Abstract

The invention relates to the technical field of aluminum alloy templates, and discloses a lightweight aluminum alloy template and a preparation method thereof.The template is prepared from, by weight, 0.5%-1.5% of nano zinc oxide, 1.5%-1.9% of nano titanium dioxide, 0.6%-1.3% of nano Ni, 0.2%-0.5% of nano silicon carbide, 2.5%-6.5% of zinc, 1.2%-2.6% of copper, 0.8%-1.6% of magnesium, 0.2%-0.8% of zirconium and the balance aluminum. Then adding nano silicon carbide, nano zinc oxide, nano titanium dioxide and nano Ni, stirring at a high speed for 10-20 minutes, and standing; sequentially adding zinc, copper, magnesium and zirconium into the first mixed solution, stirring for 1-2 hours, cooling to 650-680 DEG C, and standing for 15-25 minutes to obtain a second mixed solution; the second mixed solution is poured and rolled into an aluminum alloy plate with the thickness of 2.5-3.0 mm, and then annealing is conducted; and the aluminum alloy plate is cut, punched and welded, and the aluminum alloy formwork is prepared. The strength and the service life of the aluminum alloy formwork can be guaranteed under the conditions that the thickness of the aluminum alloy formwork is reduced, the weight of the aluminum alloy formwork is reduced, and construction is facilitated.
