Aluminium alloy foil material for container and method for producing the same

Abstract

The invention discloses an aluminum alloy foil used for containers, which is characterized in that: the components and the weight ratios are: 0.42 to 0.52 percent of iron, 0.05 to 0.20 percent of silicon, 0.04 to 0.13 percent of copper, 1.10 to 1.30 percent of manganese, 0.020-0.040 percent of titanium and the residual quantity of aluminum. The manufacturing method of the aluminum alloy foil used for containers comprises slab casting and rolling, pre-annealing, plank cold rolling, intermediate annealing, cold rolling, finished product annealing, greasing and cutting. Compared with the prior art, the aluminum alloy foil has the remarkable advantages: higher tensile strength and elongation; good deep-drawing performance, formability and stiff and smooth degree, beautiful appearance, uniform color and luster without defect, thus meeting the requirement of the users.

Description

technical field

[0001] The invention relates to an aluminum alloy foil material for containers, and also provides a manufacturing method of the aluminum alloy foil material. Background technique

[0002] Because aluminum foil has the advantages of easy forming, beautiful appearance, easy disinfection, low cost, and convenient recycling, aluminum foil containers of deep-processed products are widely used, and can be made into containers for fruits and other foods, plates, lunch boxes, and lunch boxes on airplanes , refrigerator boxes, cold storage containers, etc. Aluminum foil for containers is required to have high tensile strength and elongation, good deep drawability, formability, and stiffness, and the appearance and color are uniform and beautiful without defects. At present, this kind of aluminum foil is often produced by hot rolling technology, and the cost is relatively high. However, when casting and rolling technology is used for production, there are generally d...
