The invention discloses a high-toughness aluminum sheet strip for a new energy automobile and a production method of the high-toughness aluminum sheet strip. The high-toughness aluminum sheet strip for the new energy automobile comprises, by weight percentage, 0.01-0.08% of Si, 0.06-0.12% of Fe, 0.001-0.02% of Cu, 0.45-0.5% of Mn, 4.1-4.3% of Mg, 0.005-0.02% of Cr, 0.002-0.005% of La, 0.002-0.005%of Ce, 0.01-0.018 % of Ti and the balance Al. The production method of the high-toughness aluminum sheet strip comprises the steps of smelting, casting, milling, soaking, heating, hot rough rolling,hot finish rolling, cold rolling, annealing, finishing and the like. The prepared aluminum sheet strip has excellent properties such as high strength, high toughness, high elongation and high indentation resistance, is smooth in surface, free of orange peels and free of cracking when the stamping depth is 300 mm and can be widely applied to inner plates and outer plates of automobiles.
Description
technical field [0001] The invention belongs to the technical field of aluminum alloy processing, and in particular relates to a high-toughness aluminum strip for new energy vehicles and a production method thereof. Background technique [0002] New energy vehicles include pure electric vehicles, hybrid vehicles, fuel cell electric vehicles, and other forms of vehicles. While the automobile industry is booming, due to the needs of environmental protection and energy conservation, the weight of vehicles is reduced to reduce energy consumption and reduce environmental pollution. Savings are limited. Resources have become the focus of new energy vehicles. Lightweight is an important trend in the development of automobiles. By using lightweight materials to replace traditional steel materials, the weight of automobiles can be reduced to achieve the purpose of reducing energy consumption and saving fuel. [0003] Among many automotive lightweight materials, aluminum alloy has th...
