Abstract
The present invention relates to a Cu-based amorphous alloy composition having a chemical composition represented by the following general formula, by atomic %: CuZrAl(M)(M), where a, b, c and d satisfy the formulas of 36≦a≦49, 1≦b≦10, 0≦c≦10, and 0≦d≦5, respectively, and c and d are not zero at the same time, and M, the 4th element added to a ternary alloy of Cu—Zr—Al, is one metal element selected from the group consisting of Nb, Ti, Be and Ag, and M, the 5th element added to the ternary alloy of the Cu—Zr—Al, is one amphoteric element or non-metal element selected from the group consisting of Sn and Si.
