Problems solved by technology

[0003] In order to prevent the decrease in the strength and hardness of the can body caused by this thermal softening, and the deformation, if the wall thickness is increased, the weight of the can will increase. In addition, when the strength of the aluminum material itself is increased without increasing the wall thickness, the above reduction In thin deep drawing, there is a failure phenomenon of fracture
Therefore, in view of this problem, only existing tank materials and methods can no longer cope with the production of tank rims through necking and flange processing.

Abstract

The invention relates to an aluminum alloy plate for a high temperature resistant packaging tin. The aluminum alloy plate is composed of the following materials by weight percent: 1.0-1.2% of Mn, 1.0-1.2% of Mg, 0.3-0.5% of Fe, 0.1-0.3% of Si, 0.3-0.5% of Cu and 0.5-0.8% of Zn, and the balance of Al and inevitable impurities. Through the technical scheme of the aluminum alloy plate for the high temperature resistant packaging tin, the strength of the alumium alloy plate is improved while a thin wall is realized.

Description

technical field [0001] The invention belongs to the field of metal materials, and refers to a rolled plate rolled through hot rolling-cold rolling, in particular to an aluminum alloy plate for high-temperature-resistant packaging cans. Background technique [0002] As beverage cans, two-piece aluminum alloy cans obtained by seaming the can body and the can lid are often used. The tank body is made of aluminum-based cold-rolled plates that are deep-drawn, thinned and deep-drawn, trimmed to a specified size, degreased, cleaned, painted and printed, and baked with colored flowers. [0003] In order to prevent the decrease in the strength and hardness of the can body due to this thermal softening, and the deformation, if the wall thickness is increased, the weight of the can will increase. In addition, when the strength of the aluminum material itself is increased without increasing the wall thickness, the decrease in the In thin deep drawing, there is a failure phenomenon of f...
