Problems solved by technology

However, the strength of tinplate is high, the yield strength is generally 510MPa ~ 560MPa, the elongation is low, generally not more than 2%, and the formability is not good in the process of can making
In addition, in the packaging industry, tinplate has a high density, and it needs to be transported multiple times in various links such as can making, filling, and terminal sales, which greatly increases the transportation cost

Abstract

The invention discloses an aluminum alloy plate as well as a production method and applications thereof and belongs to the technical field of aluminum alloy plates. The aluminum alloy plate comprises the following components in percentage by weight: 0.15-0.25% of Si, 0.4-0.46% of Fe,0.16-0.18% of Cu, 0.84-0.92% of Mn, 1.17-1.23% of Mg, Cr less than or equal to 0.04%, 0.02-0.07% of Zn, Ti less than or equal to 0.02%, other single impurities less than or equal to 0.05%, other impurities less than or equal to 0.15% and the balance of Al. The aluminum alloy plate has an excellent forming performance. The production method of the aluminum alloy plate comprises the steps of smelting and casting, saw cutting and surface milling, uniformizing, hot continuous rolling, cold rolling, cleaning and annealing; and the production method is simple in process and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy plates, in particular to an aluminum alloy plate, a production method and an application thereof. Background technique [0002] At present, in the metal packaging industries such as beverages, medicines, cosmetics, and cigarettes, aluminum alloy plate, strip and foil products have been widely used, but tinplate (tin-plated thin steel plate) is still mostly used in food metal packaging, such as various meat, fish, etc. Class cans, milk powder cans and pet food cans, etc. However, the tinplate has high strength, the yield strength is generally 510MPa-560MPa, the elongation is low, generally not more than 2%, and the formability is not good in the can making process. In addition, in the packaging industry, tinplate has a high density, and it needs to be transported multiple times in various links such as can making, filling, and terminal sales, which greatly increases the transportation cost....
