Description of the Related Art In general, when brazing or soldering a low melting point aluminum material, a flux is used in order to remove an oxide generated in a joint part and perform a good joint, as in the case of brazing an ordinary aluminum material. To be done. For example, when a casting material is used for the brazing member, the brazing material has a low melting point of 95% Zn-5% Al, A4245 alloy (Al-1

No.), etc., to make the flux into a suspension and supply it to the joint part, and at the same time supply these brazing filler metals to the atmosphere or N
The flux brazing method of heating in 2 gas is common. The supply of the flux in this case is performed by spray coating of the flux suspension, brush coating, dipping coating in which the brazing component is dipped in the flux suspension, electrostatic coating of flux powder, or the like.

る。First, since water is often used when preparing a flux suspension, it is necessary to dry the water after the flux is supplied, and moreover, a hydrated film is easily formed on the surface of the brazed product and the brazability is improved. Is reduced. Also, in the case of spray coating, brush coating and electrostatic coating, there are some parts that cannot be applied or parts that are difficult to apply depending on the shape of the brazed product. If it cannot be applied, brazing will be defective. On the other hand, in the case of dip coating, the flux can be supplied to any part of the brazed product, but on the other hand, the flux is supplied to unnecessary parts as well, so the amount of flux used increases. Since the brazing cost is increased and the appearance of the product is deteriorated by the residual flux, sufficient process control is required for the flux cleaning and removing work after brazing.

In addition to Zn, Al and Si which are the main components, a metal and unavoidable impurities which are arbitrarily added for improving the function of the brazing material may be contained, and the composition of the three main elements is not particularly limited. However, in this Zn-Al-Si based alloy, the Zn content is 20 to 80 wt% and the Si content is 1 to
A range of 11 wt% is preferred. This is because if the content of each of these contents falls below the lower limit, the liquidus temperature of the flux-containing brazing material becomes high, making it difficult to bond the low-melting-point aluminum alloy material satisfactorily. This is because it becomes brittle and difficult to solidify. Particularly preferably, the Zn content is 25 to 55 wt% and the Si content is 3 to 7 wt%. If it is a Zn-Al alloy,
The Zn content is preferably in the range of 70 to 95 wt%, particularly 9

This is because if the amount of flux is less than 99: 1, sufficient flux action cannot be exhibited and good bonding becomes difficult, while if the amount of flux exceeds 70:30, it becomes brittle and solidification becomes difficult. Is. A particularly preferable ratio of the brazing material component to the flux component is 99: 1 to 85:15 by weight, and further 9
The range of 8: 2 to 90:10 is preferable.

金粉末等を用いても良いし、これらを併用しても良い。The flux-containing brazing filler metal for low temperature brazing according to the present invention is generally prepared by mixing brazing filler metal component powder such as Zn powder, Al powder, Si powder and flux component powder in a predetermined ratio, and mixing the mixed powder in a container. It is manufactured by compacting and solidifying by hot pressing etc. while degassing after filling in, and the density of the brazing filler metal is usually Zn, Al,
It becomes smaller than the theoretical value calculated from each material powder such as Si and flux. In the present invention, it is required to be 90% or more of the theoretical value. If the density of the flux-containing brazing filler material for low temperature brazing is less than 90%, the material powder is solidified, but there is a risk that it will be brittle due to pore communication to the inside, and a shape suitable for the joining material will be obtained. The secondary forming process is also difficult, and in fact, the function as a flux-containing brazing filler material for low temperature brazing becomes poor. Particularly preferably, the density of the flux-containing brazing material for low temperature brazing is 95% or more of the theoretical value. Also,
The brazing filler metal powder and the flux component powder are preferably finely pulverized in order to uniformly mix them and to densify the brazing filler metal structure. When producing a flux-containing Al alloy brazing material for low temperature brazing by such a method, Zn, Al, Si, etc. do not necessarily have to be used alone as a starting material, but an alloy powder having a predetermined composition, etc. May be used, or these may be used in combination.

Since it is blended at a ratio of 0 and the density is 90% or more of the theoretical value, the flux is supplied to the joint part together with the brazing filler metal component at the time of brazing, so the flux is supplied separately. There is no need, and the waxing process can be greatly simplified. Moreover, since an appropriate amount of flux is always supplied regardless of the shape of the joint, there is no risk of brazing failure due to an excessive supply of flux, and low-melting-point aluminum alloy materials of various shapes can be joined reliably and satisfactorily. Also, since flux adheres to unnecessary parts,
The process control of the cleaning work after brazing can be simplified and the flux consumption can be saved.
