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.
3003 Aluminum Alloy contains Manganese as its major alloying element. 3003 Aluminum is an alloy with very good corrosion resistance and moderate strength. It is not heat treatable and develops strengthening from cold working only. 3003 Aluminum Alloy has good machinability and welding is readily accomplished by means of conventional welding methods. Commonly used in chemical equipment, ductwork, and in general sheet metal work. 3003 Aluminum is typically used in stampings and the manufacturing of pressure vessels, builder’s hardware, garage doors, awning slats, refrigerator panels, gas lines, gasoline tanks, heat exchangers, drawn and spun parts, and storage tanks. All of our 3003 Aluminum Sheet is protected on one side with a protective vinyl film.
