関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to composite materials for decorative items, particularly decorative materials such as eyeglass frames, tie pins, and watch bands that are lightweight, have spring properties, and have excellent brazing properties. Concerning composite materials for products and their manufacturing methods.

（従来技術とその問題点） 近時、各種装飾品に於いて、活動性を高める意味や、装
飾感を高める意味から軽量且つばね特性に優れた装飾品
用素材が要望されている。(Prior Art and its Problems) Recently, there has been a demand for materials for decorative articles that are lightweight and have excellent spring characteristics in order to increase activity and enhance the sense of decoration in various decorative articles.

一方、装飾品用素材としての貴金属はばね特性に劣り、
また軽量化という点でも不利であった。On the other hand, precious metals used as materials for decorative items have poor spring properties.
It was also disadvantageous in terms of weight reduction.

そこでこれらの欠点を補うべく研究開発がなされ、Ｔｉ

Alternatively, the application of composite materials made of Ti alloys clad with precious metals to decorative items is being considered.

特性にも優れていることが要求される。By the way, decorative items are often made into final products by assembling complex-shaped parts and then brazing them. Therefore, it is essential that materials for decorative items have excellent brazing properties, especially for eyeglass frames. Materials for decorative items such as hairpins, tie clips, and hairpins are required to have excellent brazing properties as well as spring properties.

ある。However, since the conventional composite material 1 for ornaments shown in FIG. 3 is lightweight, it is directly coated on the outer periphery of the Ti or Ti alloy core material 2. For example, 83.4% by weight of Au and 8.0% by weight of Ag. , Cu 8.6% by weight is clad with a 20 alloy outer sheath metal 3. When this is processed into a rim wire 4 for an eyeglass frame and brazed as shown in FIG.
Because it is exposed to high temperatures of 0 to 900°C, the Au in the sheath metal 3 forms a very brittle intermetallic compound 6 with Ti on the brazed portion 5 side.
will be formed. As a result, the intermetallic compound 6 causes the outer sheath metal 3 and the core material 2 to separate, making it unusable.

る。Further, in the composite material 1 for decorative articles, the 20 alloy of the outer sheath metal 3 has poor spring properties, and the Ti that is the core material 2 also has poor spring properties. In order to improve the spring properties of Ti, various Ti alloys made by adding various metals have been developed, but these lack the workability required for materials for decorative articles.

It is characterized by being clad as a material and further clad with a noble metal alloy as an outer covering metal.

材のＮｉ−Ｃｕ合金は、ばね性に冨む為、ばね性を要求
される装飾品素材として最適である。In the composite material for ornaments having the above structure, the N1-Cu alloy of the intermediate material and the Ti of the core material or Ti of the Ti alloy diffuse into each other during heating during brazing, and the ternary eutectic material of Ni-Cu-Ti However, since this eutectic 'fJi weave is ductile, it does not form a brittle layer and can prevent peeling from the interface. Furthermore, the Ni-Cu alloy used as the intermediate material has high spring properties and is therefore ideal as a decorative material that requires spring properties.

中間材のＮｉ−Ｃｕ合金のＣｕ含有量を５〜６０重量％
と限定した理由は、５重量％未満ではばね性が不充分で
あり、６０重量％を超えると共晶組織が生ぜず、脆化を
起すからである。The Cu content of the intermediate Ni-Cu alloy is 5 to 60% by weight.
The reason for this limitation is that if it is less than 5% by weight, the spring properties will be insufficient, and if it exceeds 60% by weight, no eutectic structure will be formed and embrittlement will occur.

。The thickness of the core material, intermediate material, and outer covering metal is preferably 10 to 50:3 to 20:1 in order to maintain springiness and lightness.
＼ In addition, in the decorative composite material with the above structure, if a single substance or an alloy of T a % W or Re is interposed between the core material and the intermediate material, excessive diffusion during heat treatment is suppressed, and the core material and the intermediate material are The bonding strength with the material is high, making it more desirable.

The reason for applying Au plating, Ag plating, or Ni plating to the outer peripheral surface of i or Ti alloy wire, the outer peripheral surface and inner peripheral surface of Ni alloy pipe, and the inner peripheral surface of noble metal alloy pipe is to prevent oxidation during the manufacturing process. This is because the process is simplified.
