Abstract: A corrosion resistant Zn—Mg alloy implant material of high strength and toughness and absorbable by the human body, the alloy implant material having: 96 wt % to 99.98% Zn and 0.002 wt % to 4% Mg. The alloy implant material is applied to absorbable medical implants, particularly vascular stents and orthopedic implants. The alloy implant material can be absorbed in the human body environment, avoiding pain to patients caused by secondary surgery, and has much better corrosion resistance than magnesium alloy, and being able to achieve the two indexes of high corrosion resistance and high strength and toughness.

Abstract: A kind of absorbable high strength & toughness corrosion-resistant zinc alloy implant material for human body, the elemental constituent and quality percent: Ce0.001%-2%, Mg0.001%-2%, Ca0.001%-2%, Cu0.01%-3%, others are Zn. Above-mentioned zinc alloy material is prepared as absorbable medical implant by using conventional method in this field, especially for intravascular stent, orthopedic implants (bone nail or plate etc.). Zinc alloy material created by this invention has high corrosion-resistant and high strength & toughness, the medical implant prepared by this can be absorbed by the body without side effects.
