Patent ID: 7857916

Claim:
A Co—Cr—Mo alloy fine wire for biomaterials, consisting of: 26 to 31 weight % of Cr; more than 8 weight % to 16 weight % of Mo; and the remainder of Co and inevitable impurities, the alloy being Ni-free; the wire having a diameter of 200 micrometers or less and a degree of roundness (minor diameter/major diameter) of lateral cross section of 0.6 or more, and a uniform structure with a concentration ratio of maximum Mo concentration phase with respect to minimum Mo concentration phase of 1.8 or less when Mo concentration is measured at one or more arbitrarily selected cross sections of said fine wire, wherein the wire was obtained by injecting the melted Co—Cr—Mo alloy from a nozzle to form a melted alloy jet and cooling and solidifying the melted alloy jet.
