A kind of 3004 aluminum foil and its preparation method and application

Abstract

The invention discloses a 3004 aluminum foil, a preparation method and application thereof. The aluminum foil contains the following chemical elements in mass percentage: Si 0.15-0.25%, Fe≤0.55%, Cu 0.14-0.2%, Mn 1.02-1.15%, Mg 0.95-1.1%, Cr≤0.05%, Zn≤0.15 %, Ti 0.015~0.025%, other <0.1%, and the rest is Al. Through smelting, refining, standing still, on-line degassing and slag removal, casting, milling, soaking treatment, hot rolling, cold rolling, intermediate annealing, cold foil rolling and finished product annealing, 3004 is obtained after the finished product annealing Aluminum foil; through the combination of various elements and the preparation process, the aluminum foil prepared has high strength and good toughness. When used as a container, the thinness is greatly reduced, it is convenient to use, and the amount of raw materials is reduced; Using discarded cans as raw materials reduces raw material consumption, realizes resource reuse, broadens the source of raw materials for preparing aluminum foil, avoids the burden on the environment, reduces production costs, and has good social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy materials, and in particular relates to a 3004 aluminum foil and a preparation method and application thereof. Background technique [0002] Aluminum foil has the characteristics of light material, high barrier property, shading, anti-ultraviolet, moisture-proof, corrosion-resistant, heat-resistant, clean and hygienic; in deep processing and utilization, it has the characteristics of easy bending, excellent forming performance, excellent surface printing performance and decorative effect, so , aluminum foil is widely used in various fields, and has a wide range of uses in the food industry, household life, aviation and other industries. Among them, many aluminum foil aluminum containers are used as disposable products and have a great demand. [0003] Under the condition of a large demand for aluminum foil materials, its preparation process has also been well developed. At present, 8011 se...

AI Technical Summary

Problems solved by technology

At present, 8011 series and 3003 series aluminum alloys are mostly used for the preparation of aluminum foil. The aluminum foil prepared by this material has low strength and needs a large thickness when used as a container, otherwise it cannot be used without support

Not only brings inconvenience to the use process, but also causes waste of raw material resources
