An iron-based bulk amorphous alloy having chrome/molybdenum is provided to reduce the manufacturing cost by adding Fe of 60atom percent or above in forming a bulk amorphous alloy. An iron-based bulk amorphous alloy having chrome/molybdenum contains Cr of 4 ± 0.1 atom percent, Mo of 4 ± 0.1 atom percent, Si of 1 ± 0.1 atom percent, Nb of 2 ± 0.1 atom percent, C of 7 ± 0.1 atom percent, B 8 ± 0.1 atom percent, balance of Fe and impurity. In order to obtain Fe-based alloy having optimum Cr/Mo the composition of Cr is adjusted in a range of 3 to 17 percent, and the composition of Mo is adjusted into 1 to 13 percent. When Cr has a composition of 12 atom percent and Mo has a composition of 2 atom percent, the Fe-based alloy achieves optimum mechanical property. |
