The 1050 aluminum alloy is formed from pure aluminum by added a small amount of copper element, and the 1050 aluminum plate has low strength, excellent formability, surface treatment property, weldability and corrosion resistance. Besides, the industrial pure aluminum has the characteristics of high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but the strength is low, it can not be strengthened by heat treatment, the machinability is not good, and contact welding and gas welding are acceptable. The higher the purity, the lower the hardness of the aluminum plate, in the 1000 series pure aluminum alloys, 1050 aluminum has higher strength, it is almost the same as 1060 aluminum.

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.

1, Aluminum alloy with Mg as the main alloying element. The magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. 2, can not be heat-treated. 3, the density is small (2.68). The weight of aluminum-magnesium alloy is lower than other alloys in the same area. 4, has higher strength than 1000, 3000 series aluminum, is a medium high strength aluminum alloy, has good fatigue resistance and welding performance. 5052 has high tensile strength and high elongation. 5, resistance to marine atmospheric corrosion is better. 6, 5052 aluminum sheet is a hot-rolled aluminum plate series, so it can do oxidation deep processing.
