The new Mg-Zn-Y-Nd-Ca magnesium alloys are used as the research object, and its components are designed to evaluate the cytotoxicity of magnesium alloys with different component elements. The cytotoxicity test of fibroblast L-929 and osteoblasts MC3T3-E1 indicates that Mg-Zn-Y-Nd-Ca, as a biodegradable material, can meet the needs of cytotoxicity and promote the proliferation of osteoblasts MC3T3-E1. The mechanical properties test shows that the new magnesium alloys have good mechanical property, tensile strength is about 290Mpa and elongation can reach 15%.
