がある。 Generally, materials such as silver solder, copper solder, and nickel solder are often used as brazing alloys used in metal brazing work. Among these, silver solder is widely used because it has characteristics such as a low melting point and excellent flowability. However, since silver solder contains many components with high vapor pressure, such as cadmium and zinc, during vacuum brazing work, these components with high vapor pressure evaporate and contaminate the inside of the vacuum furnace, causing the operation of the vacuum furnace to be interrupted. It is unsuitable for vacuum brazing work because it has drawbacks such as inhibiting the soldering process and deteriorating the gloss of the brazed product due to the generated metal vapor. Furthermore, there are other disadvantages such as the fact that silver, the main component, is expensive. On the other hand, copper solder has a high melting point of 1000° C. or higher, so it has poor workability and is not only undesirable from the viewpoint of energy saving, but also often suffers from thermal distortion. Furthermore, although nickel brazing is often used for stainless steel brazing because it has excellent high-temperature strength and corrosion resistance, it has poor workability.
Since it can only be used in the form of powder or paste, the powder or paste solder must be manually applied each time during brazing work, which is disadvantageous in reducing work efficiency.

用ろう合金（第２の発明）である。 The present invention was made in view of the above-mentioned current situation, and its purpose is to reduce the generation of metal vapor during vacuum brazing work, maintain good vacuum furnace operation, and improve gloss. The purpose is to obtain an excellent quality product, which can be processed into thin wires and thin plates, which improves workability, and which is inexpensive for vacuum brazing.Its characteristic is that the weight ratio of manganese is 5 to 20. %, Mitsushi Metal 0.1 to 4%, and the balance copper (first invention);
Manganese 5-20% by weight, Mitsushi Metal 0.1
This is a vacuum brazing brazing alloy (second invention) consisting of ~4% tin, 1~7% tin, and the balance copper.

マンガン含量は５重量％とした。 First, the brazing alloy of the present invention has a melting point lower than that of copper solder in order to prevent the occurrence of thermal distortion and shorten working time, and does not cause undesirable phenomena such as sensitization in stainless steel. As a result of various studies, the main component metal was selected as a copper-manganese alloy with the aim of obtaining a brazing working temperature and having excellent workability to the extent that it could be processed into thin wires and thin plate shapes. That is, since manganese forms a solid solution with copper over the entire range, it can always be processed into a wire or a thin plate, and has excellent workability. The melting point decreases as the content of manganese increases, but at melting points below 900°C, if the material to be brazed is stainless steel during brazing, sensitization occurs, which is undesirable and lowers the melting point to 900°C. ~1000°C, and the manganese content was set to a maximum of 20% by weight in consideration of the excessive generation of manganese vapor in the vacuum furnace. Furthermore, if the manganese content is less than 5% by weight, the melting point becomes too high, which is disadvantageous in terms of energy and workability, so the minimum manganese content is set at 5% by weight.
上記したマンガン含量５〜20重量％の範囲の銅

起することとなる。 The above-mentioned copper-manganese brazing alloy with a manganese content in the range of 5 to 20% by weight is heated in a vacuum furnace (for example,
10 - 3 Torr or less),
Metal vapor is generated from the molten brazing alloy and adheres to the walls of the vacuum furnace, causing poor insulation of the furnace heater and increasing the exhaust load, which not only impairs operation, but also damages the products to be brazed. This may cause adhesion or deterioration of the gloss of the brazed portion, leading to defective products.

好な光沢を保持した製品が得られた。 Therefore, the above-mentioned copper with a manganese content of 5 to 20% by weight
When Mitsushi Metal was added to a manganese alloy, it was discovered that the generation of the metal vapor described above could be prevented. Various experiments were conducted regarding the amount, and it was found that adding less than 0.1% by weight could not suppress the generation of metal vapor, and adding more than 4% by weight made the brazing alloy hard and brittle. Rolling and wire drawing become difficult, resulting in poor workability.
By doing this, the amount of Mitsushi Metal added can be reduced.
When the amount is selected in the range of 0.1 to 4% by weight, the brazing alloy can be processed into a thin wire of 1 mmφ, etc., and it can be easily placed in the brazed part during use, and
Even during brazing work in a vacuum furnace with a vacuum level of 100 -4 Torr or less, the generation of vapor from the brazing alloy could be suppressed, and a product with extremely good gloss was obtained.

