A production method for baseball bats based on 6-series recycled aluminum is provided, which includes steps such as pretreatment, melting, casting, homogenization treatment, extrusion, drawing, and subsequent processing. In the casting step, the crystallizer adopts electromagnetic stirring treatment to disperse larger Fe containing phases. In the homogenization treatment step, it is divided into primary and secondary homogenization two stages. The purpose of the primary homogenization treatment is to dissolve the Mg2Si phase with a low melting point into the matrix, and the purpose of the secondary homogenization treatment is to transform the elongated β-AlFeSi into spherical α-Al(FeMn)Si to eliminate harmful Fe phases. Heating treatment is used on the drawing mold during the drawing process, and warm forming helps to make aluminum alloy drawing smoother, reduce cracking, and eliminate the need to add other alloys during the production process of recycled aluminum melting.
