5083 Aluminum Plate

Alloy 5083 aluminum plates have higher strength than 5052 plate and has exceptional thermal conductivity. In the tempered condition, it retains good formability due to excellent ductility. It is highly suitable for welding and can be hardened by cold work. Because Alloy 5083 exhibits excellent resistance to general corrosion, it is used in marine applications. Since Alloy 5083 is capable of withstanding extremely low temperatures without brittleness or loss of properties, it is especially suited to the cryogenic market. Alloy 5083 has been used in vehicle armor plate due to its high strength factor.
