Summary:PROBLEM TO BE SOLVED: To make an amorphous alloy which can resolve the problem of combining corrosion resistance and electrical conductivity and which exhibits ductility and is useful as a regular industrial material applicable to various fields.SOLUTION: The amorphous alloy contains at least 66 at% of Ni and, for example, 5-25 at% of B as a semimetal. It is preferable that the amorphous alloy contains Mo and Nb as additional major elements, and further contains Cu in some cases. The amorphous alloy does not form any passive film, but exhibits corrosion resistance on the basis of the electrical double layer theory.
