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 plate, in the 1000 series pure aluminum alloys, 1050 aluminum has higher strength, it is almost the same as 1060 aluminum.
“Anodized Aluminum sheet products and components are used in thousands of commercial, industrial and consumer applications, including: Structures and architectural categories of all types Appliances Commercial and residential building products Food preparation equipment Furniture Sporting goods and boats Motor vehicle components”
“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.”
