Aluminium Can Sheet

0 Comment

Aluminium can sheet 3004, 3104, 5082, 3003 are used for making can body, can lip, can pull ring, the whole can is able be all aluminum. The advantages of aluminum cans are that they are not easily broken, light in weight, and opaque to light. Common carbonated beverages on the market (cola, beer, etc.) use aluminum cans because aluminum cans are not easily corroded by acid, and aluminum cans are easy to form and relatively inexpensive to manufacture. The pressure in the soda is higher than the normal pressure, under the action of the pressure, there is no need to worry about deformation. Moreover, the aluminum can can ensure the pressure of carbon dioxide in the soda, so that the soda can achieve a better taste effect. Therefore, a strong and durable aluminum can is required to prevent deformation during transportation and storage. Aluminum cans are not made of pure aluminum, but aluminum alloy.

The can-type Coca-Cola is packaged in aluminum alloy, and the aluminum alloy can pull ring, aluminum alloy can lid and can body are all made of different alloy aluminium can sheet. 5182 aluminum sheet is mostly used for the pull ring of the can, and 3004 aluminum sheet is used for the lid of the can. Aluminum alloy sheets used for cans are generally made of 3004 and 3104 alloys containing Mn and Mg. The main alloy elements of 3000 series aluminum sheet for can making are Mn and Mg, while Fe and Si are the main impurity elements. The solid solution strengthening effect of Mn and Mg elements is used. Improve the strength of the material, but the diffusion rate of Mn in Al is very slow, and it is easy to form coarse compounds, and Fe has a certain improvement in this.


The can is formed by one-time stamping with aluminium can sheet. The can aluminum sheet is plastically deformed to obtain the shape of the can cover, resulting in optimistic deformation and strengthening, so that the stamping parts have the characteristics of light weight, high strength and good rigidity. It has the characteristics of good strength, corrosion resistance, good machinability, high surface finish, and is very suitable for post-processing. Aluminum cans have the advantages of light weight, heat resistance, good conductivity, odorless and non-toxic and good printing effect.
