Co-Cr-Mo-BASED FINE WIRE, MANUFACTURING METHOD THEREFOR, AND SHEET-SHAPED BODY, TUBE-SHAPED BODY, STRANDED WIRE AND CABLE FORMED OF THE FINE FIRE

摘要

PROBLEM TO BE SOLVED: To provide a Co-Cr-Mo-based fine wire superior in biocompatibility, corrosion resistance, abrasion resistance, workability and flexibility, to provide a manufacturing method therefor, and to provide a sheet-shaped body or the like formed of the fine wire.

SOLUTION: The fine wire comprises 26-31 mass% Cr, 8-16 mass% Mo and the balance Co with unavoidable impurities; has a diameter of 200 μm or smaller; has a circularity (minor diameter/major diameter) of a cross section of 0.6 or more; and has a uniform inner structure having a ratio of a concentration in a high Mo phase to that in a low Mo phase in an amount of 1.8 or less.
