The invention provides a ZA4 alloy and a preparation method and application thereof, and relates to the technical field of pure zirconium materials. The ZA4 alloy provided by the invention comprises the following components in percentage by mass: 0.2 to 0.6 percent of Fe, 0.1 to 0.3 percent of O, 0.5 to 4 percent of Hf and the balance of Zr. According to the method, trace Fe and O elements are added, so that the grain size of the ZA4 alloy is obviously refined in the smelting and cooling process, the growth of alpha grains in the thermal deformation and treatment process is inhibited, Hf belongs to a neutral element, the solution strengthening effect in the alpha phase is obvious, and the strength and plasticity of the ZA4 alloy obtained by strictly controlling the content of all the elements are high. The method is simple to operate, low in production cost and suitable for industrial production. 本发明提供了一种ZA4合金及其制备方法和应用，涉及纯锆材料技术领域。以质量分数计，本发明提供的ZA4合金包括：Fe0.2～0.6％，O0.1～0.3％，Hf0.5～4％和余量的Zr。本发明添加微量的Fe和O元素，使得ZA4合金的
