[0029] according to figure 1 As shown, the embodiment of the present invention also provides a preparation method for preparing the above-mentioned aluminum veneer material with high tensile strength, and the specific steps are as follows:
[0030] S1. Add pure aluminum into the smelting furnace for melting, and sequentially add copper, silicon, magnesium, zinc, titanium, iron and rare earth elements to the smelting furnace. Under the conditions, the aluminum alloy liquid is prepared by stirring;
[0031] S2, adding a refining agent to the aluminum alloy liquid, and continuously stirring and refining, and then adding a slag cleaning agent for slag removal;
[0032] S3. Prepare upper and lower plate-shaped molds. The upper plate-shaped mold is a concave structure with a wall thickness of 2 cm and a depth of 3 cm. Part of the aluminum alloy liquid is added to the lower plate-shaped mold to form a lower aluminum-based alloy layer, and a pressing template is used. The surface la...
Embodiment 1
[0038] Embodiment 1 An aluminum veneer material with high tensile strength and a preparation method thereof, comprising:
[0039] 1. Add pure aluminum into the smelting furnace for melting, and sequentially add copper 1%, silicon 1%, magnesium 0.5%, zinc 0.5%, titanium 0.2-%, iron 0.3% and rare earth elements 0.1% to the smelting furnace. Under the condition of 750 ℃ and stirring rate of 80 r / min, the aluminum alloy liquid was prepared by stirring;
