Aluminum lid sheet material

The history of the development of Aluminum lid sheet material
There are two kinds of materials for making cans: one is aluminum and the other is tinplate.
In 1940, stainless steel canned beer was sold in Europe and America. The appearance of aluminum cans in the same period also became a leap in can manufacturing technology. In 1963, cans were invented in the United States. It inherits the characteristics of the previous can-shaped design and has a pull-tab at the top.
This is a revolution in the way of opening up, bringing great convenience and enjoyment to people, and it is quickly becoming universally applied. By 1980, the European and American markets basically used this aluminum can as a packaging form for beer and carbonated beverages. With the advancement of design and production technology, aluminum cans have become lighter, from the initial 60 grams to 21 to 15 grams in 1970.
 
Introduction of Aluminum lid sheet material
As far as the composition of the can itself is concerned, it is mainly composed of three kinds of aluminum alloys. The can body and the bottom of the can are 3004 aluminum alloy, the can lid is 5182 aluminum alloy, and the pull ring is 5042 aluminum alloy.
 
Advantages of Aluminum lid sheet material
1, aluminum production costs are lower
2, Aluminum lid sheet material can be used as recyclable materials, greatly improving the recycling rate
3, Aluminum lid sheet material can greatly reduce the waste of materials, more environmentally friendly;
4. From the material itself, the Aluminum lid sheet material have good ductility and are more suitable for the manufacture of cans.
