To produce an amorphous alloy contg. no beryllium.

In this amorphous alloy, dimensions in all directions are regulated to ≥1mm. In this case, it contains at least five elements essentially consisting of metal selected from the groups of 45 to 65at% zirconium, 5 to 15at% aluminum and zinc, metal selected from the groups of 4 to 7.5% titanium and niobium, and the balance metal selected from the groups of copper, nickel, cobalt and ≤10at% iron, and in which the ratio of copper to nickel and/or cobalt is regulated to 1:2 to 2:1.
