The invention relates to a biomedical absorbable Mg-Si-Sr-Ca multi-element
magnesium alloy material as well as a production method and application thereof. The biomedical absorbable Mg-Si-Sr-Ca multi-element
magnesium alloy material is suitable for being used as an
implant material used in a
human body environment. The biomedical absorbable Mg-Si-Sr-Ca multi-element
magnesium alloy material comprises the following components in percentage by weight: 0.1%-20.0% of Si, 0.1%-8.0% of Sr, 0.1%-10.0% of Ca and the balance of Mg. The biomedical absorbable Mg-Si-Sr-Ca multi-element
magnesium alloy material is a multi-element
magnesium alloy system consisting of total
nutrient elements of Mg, Si, Sr and Ca; the form, quantity and distribution of a plurality of second phases such as Mg2Si, Mg2Sr, Mg17Sr2, Mg2Ca, CaMgSi and the like in the
magnesium alloy are controlled, so that the multi-element magnesium alloy with the optical comprehensive performances is obtained. The biomedical absorbable Mg-Si-Sr-Ca multi-element magnesium alloy material disclosed by the invention has good
biocompatibility and mechanical properties, and is a
biodegradable magnesium alloy material with excellent comprehensive performances. Besides, the biomedical absorbable Mg-Si-Sr-Ca multi-element magnesium alloy material has a high application value in the fields such as
interventional therapy for cardiovascular diseases, intraosseous
implant and the like.
