Bulk Fe_80-xCu_xP₁₃C₇ (x = 0, 0.1, 0.3 and 0.6 at.%) amorphous alloys were successfully fabricated utilizing the combining fluxing treatment and J-quenching technique. The influence of Cu content on the crystallization characteristic temperatures and primary crystallization phase evolution, glass formation ability, mechanical and soft magnetic properties of Fe-Cu-C-P BMGs have been systematically investigated. Additionally, the proper addition of Cu content can significantly improve the compression plasticity of present Fe-Cu-C-P bulk glassy alloys, and the Fe_79.4Cu_0.6P₁₃C₇ bulk glassy rod exhibits an excellent plasticity of 5% as well as a high fracture strength (over 2700 MPa). Then, the multiple effects of annealed Fe_80-xCu_xP₁₃C₇ BMGs on mechanical properties and soft magnetic property have been investigated. More importantly, Fe_79.4Cu_0.6P₁₃C₇ BMG annealed at T_g-30 K for half an hour exhibits excellent soft magnetic properties with relatively high saturation magnetization of 1.5 T, and mechanical properties with the fracture strength of 3280 MPa and plastic strain of 4%.
