(Industrial Application Field) The present invention relates to a composite material for decorative items, particularly a composite material for decorative items such as eyeglass frames, tie pins, and watch bands, which has spring properties, is lightweight, and has excellent brazing properties. Regarding the manufacturing method. (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. On the other hand, precious metals used as materials for decorative articles have poor spring properties and are also disadvantageous in terms of weight reduction. Therefore, research and development efforts are underway to compensate for these shortcomings, and the application of composite materials made of Ti or Ti alloys clad with precious metals to ornaments is being considered. By the way, for decorative items, after assembling parts with complex shapes,
In many cases, the final product is made by brazing, so it is essential for materials for decorative items to have excellent brazing properties.In particular, materials for decorative items such as eyeglass frames, tie clips, and hairpins are soldered with wax. Not only is it required to have excellent attachment properties, but it is also required to have excellent spring properties. However, since the conventional decorative composite material 1 shown in FIG.
It is made by cladding the outer sheath metal 3 of K20 alloy containing 8.0% Ag and 8.6% Cu by weight, and when this is processed into a rim wire 4 for eyeglass frames and brazed as shown in Fig. 6, when brazing Since it is exposed to high temperatures of 600 to 900℃, the Au in the outer sheath metal 3 on the brazed part 5 side becomes Ti.
This results in the formation of a very brittle intermetallic compound 6. As a result, the intermetallic compound 6 causes the outer sheath metal 3 and the core material 2 to separate, making it unusable. Further, the decorative composite material 1 has an outer covering metal 3.
K20 alloy has poor spring properties, and Ti, which is the core material 2, also has poor spring properties. In order to improve the spring properties of Ti,
Various Ti alloys have been developed that are alloyed with various metals, but these lack the workability required for materials for decorative items. (Object of the Invention) The present invention has been made to solve the above problems, and provides a composite material for decorative items that is lightweight, has excellent brazing properties, and has good workability and spring properties, and a method for manufacturing the same. The purpose is to (Structure of the Invention) The composite material for decorative items of the present invention has Ti or a Ti alloy as a core material, and Ag, an Ag-Cu alloy, or an Ag-Pd alloy is interposed between the core material and a Ni alloy containing 5 to 60% by weight of Cu. is clad as an intermediate material, and a noble metal alloy is further clad as an outer covering metal. The method for producing a composite material for decorative articles of the present invention includes Ti
Or on the outer circumferential surface of Ti alloy wire, the outer circumferential surface and inner circumferential surface of Ni alloy pipe, the inner circumferential surface of noble metal alloy pipe,
After applying Au plating, Ag plating and Ni plating,
This method is characterized by sequentially fitting a Ni alloy pipe and a precious metal alloy pipe onto a Ti or Ti alloy wire rod, and then performing plastic working such as extrusion or drawing to clad the wire. In the composite material for ornaments having the above structure, no brittle layer is formed during heating during brazing, and peeling from the interface is prevented. In addition, the intermediate material Ni-
Cu alloy has high spring properties, making it ideal as a decorative material that requires spring properties. Cu content of intermediate Ni-Cu alloy: 5 to 60% by weight
The reason for this limitation is that if the content is less than 5% by weight, the spring properties will be insufficient, and if it exceeds 60% by weight, 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, since Ag, Ag-Cu alloy, or Ag-Pd alloy is interposed between the core material and the intermediate material, thermal distortion during heat treatment is alleviated, and the core material and the intermediate material This results in high bonding strength. Furthermore, in the above method for manufacturing composite materials for decorative items, the outer circumferential surface of the Ti or Ti alloy wire, the outer circumferential surface and inner circumferential surface of the Ni alloy pipe, and the inner circumferential surface of the precious metal alloy pipe are plated with Au, Ag or The reason for Ni plating is that it prevents oxidation during the manufacturing process and simplifies the process. (Example) A specific example of the present invention will be described together with a conventional example. The decorative composite material 10 shown in FIG.
2.73mm Ti is used as the core material 11, and 0.10mm thick Ni-
Cu10wt% alloy is clad as intermediate material 12, and Ag-Pd30 with a thickness of 0.034 mm and an outer diameter of 3.0 mm is used.
% alloy is clad as the jacket metal 13, and the thickness ratio thereof is 40:3:1. These were manufactured by applying 10μ of Ag plating and 2μ of Au plating to the outer peripheral surface of a Ti cylinder with a diameter of 45.5mm.
10μ Ni plating is applied to the outer and inner circumferential surfaces of a Ni-Cu 10 weight% alloy pipe with an inner diameter of 45.6 mm and an outer diameter of 49.0 mm, and an inner circumferential surface of an Ag-Pd 30 weight percent alloy pipe with an inner diameter of 49.1 mm and an outer diameter of 50.2 mm. After applying Ni plating of 10 μm to the Ti cylinder, a Ni-Cu 10% alloy pipe and a Ag-Pd 30% alloy pipe were sequentially fitted onto the Ti columnar material, and then extrusion was performed to clad them, and then drawn. It has been processed to have the dimensions described above. The ornamental composite material 10' shown in FIG.
2.32mm Ti is used as the core material 11, and Ag with a thickness of 3μ is attached to this.
- Cu10wt% alloy layer 14 is interposed and the thickness is 0.34mm
Ni-Cu35% by weight alloy is clad as intermediate material 12, and K20 with a thickness of 0.034 mm and an outer diameter of 3.07 mm is used.
Even when the alloy is used as the jacket metal 13, the thickness ratio thereof is 34:0.1:10:1. These are made by applying Ag plating of 5μ and Au plating of 2μ to the outer peripheral surface of a Ti wire with a diameter of 37.8mm, and an inner diameter of 37.9mm.
mm, outer diameter 49.0 mm, Ni-Cu35 weight% alloy pipe with 10μ Ni plating on the outer and inner circumferential surfaces, inner diameter 49.1
After applying 5μ of Ni plating to the inner peripheral surface of a K20 alloy pipe with an outer diameter of 50.1 mm, a thin-walled pipe with a thickness of 0.05 mm made of 10 weight % Ag-Cu is interposed on a Ti wire, and a Ni-Cu 35 weight % alloy pipe is inserted. A K20 alloy pipe was fitted into this, and then extrusion was performed to clad these, and further drawing was performed to obtain the dimensions described above. On the other hand, an example of the conventional composite material 1 for decorative items as shown in FIG. clad, these thickness ratios are
The ratio is 105:1. These fabrications were made using a Ti cylindrical material with a diameter of 49.5 mm, an inner diameter of 49.6 mm, and an outer diameter of 49.6 mm.
After fitting a 50.1 mm K20 gold alloy pipe, it was extruded and clad, and then drawn to the above dimensions. The specific gravity and tensile strength of the composite materials for ornaments of the first example, the second example, and the conventional example manufactured as described above were measured, and the composite materials for ornaments of the first example and the second example were further evaluated. As shown in Figures 3 and 4, the rim wires 15 and 15' for eyeglass frames are processed and brazed.
A conventional composite material for decorative items was processed into a rim wire 4 for an eyeglass frame as shown in FIG. 6, brazed, and the brazing strength was measured and quality inspected.
The results shown in the table below were obtained.
