Heat transfer tubes and fins made of aluminum or aluminum alloy (in this specification, these are collectively referred to as aluminum materials) are brazed together, such as automobile radiators, evaporators, or heater cores. It is used when making core parts for heat exchangers, etc., to improve the brazing performance of parts to be joined together, and the purpose is to prevent aluminum materials from corroding due to residue remaining on the surface after brazing. It is said that

品を加熱炉中で加熱し、上記ろう材を溶融させる事でろ
う付は作業を行なう。When making a core part from aluminum material in this way, two or more parts to be brazed are assembled with a brazing material interposed between the surfaces that contact each other, and these parts are heated in a heating furnace. , Brazing is performed by melting the brazing filler metal.
このろう付は作業の際、ろう付は部分にはフラックスを
塗布し、ろう材とアルミニウム材とが馴染んで良好なろ
う付けが行なわれる様にしている。During this brazing process, flux is applied to the brazing area to ensure that the brazing material and aluminum material blend together to ensure good brazing.
この様にアルミニウム材のろう付は時に用いるフラック

国特許第１０５５９１４号に係る発明として紹介された
ものが知られている。In this way, fluxes that are sometimes used for brazing aluminum materials are known, such as those introduced in Japanese Patent Application Laid-Open No. 197396/1984 and the like as an invention related to British Patent No. 1055914.
この公報に開示されたフラックスは、フッ化アルミニウ
ム（ＡｌＦ２）とフッ化カリウム（ＫＦ）とを主成分と
するものである。The flux disclosed in this publication contains aluminum fluoride (AlF2) and potassium fluoride (KF) as main components.
又、この他にも、塩化物を主成分とするフラックスが、
アルミニウム材ろう付は用として従来から一般的に使用
されている。In addition to this, fluxes whose main component is chloride are
Aluminum brazing has been commonly used for many years.
（発明が解決しようとする問題点）
ところが、上述の様な従来のフラックスは、何れもろう
付は後にアルミニウム材に対して腐食性を有する残漬が
残り、ろう付は作業後に洗浄等の余計な作業が必要にな
った。(Problems to be Solved by the Invention) However, with the conventional fluxes described above, a residue that is corrosive to the aluminum material remains after brazing, and brazing requires unnecessary cleaning etc. after the work. A lot of work was needed.
即ち、特開昭５９−１９７３９６号公報等に開示された
フッ化アルミニウムとフッ化カリウムとを主成分とする

湿性、腐食性のある残渣が生じる事が避けられなかった
。That is, in the flux disclosed in JP-A-59-197396 etc., which has aluminum fluoride and potassium fluoride as its main components, potassium fluoride, which is corrosive to aluminum materials, remains after brazing. In the case of a flux containing chloride as its main component, it was inevitable that a water-soluble, hygroscopic, and corrosive residue would be produced.
ろう付は後にこれら腐食性を有する残漬を洗い流す事は
、面倒で製品の価格を高くする原因ともなる為、好まし
くない。It is not desirable to wash away these corrosive residues after brazing because it is troublesome and increases the price of the product.
本発明のアルミニウム材ろう付は用フラックスは、上述
の様な不都合を解消するものである。The flux for brazing aluminum materials of the present invention eliminates the above-mentioned disadvantages.

られない事が解った。When this flux was used for brazing in the same manner as in the case of the product of the present invention, plate material 1.2 was not brazed, indicating that sufficient brazing strength could not be achieved with this flux. I understand.
以上、本発明品Ｔｆｉ類と比較品３ ｆｉ類とに就しＡ
て行なった実験の結果を、別表に示した。As mentioned above, A for the present invention product Tfi class and comparative product 3 fi class.
The results of the experiments conducted are shown in the attached table.
Ｃ１発明の効果
本発明のアルミニウム材ろう付用フラックスは、以上に
述べた通り構成され、使用されるので、アルミニウム材
製の部品同士のろう付けを強固に行なう事が出来、しか
もろう付は後に腐食性を有する残漬が生じない為、強固
で耐久性のあるアルミニウム材製品を得る事が出来る。C1 Effects of the Invention The flux for brazing aluminum materials of the present invention is configured and used as described above, so parts made of aluminum materials can be firmly brazed together, and brazing can be done later. Since no corrosive residue is produced, strong and durable aluminum products can be obtained.