が望ましい。 Next, the above-mentioned brazing alloy consisting of 5 to 20% by weight of manganese, 0.1 to 4% by weight of Mitsushi Metal, and the balance copper has a minimum melting point of about 930°C, and if it is necessary to further lower the melting point, the manganese content should be increased. What can be achieved by this method is as described above, but in this case, in the vacuum brazing operation, the generation of metal vapor increases significantly as described above, causing a disadvantage. For this reason, if tin is added without increasing the amount of manganese to adjust the melting point, the brazing temperature can be adjusted without increasing the generation of metal vapor. If the amount added is less than 1% by weight, it will not lower the melting point, and if it is added more than 7% by weight, problems will arise in the workability of the brazing alloy in rolling, wire drawing, etc., which is undesirable. It is desirable to select the amount of addition in the range of 1 to 7% by weight.

良好な製品としてろう付加工し得る。 Since the brazing alloy of the present invention has the above-mentioned composition, it not only has excellent workability because the brazing temperature is between that of copper brazing alloy and silver brazing alloy, but also eliminates the need to use expensive silver. It is economical because brazing strength equivalent to or higher than that can be obtained without any problems. In addition, since it can be processed into wire rods or thin plates, it not only makes it easier to arrange the brazing alloy during brazing work, improving work efficiency, but also because it does not use a binder, it is easier to use the vacuum pump during vacuum brazing work. Load can be reduced. Furthermore, by suppressing the generation of metal vapor during the melting of the brazing alloy in the vacuum brazing process described above, it is possible to prevent metal vapor from adhering to the walls of the vacuum furnace, which can cause electrical insulation defects and exhaust defects. Since the product is not contaminated and the product is not contaminated, the product can always be brazed as a good product without damaging the luster of the product metal.

能であつた。Example A brazing alloy with a weight ratio of 15% manganese, 3% tin, 0.1 to 1% Mitsushi metal, and the balance copper was produced,
The wire was drawn to a diameter of 1 mm. The liquidus temperature of this brazing alloy was approximately 930°C, and vacuum brazing was possible at 970°C.

て観察した処、図面の如き結果を得た。 In order to investigate the amount of metal vapor generated when the above-mentioned brazing alloy melts, a polished SUS304 plate was placed directly above the molten brazing alloy, held at 2 x 10 -4 Torr and 1000°C for 20 minutes, and then vacuumed. After cooling, the glossiness of the polished plate was observed while changing the content of Mitsushi Metal, and the results shown in the drawing were obtained.

It was recognized that the gloss level was significantly improved from around 1.5% or higher, and it was extremely clear that the addition of Mitsushi Metal suppressed the generation of metal vapor. Note that point A in the figure is the glossiness of the polished plate when heat-treated while maintaining the above state without using a brazing alloy.

沢を失うことがない。従つて仕上がり部分の光沢
の高い真空ろう付ができる。 As explained above, according to the first invention, the material contains 5% or more and 15% or less of manganese, 0.1 to 4% of Mitsushi metal, and the balance is copper, and has a weight ratio of 10 -3 to 15%. When brazing is performed in a vacuum atmosphere such as 10 -4 Torr, little metal vapor is generated, so the raw surface of the metal surface to be joined does not lose its luster. Therefore, vacuum brazing with a high gloss finish can be achieved.
また、850〜970℃の温度範囲でろう付けができ

テンレス鋼材の鋭敏化を避けることができ、耐食
性の劣化を引き起こさないとともに、ステンレス
鋼材に熱歪を付加することもない。 In addition, since brazing can be performed in a temperature range of 850 to 970°C, it is possible to avoid sensitization of stainless steel materials when brazing them, thereby preventing deterioration of corrosion resistance and adding thermal strain to stainless steel materials. There's nothing to do.
更に、ミツシユメタルを4.0重量％以下にして
いるので、線引等の加工が容易であり、線状ある
いは薄板状に加工できるので、ろう付部分に均一
に配置することができ、真空ろう付した場合に仕
上がり状態のむらのないろう付けができる効果が
ある。 Furthermore, since Mitsushi Metal is contained at 4.0% by weight or less, it is easy to process such as wire drawing, and it can be processed into a wire or thin plate shape, so it can be placed uniformly in the brazed area, and when vacuum brazed. This has the effect of making it possible to braze with an even finish.
また、第１の発明の組成に更に錫を１〜７％添
加した第２の発明にあつては、金属蒸気発生の増
加を抑えつつ融点降下を実現できる。従つて前記
組成のろう付合金による効果を得た上でより低い
融点でろう付けできる効果がある。 Further, in the second invention, in which 1 to 7% of tin is further added to the composition of the first invention, it is possible to lower the melting point while suppressing an increase in metal vapor generation. Therefore, in addition to obtaining the effects of the brazing alloy having the above composition, it is possible to perform brazing at a lower melting point.
