazing strength.
