Description
Aluminium 5083 Plates
Aluminum 5083 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 Aluminium 5083 exhibits excellent resistance to general corrosion, it is used in Marine Applications. Since Aluminum 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.
Aluminium 5083 is known for exceptional performance in extreme environments. 5083 is highly resistant to attack by both seawater and industrial chemical environments. 5083 also retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys but is not recommended for use in temperatures in excess of 65°C.
5083 Aluminium plate is known for its excellent strength, weldability, and corrosion resistance, making it a popular choice in marine applications, transportation, and construction projects. Textron Steel and Alloys offers 5083 Aluminium plate in H111, H112, H116 and H321 temper etc.

Marine Applications :
5083 cast aluminum plate is used in a variety of marine applications, such as boat hulls, propellers, and rudders. It is resistant to corrosion in salt water, making it a good choice for marine applications. For example, it is used in the construction of boat hulls because it is strong and lightweight, making it a good choice for boats that need to be maneuverable and fuel-efficient. It is also used in the construction of propellers and rudders because it is resistant to corrosion and can withstand the harsh environment of the ocean.
