Abstract
A Co-based alloy being useful as a spiral spring, common spring, wire, cable guide, steel belt, build-up material, guide wire, stent, catheter, etc. There is provided a Co-based alloy having a composition of Co—Al binary system containing 3-13% Al loaded with at least one workability enhancing element selected from among 001 to 50% Ni, 0.01 to 40% Fe and 0.01 to 30% Mn and having a lamellar structure wherein f.c.c. structure α-phase and β(B2)-phase are repeated in layers. The lamellar structure is so regulated that the occupancy ratio of the whole structure is 30 vol. % or above and the layer spacing is 100 μm or less. The Co-based alloy may contain at least one optional component selected from among Ga, Cr, V, Ti, Mo, Nb, Zr, W, Ta, Hf, Si, Rh, Pd, Ir, Pt, Au, B, C and P may be added in a total amount of 0.01 to 60%.
