PROBLEM TO BE SOLVED: To provide an Ni amorphous alloy excellent in glass forming performance, workability and mechanical properties. SOLUTION: This alloy has a compsn. represented by the formula: N100-a-b-cNba (Zr, Ti, Hf)b (Co, Fe, Cu, Pd)c [where (a) to (c) in the formula denote atomic ratios, respectively, a=10 to 28, b=10 to 28, c=0 to 15, a+b=35 to 42 and a+b+c=35 to 50, and the balance Ni with inevitable impurities] and contains >=50 vol.% amorphous phase combining a supercooling liq. region of >=30K and a glass transition temp. of >=800K. The alloy has >=0.5 mm2 cross section and >=2,500 MPa compressive strength.
