what is 1100 aluminum sheet?

2019-01-29

Aluminum 1100 sheet is a commercially pure aluminum. 1100 has excellent welding characteristics; it is also soft and ductile so is ideal for applications that require intricate forming as it work hardens slower than other alloys. 1100 is however non-heat treatable. As 1100 has excellent resistance to corrosion it is widely used in the chemical and food processing industries also for giftware and applications where eye appeal is important.

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.

"Heat treatment cannot be used to make it hardenable. Compared to 5005 alloys,5052 aluminum has better resistance in marine environments. It also has excellent corrosion resistance when used in slightly alkaline conditions. A protective surface film is over the 5052 aluminum, which gives the metal its corrosion resistance. When damage happens, the rapid reaction between aluminum and oxygen repairs it. When the film can’t be repaired, corrosion can quickly occur to the base metal. To help prevent this from happening, the metal can be anodized, which will make the protective surface film thicker. Heat treatment can be used on this metal, which should be performed at 653 degrees F; the cooling rate and time at this temperature isn’t important. It’s rare for stress relief to be needed, but can be done at 428 degrees F. Stress relief should be used when the loss of strength is a concern. This metal is also readily machinable and weldable. 5052 aluminum sheets can be purchased in sizes between .032 and .1875 inch thick, 48 and 60 inches wide and up to 144 inches thick."
