A bulk-glass forming Ni-Cr-Nb-P-B alloy is provided. The alloy includes Ni(100-a-b-c-d)CraTabPcBd, where the atomic percent a is between 3 and 11, the atomic percent b is between 1.75 and 4, the atomic percent c is between 14 and 17.5, and the atomic percent d is between 2.5 and 5. The alloy is capable of forming a metallic glass having a lateral dimension of at least 3 mm. L'invention concerne un alliage de Ni-Cr-Nb-P-B de formation de verre massique. L'alliage comprend Ni(100-a-b-c-d)CraTabPcBd, où le pourcentage atomique a est entre 3 et 11, le pourcentage atomique b est entre 1,75 et 4, le pourcentage atomique c est entre 14 et 17,5 et le pourcentage atomique d est entre 2,5 et 5. L'alliage est apte à former un verre métallique ayant une dimension latérale d'au moins 3 mm.
