Abstract
An amorphous metal alloy having high tensile strength and high electrical resistivity is provided. The amorphous metal alloy has the following chemical composition, in atomic percent: (Co1-aFea)100-b-c-dCrbTcXd, where, T is at least one element selected from the group consisting of Mn, Mo, and V; X is at least one element selected from the group consisting of B, Si and P, and a, b, c and d satisfy the formulas of: 0≦a≦100, 4≦b≦25, 0≦c≦40, 15≦d≦35, respectively. An amorphous metal alloy is obtained having a tensile strength greater than 3500 MPa, and an electrical resistivity greater than 145 μΩ-cm.
