Abstract

This invention provides a method for manufacturing high surface are aluminum strips. The aluminum strips are composed of (by weight parts) Al 100, Si less than 0.3, Fe 0.5-0.7, Cu 0.08-0.15, Zn 0.09-0.11 and Ti 0.01-0.05. The aluminum strips are manufactured by preparing the raw materials and mixing, smelting and casting into alloy ingots, homogenizing, hot-rolling, and cold-rolling to the thickness of the final products, shearing and annealing to form the final products. The aluminum strips in this invention are smooth and homogeneous in thickness, have high surface brightness, and can directly satisfy the requirements of high surface areas without any need for polishing.

Description

technical field [0001] The invention relates to an aluminum strip and a production method thereof. Background technique [0002] After the existing ordinary aluminum strip is rolled, its surface is an ordinary rolling surface. If the composition and structure uniformity of the ingot are not controlled, and the above-mentioned production process is not adopted, the fiber structure of the aluminum alloy ingot will be uneven and the grains will be uneven. Coarse particles, segregation and other abnormal structures, in the subsequent use process, will cause problems such as poor surface finish, insufficient brightness, black streaks, bright spots, plate shape quality, and unqualified difference between the same plate. Products that require a high surface generally need to be polished, which increases the production cycle and cost, and reduces the yield. Contents of the invention [0003] In order to solve the problems of long production cycle, high cost and low yield in the e...
