Aluminum 1100 sheet is a commercially pure aluminum. 1100 has excellent welding characteristics; it is also soft and ductile so is ideal for applications that require intricate forming as it work hardens slower than other alloys. 1100 is however non-heat treatable. As 1100 has excellent resistance to corrosion it is widely used in the chemical and food processing industries also for giftware and applications where eye appeal is important.
the 5052 aluminum alloy is used to make beverage closure without internal pressure. The raw material is 5052 H19 aluminum sheet, the material is first oxidized to improve the coating adhesion and corrosion resistance. After the two sides are painted, the can lid is formed. So 5052 aluminum is another material for processing closures. 5052 aluminum sheet has good oxidation coloring effect, excellent metal texture and hardness, wear resistance and corrosion resistance, long service life, and is widely used in high-end mobile phone casings, high-end air-conditioning casings and other fields with high requirements for oxidation and metal texture.
"the composition of 1100 or 1060 aluminum sheet pure aluminum Aluminum content greater than 99% is called pure aluminum, 1100 aluminum content is 99%, and 1060 aluminum content is 99.6%. Other ingredients are iron and silicon."
