Or, according to the AgCu alloy material, Si, Ti, Zr,
From 0.01 to 1% by weight of one or more rare earth elements such as Hf, Y, Sm, Eu, and Er in total, mechanical strength is improved, and hardness is particularly sufficient.
If it is less than 1% by weight, the improvement effect cannot be expected, and if it exceeds 1% by weight, the high quality or characteristics of Ag or AgCu alloy is impaired. In addition, Si, Ti, Zr, Hf, Y, S
Rare earth elements such as m, Eu, and Er are not limited to one kind, and two or more kinds can also similarly have an improving effect. In addition to Y, Sm, Eu, Er, Sc, La, C

The rare earth elements of m, Yb, and Lu also have the similar improvement effect. The Ag or AgCu alloy material for ornaments of the present invention comprises Ag or AgCu alloy and Si, Ti, Z.
It is presumed that the mechanical strength is further improved because the difference in the crystal structure from the rare earth element such as r, Hf, Y, Sm, Eu, and Er is strongly connected strongly. Further, the deoxidizing action of Si, Ti, Zr, Hf, and the rare earth element improves the flow of molten metal during casting, and it is a good material without material defects such as pinholes.

Cu, 10% by weight each containing Ti, Zr, Hf, Y, Sm, E
A material containing 4% by weight each of u and Er was used as a master alloy and was melt-cast in a high-frequency vacuum melting furnace to a predetermined content of 0.
The composition was 01% by weight, 0.2% by weight, and 1% by weight, and then a wire rod having a wire diameter of 0.5 mm and a wire drawing rate of 90% was used. As a conventional example, pure Ag and AgCu having a purity of 99.9%
7.5% by weight (without Si, Ti, Zr, Hf, and rare earth elements) is melted, cast, and drawn to a wire diameter of 90%
A 0.5 mm wire rod was used. However, it was confirmed that, in the examples, the material has a good flow of molten metal during casting, good workability, and good mechanical strength without material defects such as pinholes, as compared with the conventional example. As a result of hardness measurement and processing into a necklace, Hv90 to 100 was obtained in Conventional Example Ag. In the conventional example AgCu 7.5 wt%, Hv 140
It was ~ 150. In the examples, as shown in Table 1, it was an extremely hard Ag or AgCu alloy material.
