Embodiment 1

[0107] The wire rods (Examples A1-A6) made of the six Co-based alloy materials shown in Table 1, which were produced by the vacuum double melting method, were repeatedly subjected to cold drawing and heat treatment, and the diameter was reduced to the wire diameter Afterwards, it is heat-treated at a temperature of 1150°C to obtain a soft thin wire as a material. The wire drawing described above was performed by a sliding type wet wire drawing using a diamond die. In this series of material processing stages, there were no major problems such as wire breakage and die scratches, and they were processed well at an intermediate processing rate of 70-98%, especially the alloy wires of samples A1-A4 were good. In addition, in the microscopic examination of its cross section, no special harmful inclusions and structural defects were found.

[0108] On the other hand, in Comparative Examples B1 to B3, SUS304, 304N, and 316 materials conventionally used as high-strength ultra-fine wir...

Embodiment 2

[0121] In above-mentioned embodiment A1, will be thinned into One end of the hard thin wire is annealed at a temperature of 1150°C to make a soft wire, and then drawn to 40 μm and annealed at a temperature of 1110°C, and the final cold drawing process is passed through the above-mentioned sliding type machine to reduce the diameter to 19 μm, and then heat treatment in the range of the above-mentioned B value of 120 to 130 to obtain the specified ultra-fine wire. As comparison objects, Comparative Examples B1 and B2 were used. Their processing ratios were lower than in Example A1, and were performed at 77%. In order to observe the influence at this time, the final heat treatment was similarly performed at a temperature of 1050° C.×100 m / min. The result is as Figure 5 shown.

Embodiment 3

[0124] In order to observe the influence of the ambient gas in the final heat treatment of Example A2 above on the characteristics, the same heat treatment was performed using Ar gas, and various characteristics were investigated. All the characteristics were within the range of the standard deviation, and no significant difference was observed.

Abstract

The present invention provides a metal ultrafine wire which is excellent in workability in weaving and can bring about high strength, higher precision, and a longer life; a process for production thereof; and a mesh wire netting for use in screen printing which is made using the ultrafine wire. The metal ultrafine wire has a diameter (d) of 30[mu]m or smaller, and consists of a Co-base alloy which contains by mass C: 0.005 to 0.3%, Si: <=2.0%, Mn: <=2.0%, Ni: 5 to 38%, Cr: 15 to 28%, and Co: 35 to 58%, and further contains either Mo: 0.4 to 12% or W: 1 to 16% with the balance consisting of Feand unavoidable impurities. The metal ultrafine wire exhibits a tensile strength ([Sigma]s) of 1000 to 1500MPa and an elongation (E) of 20% or above.

Description

technical field [0001] The present invention relates to a high-strength, high-precision, and excellent weaving workability metal ultra-fine wire suitable for use as a high-mesh (HIGHMESH) metal mesh such as screen printing and filtering, and a method for manufacturing an ultra-fine metal wire. Mesh metal mesh using metal extra-fine wire. Background technique [0002] Conventionally, expanded metal meshes have been used in various applications, for example, for screen printing and filters. In addition, its quality has been improved by high strength, high precision, and long life in recent technological innovations. In addition, various mesh metal meshes suitable for purposes and applications are being developed. Recently, as screen printing applications, for example, printing applications on glass, printed circuit boards, and the like, there is a tendency to further increase the size of plasma display devices. In addition, as a filter mesh used under severe conditions, the...
