The FeCoSiBPCCr bulk glassy alloys (BGAs) were prepared by micro-alloying technique. The glass forming ability (GFA) and soft-magnetic properties of the BGAs were examined by X-ray diffraction, TEM, DSC and VSM. The corrosion resistance of the alloys was evaluated by electrochemical measurements and the mechanical properties were tested by macro-compression experiments. The results show that the GFA and corrosion resistance of the FeCoSiBPCCr BGAs are significantly improved with increasing Cr content while the mechanical and magnetic properties exhibit no obvious change. The Fe64.4Co7.6Si7B10P5C2Cr2 BGA rods with diameters up to 5 mm were produced by copper mold casting. These BGAs exhibit excellent corrosion resistance as well as high saturation magnetization of 1.3 T, low coercive force of 3.1 A/m and high fracture strength of more than 3700MPa.
