3004 aluminum foil and preparing method and application thereof

Abstract

The invention discloses 3004 aluminum foil and a preparing method and application thereof. The aluminum foil comprises chemical elements: by mass, 0.15-0.25% of Si, smaller than or equal to 0.55% of Fe, 0.14-0.2% of Cu, 1.02-1.15% of Mn, 0.95-1.1% of Mg, smaller than or equal to 0.05% of Cr, smaller than or equal to 0.15% of Zn, 0.015-0.025% of Ti, smaller than 0.1% of other chemical elements andthe balance Al. The 3004 aluminum foil is obtained by performing 3004 aluminum alloy smelting, refining, standing, online degassing and deslagging, casting, face-milling, uniform heating treatment, hot rolling, cold rolling, intermediate annealing, cold foil rolling and finished product annealing. With the combination of the various elements and the preparing process, the prepared aluminum foil has high strength and toughness, the thickness is greatly reduced when the aluminum foil is used as a container, use is convenient, and the consumption of the raw materials is reduced; and waste ring-pull cans can be adopted as a raw material, the consumption of the raw material is reduced, resources are reutilized, the source of the raw materials for preparing the aluminum foil is widened, meanwhile the burdens on the environment are avoided, the production cost is reduced, and the 3004 aluminum foil has quite good social 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
