Can the Aluminum Alloy of the Can Replace the Aluminum Alloy of the Aluminum Sheet?

As a Perforated Metal Sheets Factory, share with you.

As we all know, the curtain wall aluminum veneer is made of aluminum alloy. The Coca-Cola cans are also made of aluminum alloy. However, most people think that aluminum alloys are the same, and there is no difference. In fact, they are different. The aluminum alloy used in cans cannot meet the basic mechanical properties of curtain wall aluminum veneers.

3104 aluminum alloy is used for the can body, 5052 aluminum alloy is used for the lid and pull ring of the can; and the aluminum alloy used for the aluminum veneer of the curtain wall is 1100 and 3003 aluminum alloy. Because of the different models of aluminum alloys, their mechanical properties are also different. For example, the ultimate tensile strength of 6061 aluminum alloy is 124MPa, the tensile yield strength is 55.2MPa, the elastic modulus is 68.9GPa, and the bending ultimate strength is 228MPa. It is usually used in aviation and shipbuilding. The mechanical performance requirements of curtain wall aluminum veneer do not need to meet the aviation aluminum alloy standards, but the aluminum alloy used for cans obviously cannot meet its basic mechanical performance requirements. In order to make huge profits, some aluminum manufacturers use shoddy aluminum to reproduce the recycled aluminum scrap into aluminum coils and sell them to aluminum veneer manufacturers. The curtain wall aluminum veneer formed by using this low-grade aluminum alloy is not distinguishable from the surface of the aluminum veneer, but after a long time of use, problems of corrosion and structural strength reduction will occur. The aluminum alloy used in the curtain wall aluminum veneer should strictly comply with the relevant quality standards of the construction industry promulgated by my country.

Of course, the vigorous development of curtain wall aluminum veneer is inseparable from the continuous development and innovation of aluminum alloy smelting technology. It is also expected that aluminum alloys with better mechanical properties will be used on building curtain walls in the future.
