Problems solved by technology

[0002] At present, the aluminum foil used to produce medicine foil in the market generally adopts 1145 alloy. The surface quality of the aluminum foil produced by 1145 alloy is good, but due to its low alloy content and soft strength, it leads to poor rolling performance, resulting in low production efficiency and yield, etc. problems, and sometimes the strength is soft, and it cannot meet the requirements, and the rupture strength is relatively low

Abstract

The invention discloses an aluminum foil and a production method thereof. The aluminum foil comprises the following components in percentage by weight: 0.57-0.63 percent of Si, 0.77-0.83 percent of Fe, not more than 0.05 percent of Cu, not more than 0.05 percent of Mn, not more than 0.05 percent of Mg, not more than 0.05 percent of Cr, not more than 0.05 percent of Zn, not more than 0.05 percent of Ti and the balance of Al. The method comprises the concrete steps of smelting, casting, cold rolling, intermediate annealing and foil rolling. The invention has the advantages that the aluminum foil for producing explosion foil can be produced according to the improvement on the production method and the accuracy of process parameters and has the advantages of high surface quality, high strength, favorable cracking strength and high stability for cold rolling as well as improved production efficiency and finished product rate.

Description

technical field [0001] The invention relates to an aluminum foil and a manufacturing method thereof, in particular to an aluminum foil for producing medicine foil and a manufacturing method thereof. Background technique [0002] At present, the aluminum foil used to produce medicine foil in the market generally adopts 1145 alloy. The surface quality of the aluminum foil produced by 1145 alloy is good, but due to its low alloy content and soft strength, it leads to poor rolling performance, resulting in low production efficiency and yield, etc. Problems, and sometimes the strength is soft, can not meet the requirements, and the rupture strength is relatively low. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to address the deficiencies of the prior art and provide an aluminum foil for producing medicine foil with high strength, good burst strength and high rolling stability and its manufacturing method. [0004] Technical solu...
