5083 aluminum sheet is an aluminum alloy sheet that cannot be heat-treated to increase its strength. It is available in a variety of specifications and standards. Get the latest 5052 aluminum sheet prices now.
5083 aluminum plate is a high-performance aluminum–magnesium alloy, with magnesium as the primary alloying element and small additions of manganese and chromium. It belongs to the 5000 series aluminum alloys and is recognized as one of the strongest non-heat-treatable aluminum materials available.
This alloy combines low weight with high strength and outstanding resistance to seawater corrosion. Because of these properties, 5083 aluminum plate is widely used in marine engineering, shipbuilding, offshore structures, and aerospace-related applications. Its mechanical strength is achieved through cold working rather than heat treatment, which ensures stable performance in demanding environments.
As a professional aluminum plate supplier in China, Zggdmetal manufactures 5083 aluminum plates in a wide range of standard thicknesses and sizes to meet different project requirements. We can also support customized specifications to match your specific needs. The market price of 5083 aluminum plate varies depending on thickness, size, and order quantity.
