A (ZrM)-(CuN)-Ni-Al-(RE) amorphous alloy, comprising, by atom percent, 40-65％ of Zr, 18-46％ of Cu, 2-15％ of Ni, 4-15％ of Al, 0.1-3％ of M, 0.05-3％ of N, 0.1-2％ of a rare earth element RE, wherein M is Hf, Ti or Hf+Ti; and N is Ag. The alloy, to which a small amount of Hf, Ti, Ag and RE elements are added on the basis of a Zr-Al-Ni-Cu amorphous alloy, maintains the mechanical properties of the Zr-Al-Ni-Cu amorphous alloy, and has a relatively strong amorphous forming ability, manufacturability and antimicrobial property.
