The invention provides an aluminum alloy non-texture standard sample and a preparation method thereof. The preparation method comprises the following steps that primary aluminum powder or mark aluminum powder is placed in a forming mold, then the forming mold is placed in a plasma forming testing machine, powder metallurgy plasma sintering is carried out on the primary aluminum powder or the mark aluminum powder, and an aluminum alloy non-texture standard sample is obtained, wherein the forming temperature in the powder metallurgy plasma sintering process of the primary aluminum powder is 500-520 DEG C, and the forming temperature in the powder metallurgy plasma sintering process of the grade aluminum powder is 520-550 DEG C. By adopting the preparation method provided by the invention, the qualified aluminum alloy non-texture standard sample can be prepared. The standard sample fully keeps the disordered and uniform state of the aluminum powder, and can be applied to defocusing correction of an aluminum allo
