Provided are a biodegradable zinc-copper alloy material which can be used in a medical implant material, and a preparation method and use thereof. The material is mainly composed of the following substances: 1-10 wt.% of copper, and the rest is zinc and other impurity elements. An as-cast alloy ingot is subjected to a homogenization heat treatment, then can be subjected to a thermoplastic deformation processing so as to refine the alloy structure, thereby improving the mechanical properties of the alloy, and at the same time, the alloy can be further prepared into a pipe, a wire, a sheet and the like. The zinc alloy has advantages such as good mechanical properties, easy processing, a good corrosion resistance, and a good biocompatibilty, and can be used as a material for preparing various degradable medical implant instruments. The zinc alloy not only has very good mechanical properties and biocompatibilty, but also the complete degradation thereof can be achieved within 6-18 months, meeting the requirements of an implant instrument for the comprehensive mechanical properties and biosecurity of a material. |
