High-end anodic oxidation aluminum strip for 3C (computer, communication and consumer electronic) industry and production method of high-end anodic oxidation aluminum strip

Abstract

The invention discloses a high-end anodic oxidation aluminum strip for the 3C (computer, communication and consumer electronic) industry and a production method of the high-end anodic oxidation aluminum strip. Chemical alloy elements of the aluminum strip comprise Si, Fe, 0.04-0.08% of Cu, Mn, 2.3-2.5% of Mg, Cr, Zn, 0.008-0.012% of Ti and the balance Al, wherein the percent of Si is smaller than or equal to 0.03%, the percent of Fe is smaller than or equal to 0.05%, the percent of Mn is smaller than or equal to 0.01%, the percent of Cr is smaller than or equal to 0.01%, and the percent of Zn is small than or equal to 0.01%. The production method includes: smelting the aluminum alloy elements to obtain aluminum alloy ingots by casting; subjecting the aluminum ingots to end sawing and surface milling; performing soaking and heating treatment; sequentially carrying out cold rough rolling and hot finish rolling; subjecting aluminum alloy coils to intermediate annealing or stabilization treatment, and finally cleaning, dividing and packaging. By the aluminum strip produced according to the production method, quality problems of high internal hydrogen content, texture nonuniformity, surface black lines, streaks and the like in production of aluminum alloy strips for electronic appliances in the prior art can be solved effectively.
