った。However, this silver-#1I (5-15% by weight) alloy is
Heat treatments such as annealing and brazing that are repeated several times during the production of decorative items tend to coarsen the crystal grains of the alloy, resulting in the finished surface becoming less shiny and becoming too soft, causing scratches. In addition, most heat treatments such as annealing and brazing are performed in the atmosphere, and copper in copper alloys is easily oxidized, so heat treatment causes copper oxide to form on the surface of the material. A film is formed. Since this oxide film is strong, it must be removed mechanically or by chemical treatment such as pickling. Also, since the oxide film is difficult to remove uniformly, it ultimately affects the quality of the product. This causes uneven coloring.Furthermore, during brazing work, there are problems such as the brazing parts become oxidized, copper oxide makes it difficult to braze, and brazing tends to be defective.
(発明の目的)

とを目的とするものである。(Object of the Invention) The present invention was made to solve the problems of the above-mentioned silver material for decorative items made of a silver-copper alloy. The object of the present invention is to provide a silver material for decorative items that does not cause corrosion, has high hardness, does not form an oxide film, and does not cause defects during brazing.
(問題点を解決するための手段)
本発明の装飾品用銀材料は、眼中に酸化マンガンと酸化
錫を0.5〜15重量%を均一微細に分散して成るもの
である。(Means for Solving the Problems) The silver material for ornaments of the present invention is made by uniformly and finely dispersing 0.5 to 15% by weight of manganese oxide and tin oxide in the eye.
本発明の装飾品用銀材料に於いて、眼中に酸化マンガン

一層良くなるが、塑性加工しにくくなり、材料が割れた
り、成形しにくくなるからである。In the silver material for ornaments of the present invention, the reason why 0.5 to 15% by weight of manganese oxide and tin oxide are dispersed in the eye is 0.5 to 15% by weight.
If it is less than 15% by weight, coarsening of crystal grains during heat treatment such as annealing and brazing cannot be suppressed, and the hardness is low.
If the weight exceeds 1%, the effect of grain refinement and hardness will be better, but it will become difficult to plastically work, the material will crack, and it will become difficult to mold.

い。(Function) In the silver material for ornaments of the present invention having the above structure, the manganese and tin oxides uniformly and finely dispersed in the eye act as crystal grain refining agents during heat treatments such as annealing and brazing. This prevents crystal grains from becoming coarse due to heat treatment and maintains hardness higher than that of silver-copper alloys, making it easier to produce a gloss in the final finish and resist scratches. In addition, since manganese and tin oxides are already dispersed in the eye, an oxide film will not be formed during heat treatment in the atmosphere such as annealing and brazing, so unlike in the case of copper alloys. There is no need to remove the oxide film, and there is no uneven coloring of the product.Furthermore, brazing parts do not oxidize, so brazing is easier to work with, and brazing is less likely to cause defects.

This makes it possible to produce shiny, scratch-resistant decorative items. In addition, the silver material for decorative items of the present invention does not form an oxide film during heat treatment such as annealing or brazing, so there is no need to remove the oxide film, and decorative items without uneven color can be manufactured. I can do it. Furthermore, since the silver material for ornaments of the present invention does not oxidize during brazing, the brazing process is easy, the brazing process is free from defects, and the brazing process allows the manufacture of highly strong decorative items. It has excellent effects such as being able to.
