Problems solved by technology

[0003] The existing high-strength aluminum alloy plates have certain disadvantages during processing. First, the content of each added element cannot be determined during the processing, and it is impossible to accurately produce aluminum alloy plates with high strength and formability. Secondly, the traditional water quenching The temperature is mostly room temperature, and it is easy to affect the processing quality of the aluminum alloy plate due to the low water temperature. Finally, the traditional processing cannot integrate the raw materials well, and cannot make the materials fully mix and play their respective characteristics. Therefore, we propose a high strength aluminum alloy plate

Abstract

The invention discloses a high-strength aluminum alloy plate. The high-strength aluminum alloy plate is prepared from, by weight, 5.8%-8.2% of silicon, 2.6%-5.4% of copper, 2.8%-6.3% of magnesium, 7.8%-10.7% of zinc, 0.1%-0.5% of chromium, 0.1%-0.4% of titanium, aluminum and unavoidable impurities. According to the high-strength aluminum alloy plate, the strength and the good molding property of the aluminum alloy plate can be improved by adding zinc, iron and titanium metal additives; it can be guaranteed that the contents of the components are accurate through spectrum analysis of a spectrumanalyzer; the water temperature is controlled at 20 DEG C or above in the water quenching process, and therefore the condition that the aluminum alloy plate machining quality is influenced due to thefact that the water temperature is too low can be avoided; and a hot rolling method is adopted as a machining method, through a series of machining including smelting, refining, annealing, casting, hot rolling, water quenching, cold rolling, finishing and artificial aging treatment, fusion machining can be well conducted on raw materials, the materials are fully mixed, a finished product meets any needed roughness machining after being subjected to finishing, and a better using prospect is brought.
