By lightweight aluminum sheets you may indicate that aluminium sheets are light or that you are searching for the lightest of aluminum sheets. Confusing as it is, it’s not difficult for experts to understand, since aluminium is the lightest of all common industrial metals. The density of aluminum is 2.7, which is a commonly used light metal material. Although the density of magnesium is smaller than that of aluminum, and the density of magnesium is 1.7, magnesium can not be made into metal materials alone. It must be made into alloy materials with other metal materials, such as aluminum magnesium alloy(5xxx aluminum alloy), with the smallest density of 2.15, which is smaller than that of aluminum.

 

Take 5052 aluminum sheet, the most commonly applied in 5xxx alloy sheets, for example. It has a density of 2.68. Under the same area, the weight of 5 series of aluminum magnesium alloy is lower than that of other series of aluminum alloy plates. However, the light aluminum magnesium alloy has higher strength than the 1,3 aluminum plate, which belongs to the medium high strength aluminum alloy. The 5 series aluminum magnesium alloy plate also has the characteristics of high tensile property and high elongation. It belongs to the hot rolling aluminum plate series, so it can do deep oxidation processing and has a certain corrosion resistance. It is a mature product in many series of aluminum alloy products in the industry.

 

The main element of 5 5xxx lightweight aluminum sheets is magnesium, which is generally called as aluminum magnesium alloy by the insiders. Generally, the magnesium content is between 3% and 5%. Our commonly used 5 series aluminum plate mainly includes 5052, 5083, 5005 and 5A05. 5 series aluminum plate is widely used in ship manufacturing, automobile and aircraft welding parts. It is also an important material for the manufacture of automobile and aircraft fuel tanks. The 5 series aluminum plate is also used for military products, such as the construction of some warships and submarines, which are all made of 5 series aluminum magnesium alloy. However, you are still advised to contact your supplier before choosing a suitable grade.
