ABSTRACT:
A Co—Cr—Mo-based alloy includes: 63 mass %≦Co<68 mass %; 15 mass %≦Cr<26 mass %; 10 mass %≦Mo<19 mass %; and the balance of inevitable impurities, wherein the total amount of Cr and Mo is from 32 mass % to 37%. The mass magnetic susceptibility of the alloy is 7×4π·10−9m3/kg or less at room temperature, and the Vickers hardness number (Hv) of the alloy is 400 or more.
