The invention discloses a centimeter-level high-strength iron-based bulk amorphous alloy and a new copper mold casting method; the amorphous alloy molecular formula is Fe_44-xCo₆Cr₁₅Mo₁₄C₁₅B₆Tm_x, where x represents the atomic percentage of the corresponding alloy element, and satisfies 0≤x ≤6; The new copper mold casting method is to obtain non-gold alloy ingots by arc melting on a copper mold with cooling water and direct cooling under negative pressure; compared with the prior art, the remarkable feature of the alloy of the present invention is that it has high non-gold alloy ingots. The crystal forming ability has high strength and hardness at the same time. The maximum critical diameter of 10mm can be reached by traditional casting, the strength is up to 4295Mpa, and the Vickers hardness is up to 1220Hv. At the same time, the alloy of the present invention has obvious spin glass behavior at low temperature; The inventive preparation method has a low cooling rate, breaks away from the limitation of the mold diameter, and can directly obtain amorphous alloy ingots, reducing costs, and its maximum diameter is 16.52mm; this preparation method can more accurately determine the amorphous formation of bulk amorphous alloys ability.
