Soluble magnesium alloy and preparation method thereof

The invention relates to a preparation method of a soluble magnesium alloy, which comprises the following steps: weighing the following raw materials in percentage by weight: 1.6-1.8% of Ni, 1.2-1.4% of Cu, 0.2-0.3% of Al, 0.1-0.2% of Si and the balance of Mg, sequentially feeding the Ni, the Cu, the Al, the Si and the Mg into a smelting furnace to be completely smelted to obtain a smelted material, and finally carrying out hot warm treatment to obtain the soluble magnesium alloy after the treatment is finished. According to the soluble magnesium alloy, Ni, Cu, Al, Si and Mg serve as base materials and are smelted through a smelting furnace, and raw materials in the base materials are matched with one another, so that the strength, the ductility performance and the degradability effect of a product base are enhanced. 本发明涉及一种可溶镁合金的制备方法，包括以下步骤：按照重量百分比称取原料：Ni 1.6～1.8％、Cu 1.2～1.4％、Al 0.2～0.3％、Si 0.1～0.2％、余量为Mg，将Ni、Cu、Al、Si、Mg依次送入到熔炼炉中熔炼完全，得到熔炼料，最后再热温性处理，处理结束，即可得到可溶镁合金。本发明可溶镁合金采用将Ni、Cu、Al、Si、Mg作为基体料，通过熔炼炉熔炼，以基体料中的
