3004 aluminum sheet is a non- heat treatable aluminum alloy with manganese as its primary alloying element. It is similar to 3003 except for the addition of approximately 1% magnesium. It can be used to prodsuce tempers with a higher strength but a lower ductility.
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.
5052-H32 Aluminum Sheet Superior corrosion resistance, good weldability, with excellent formability, makes 5052 Aluminum Sheet a common choice for chemical, marine or saltwater applications. 5052 Aluminum Sheet applications include: tanks, marine hardware, boat hulls, etc.
