The 1050 aluminum alloy is formed from pure aluminum by added a small amount of copper element, and the 1050 aluminum sheet 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 sheet, 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.
Aluminum 2014 is a precipitation hardening alloy with fair corrosion resistance, high electrical conductivity, and good machinability. As one of the strongest aluminum alloys on the commercial market, 2014 Aluminum is heavily used in the manufacture of aircraft and truck parts, as well as in forging applications. 2014 alloy is primarily aluminum based, with copper being the other major element. Standard specifications for 2014 include ASTM B209, UNS A92014 and more.
