The Pr55–xAl12+xFe33–yCuy (0 ≤ x ≤ 5, 0 ≤ y ≤ 8) bulk metallic glasses (BMGs) 5 mm in diameter and 100 mm in length were prepared by copper mold suction casting. Hysteresis loops of the Pr55–xAl12+xFe33–yCuy BMGs and the corresponding Pr55Al12Fe30Cu3 crystallized alloy were measured, and the results showed that the Pr55–xAl12+xFe33–yCuy BMGs are hard magnetic, while the completely crystallized Pr55Al12Fe30Cu3 alloy is paramagnetic at room temperature. The thermal behavior and crystallization of the Pr55Al12Fe30Cu3 BMG were studied by differential scanning calorimetry, and the results indicated that the Pr-based BMG has obvious glass transition and a wide supercooled liquid region up to 75 K. The crystallization activation energy for the Pr55Al12Fe30Cu3 BMG is much smaller than that of Zr–Ti–Cu–Ni–Be BMG.
