この発明は炭素鋼及び銅被覆炭素鋼のろう付のために雰
囲気炉内で使用するろう付用銅合金（以下青銅ろうと称
す）に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brazing copper alloy (hereinafter referred to as bronze solder) used in an atmospheric furnace for brazing carbon steel and copper-coated carbon steel.

れ、また、ろうとしては銅ろうが多く用いられている。In recent years, furnace brazing using a protective gas has become popular in brazing work, and the protective gas used is exothermic gas DX (DX), which has the composition shown in Table 1 below.
Gas) or gas mixed with decomposed ammonia AX (decomposed ammonia gas) at a temperature of about 8° C. is used, and copper solder is often used as the solder.
表

の提供が望まれていた。It has been desired to provide a solder that is inexpensive and can be applied to furnace brazing work.
この目的に適合するものとして、下記第二表に３５示す
ような組成をもつＬ−ＳｎＢ２６及びＬ一ＳｎＢ２１２

言えなかつた。L-SnB26 and L-SnB212 having compositions as shown in Table 2 below are suitable for this purpose.
Two types of bronze solders are specified in DIN 8513, but both are made by undergoing phosphorus deoxidation treatment.
It could not necessarily be said that the tensile strength and shear strength of the brazing filler metal itself were sufficient,40 and it could not be said that the drawability was also sufficient.

ないと言われている。In view of the above, this invention was proposed to improve the drawbacks of conventional materials, and has a weight ratio of 0.1 to 0.4% manganese and 8 to 110% tin! ), with the remainder essentially consisting of copper, and the tensile strength of the brazing filler metal itself is higher than that of conventional bronze solders that have been subjected to phosphorus deoxidation treatment.
The object of the present invention is to provide a bronze solder which has increased shear strength, increased drawability, and facilitates wire workability. Examples of the present invention will be described below. Phosphorus is usually used as a deoxidizing agent in the melting of bronze solder.
0.1 to 0.8 manganese as a deoxidizer instead of phosphorus
% increases the tensile strength and elongation of the bronze solder itself, and in the case of bronze solders with a manganese content of less than a few percent, it is necessary to maintain the relative tensile strength even at high temperatures. It is said.
青銅ろう中のマンガン含有量が０．４％以上になると、
フラツクスなしでろう付作業を行なう場合には、溶解し
たろうの表面に緑色の酸化被膜を生じるため使用には不
適当である。When the manganese content in bronze solder exceeds 0.4%,
If brazing is carried out without flux, a green oxide film will form on the surface of the melted solder, making it unsuitable for use.

しくない。Furthermore, as the manganese content increases, the thickness of the oxide film increases, and if it exceeds 1%, the wax will not dissolve, which is not preferable. In addition, as the content of tin increases, the drawability of the bronze solder itself decreases and it becomes brittle, making wire rod processing gradually difficult, and if the tin content exceeds 11%, wire rod processing becomes impossible. On the other hand, if the content is less than 8 (:Ff), the liquidus temperature becomes high, which is not preferable.

銅ろうの液相線温度は９９０〜１０３０℃である。Therefore, the bronze solder requires 0.4% or less of manganese and 8 to 11% of tin by weight, and the liquidus temperature of this bronze solder is 990 to 1030°C.
次に、この発明の実施例をあげ、同時に従来のリンによ
り脱酸処理を施こした青銅ろうとの比較ろう付試験の結
果を下記第三表〜第五表に示す。Next, examples of the present invention will be given, and at the same time, the results of a comparative brazing test with a conventional bronze solder which has been deoxidized with phosphorus are shown in Tables 3 to 5 below.
ただし、青銅ろうはいずれも１φに線材加工されたもの

度が上昇している。However, the bronze solder used was a wire rod processed to 1φ, and the mixed processing gas listed in Table 1 above was used as the protective gas. As is clear from the above results, the strength of the bronze solder of this invention that has been deoxidized with manganese is higher than that of the bronze solder that has been deoxidized with phosphorus.
この発明は上記のように、重量比でマンガン０．１〜０

の優れた効果がある。As mentioned above, this invention has a weight ratio of 0.1 to 0 manganese.
．． Since the bronze solder composition contains 4% tin and 8-11% tin, the tensile strength and shear strength of the bronze solder itself are further increased, and the drawability is also increased, resulting in good wire workability, and even in high temperature conditions. It has excellent effects such as almost no change in tensile strength.
