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 application of 5052 aluminium sheet are various auto parts, sheet metal parts, mechanical parts, automobiles, aircraft fuel tanks, warships, submarines, containers, household appliance use, refrigerator liners and so on. Performance of 5052 aluminum sheet: Tensile strength (σb): 170~305MPa, Yield strength (σb): 0.2 (MPa), Elastic modulus (E): 69.3~70.7Gpa, Annealing temperature: 345°C.
Aluminum 1100 sheet is among the softest aluminum alloys and therefore is not used for high-strength or high-pressure applications. Though it is often cold-worked, pure aluminum can be hot-worked as well, but more frequently, aluminum is shaped by spinning, stamping and drawing processes, none of which require the use of high heat. These processes prodsuce aluminum shapes in the form of foil,sheets, round barss or rodss, sheets, strips, and wires. Aluminum 1100 can also be welded; resistance welding is possible, but it can be difficult and usually requires the attention of skilled welders. Aluminum 1100 is just one of several common aluminum alloys and is soft, low strength and, at 99% min aluminum, is the commercially pure aluminum. Copper, iron, magnesium, manganese, silicon, titanium, vanadium and zinc comprise the remaining elements. It cannot be hardened by heat treatment and is very formable.
