METAL ULTRAFINE WIRE, PROCESS FOR PRODUCTION OF METAL ULTRAFINE WIRE, AND MESH WIRE NETTING USING METAL ULTRAFINE WIRE

摘要

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 30µm 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 Fe and unavoidable impurities.  The metal ultrafine wire exhibits a tensile strength (ss) of 1000 to 1500MPa and an elongation (E) of 20% or above.
