| description | The invention relates to the technical field of mobile phone shells, in particular to a rear earth cast aluminum alloy mobile phone shell and a preparation method thereof. The rear earth cast aluminumalloy mobile phone shell is prepared from raw materials of Si, Fe, Mg, Mn, Sc, Ti and Al, and obtained through heating and melting, refining and degassing, refining and modifying, die casting, machining and surface treatment. According to the rear earth cast aluminum alloy mobile phone shell, the aluminum alloy containing Sc is taken as a raw material, anodizing is conducted after machining, thestructure of the mobile phone shell is compact, the surface performance is excellent, material lines, black spots and black line defects are avoided, and good stamping and forming performance, cuttingmachining and corrosion resistance are achieved; and in addition, the preparation of the rear earth cast aluminum alloy mobile phone shell is less in process, low in cost and high in yield, the preparation method is suitable f |
