ある。That is, since the Zn content is small within the range of 4 to 10 wt.%, the brazing temperature range of this brazing filler metal is close to the solidus temperature of the aluminum member. Therefore, it is necessary to braze at a high temperature close to the solidus temperature of the aluminum member, which may cause the aluminum member to melt or deform.
先行技術２には１次に述べるような問題がある。Prior art 2 has the following problems as described in the first section.

管理する必要がある。The melting point of JIS 2000 series aluminum members, which have been widely used in recent years, is as low as approximately 520°C. Therefore, even with the brazing filler metal of Prior Art 2, when brazing aluminum members with such a low melting point, the brazing temperature must be lowered. It needs to be strictly controlled.
このために、より低い温度でろう付けすることができ、

We conducted extensive research in order to develop a brazing material that can be efficiently brazed and produce high-quality joints. As a result, a brazing filler metal whose brazing temperature is approximately 380 to 480°C can satisfy the above-mentioned conditions, and such a brazing filler metal has a component composition of 85 to 97 wt.% zinc.

この発明のろう材の化学成分組成を、上述した範囲内に
限定した理由について、以下に述べる。The reason why the chemical composition of the brazing filler metal of this invention is limited to the above-mentioned range will be described below.
（１）亜鉛（Ｚｎ） 亜鉛には、ろう材の融点を下げる作用がある。(1) Zinc (Zn) Zinc has the effect of lowering the melting point of the brazing filler metal.

下げることができない、一方、亜鉛含有量が９７ｗｔ、
％を超えると、融解したろう材によってアルミニウム部
材が侵食される問題が生ずる。However, when the zinc content is less than 85 wt.%, J
The brazing temperature cannot be lowered below 450°C so that low melting point aluminum parts, such as those made of IS 2000 series aluminum alloys, can be brazed without melting or deformation. 97wt,
%, the problem arises that the aluminum member is eroded by the molten brazing filler metal.
従って、亜鉛含有量は、８５から９７ｗｔ、％の範囲内
に、そして、より好ましくは、９０から９５ｗｔ、％の
範囲内に限定すべきである。Therefore, the zinc content should be limited to within the range of 85 to 97 wt.%, and more preferably within the range of 90 to 95 wt.%.
（２）ケイ素（Ｓｉ） 、銅（Ｃｕ）
ケイ素および銅には、ろう材の表面に生ずる酸化皮膜を
ポーラス状にすると共に、これを薄く保って破壊されや
すくなし、そして、ろう材の電気化学的性質を責となし
てその腐食を抑制し、更に、融解したろう材の流動性を
向上させる作用がある。(2) Silicon (Si), Copper (Cu) Silicon and copper are used to make the oxide film that forms on the surface of the brazing material porous, to keep it thin so that it is not easily destroyed, and to make the electrolytic film of the brazing material porous. It also has the effect of suppressing corrosion due to its chemical properties and improving the fluidity of the molten brazing filler metal.
しかしながら、ケイ素の含有量が０，３ｗｔ、％未満、
または、銅の含有量が２ｗｔ、％未満では、上述した作
用に所望の効果が得られない、一方、ケイ素の含有量が
５ｗｔ、％を超えても、より以上の効果は得られず、逆
に、ろう材の加工性が劣化する問題が生ずる。また、銅
の含有量がＬｏｕｔ、％を超えると。However, if the silicon content is less than 0.3wt%,
Alternatively, if the copper content is less than 2 wt.%, the desired effects described above cannot be obtained, while even if the silicon content exceeds 5 wt.%, no further effect can be obtained; Another problem arises in that the workability of the brazing filler metal deteriorates. Moreover, when the copper content exceeds Lout,%.
ろう材の融点が上昇する問題が生ずる。A problem arises in that the melting point of the brazing filler metal increases.
従って、ケイ素の含有量は、０．３から５ｗｔ、％の範
囲内に、そして、銅の含有量は、２から１０ｗｔ、％の
範囲内に限定すべきである。Therefore, the silicon content should be limited to within the range of 0.3 to 5 wt.%, and the copper content within the range of 2 to 10 wt.%.
（３）ケイ素含有量のアルミニウム含有量に対する比

/A circle affects the fluidity of the melted brazing filler metal. Therefore, in this invention, it is desirable to keep the Si/AQ ratio within the range of 0.05 to 0.12.
If the ratio is less than 0.05, the fluidity of the melted brazing filler metal cannot be sufficiently improved; on the other hand, if the Si/AΩ ratio is 0.
．． If it exceeds 12, on the contrary, the fluidity of the melted brazing filler metal decreases.
