N2 - The bulk Fe-Al-Ga-P-C-B-Si glassy alloy in a ringed form with the outer diameter of 10 mm, the inner diameter of 6 mm and the thickness of 1 mm was prepared by copper mold casting. This bulk alloy sample was composed of a single amorphous phase and had a supercooled liquid region of 59 K, which was the same as that of the melt-spun ribbon. The saturation magnetization, the coercivity and the maximum permeability of the bulk amorphous alloy sample in as-made state were about 1.2 T, 2.2 A/m and 110 000, respectively. These good soft magnetic properties of the bulk sample depend upon its high structural homogeneity based on large glass forming ability. In addition, the core loss for the Fe-based bulk amorphous alloy is lower than that of a nonoriented 3.5% Si steel in as-made state at the frequency of 50-60 Hz. It is, therefore, concluded that the Fe-Al-Ga-P-C-B-Si glassy alloy will be one of the useful industrial materials.
