The new Mg-Y-Nd -(La+Ce) -Zr magnesium alloy was taken as the research object to study the types and contents of rare earth alloys. The corrosion properties were studied by scanning electron microscope and electrochemical experiments. The results showed that the new Mg - Y - Nd - (La + Ce) - Zr magnesium alloy had no toxicity to human cells and had ideal corrosion resistance. The mean corrosion rate at 96 h was 220Mpa, elongation >20%.
