Embodiment Construction
[0018] Below in conjunction with embodiment the method of the present invention is further described.
[0019] An aluminum alloy automobile wheel hub and a preparation method thereof. The technical proposal lies in that the wheel hub is composed of aluminum ingots, silicon elements, magnesium elements, titanium elements, and strontium elements.
[0020] The specific implementation is as follows:
[0021] 1. Selection of aluminum ingots: select aluminum ingots for remelting with an aluminum content of ≤99.80% as raw materials for production.
[0022] 2. Raw material composition and ratio: aluminum ingot 98.835%, silicon element 0.7%, magnesium element 0.3%, titanium element 0.15%, strontium element 0.015%.
[0023] 3. Smelting: Add aluminum ingots into the melting furnace to melt to obtain aluminum solution, and then add the above-mentioned silicon, magnesium, titanium and strontium elements to the aluminum solution to obtain a mixed aluminum solution.
[0024] 4. Casting: Pr...
