PCT No. PCT/JP91/01770 Sec. 371 Date Aug. 5, 1993 Sec. 102(e) Date Aug. 5, 1993 PCT Filed Dec. 26, 1991 PCT Pub. No. WO93/13234 PCT Pub. Date Jul. 8, 1993.A vibration-damping alloy having excellent vibration-damping properties, high strength, and excellent workability and weldability has the composition defined by a triangle formed by connecting points A (89% by weight of M, 0.2% by weight of Ni, and 10.8% by weight of Mn), B (75% by weight of M, 15% by weight of Ni, and 10% by weight of Mn), and C (75% by weight of M, 0.2% by weight of Ni, and 24.8% by weight of Mn) in a triangular diagram showing the proportions of M, Ni and Mn in FIG. 1. M consists of Fe and Si, Fe and P, Fe and Al, Fe, Nb and C, Fe and Cu, Fe, Mo and C, or Fe, Ti and C.
