くれが生じたりする等の欠点があった。However, when brazing is performed using this brazing material, the solder surface after brazing becomes rough and uneven. Therefore, when parts brazed using this brazing material are acid-cleaned or plated, the cleaning liquid or the like will penetrate into the irregularities. Since this cleaning solution is difficult to remove completely, it may remain on uneven areas, resulting in disadvantages such as discoloration and corrosion of the brazing metal or blistering of the plating due to the remaining cleaning solution. was there.
（発明の目的）
本発明は上記欠点を解消すべくなされたものであり、ろ
う付後のろう表面の荒れが少なく、凹凸の発生も少ない
パラジウムろう合金を提供せんとするものである。(Objective of the Invention) The present invention has been made in order to eliminate the above-mentioned drawbacks, and aims to provide a palladium brazing alloy that has less roughness on the solder surface after brazing and less occurrence of irregularities.
（問題点を解決するための手段）

成るものである。(Means for solving the problems) The palladium brazing alloy of the present invention contains 15 to 35% by weight of copper,
It consists of 5 to 25% by weight of palladium, 0.001 to 1.0% by weight of at least one of iron, nickel, and cobalt, and the balance silver.

含有させる理由は、ろう付時溶融したろう材の表面張力
を小さくし、それによりろう付後のろう表面の荒れを小
さくし、凹凸の発生を抑制する為である。In the palladium brazing alloy of the present invention, iron, nickel,
The reason for including a small amount of cobalt in the silver-copper-palladium alloy is to reduce the surface tension of the melted brazing filler metal during brazing, thereby reducing the roughness of the solder surface after brazing and reducing the unevenness. This is to suppress the occurrence.
そしてその含有量を０．００１〜１．０重量％と限定し

を汚損し、さらにろう付強度に悪影響を及ぼすからであ
る。The reason why the content is limited to 0.001 to 1.0% by weight is that less than 0.001% by weight suppresses the occurrence of roughness and unevenness on the soldering surface after brazing, and prevents scratches and 1. This is because if the content exceeds 0% by weight, the solder will excessively flow, staining the base material, and having an adverse effect on the brazing strength.
次に本発明のパラジウムろう合金の効果を明瞭ならしめ

The solder surface is less rough after brazing and there are fewer irregularities, so even if the brazed parts are acid-washed or plated, the amount of cleaning liquid that gets into the irregularities of the solder surface is small. As a result, the amount remaining after their removal is small, which has the excellent effect of suppressing discoloration and corrosion of the soldered parts.
