5083 Aluminum Sheet

Characteristics

5083 aluminum sheet is a high strength material, exhibiting  higher strength than 5052 sheet.5083 H116 is an alloy used for high strength welded applications, with excellent marine environment corrosion resistance. It has a superior “skin finish” developed to prevent skin lamination, thus providing even better resistance to inter-granular corrosion than alloy 5083 H321. It has higher Tensile and Yield strengths than Alloy 5086 but less than 5456. Aluminium 5083 is a strong magnesium-manganese-chromium-aluminium alloy. It can be hardened by cold work, but is not heat treatable to higher strength. It has good ductility for the strength level, better than most other 5000 series alloys. Aluminium alloy 5083 contains 5.2% magnesium, 0.1% manganese and 0.1% chromium. In the tempered condition, it is strong, and retains good formability due to excellent ductility. It has the low density and excellent thermal conductivity common to all aluminium alloys. Alloy 5083 is best known as a plate for ship building.The alloy is also produced as extruded seamless tube and other extrusions and as forgings.

5083 Aluminum Alloy – Supplied in sheet marine grade tempers H116, H321, H323; to spec ASTM B928. Tempers.O, H112, H32; to spec ASTM B209, and extrusion shapes in various tempers and specifications. This is an excellent marine environment corrosion resistant aluminum alloy, It is primarily an alloy used for its corrosion resistant properties as it is especially good on inter granular corrosion resistance. Also, the tensile and yield strength is higher than 5086 alloy, so often these properties too are used by designers for their aluminum vessels. This alloy also has good welding capabilities for fabricating vessels. 5083 is also in inventory as H32 temper which is a good standard engineering alloy, but it does not have the corrosion resistance of the other special marine tempers.

Applications

• Shipbuilding, Pressure Vessels and General maritime fabricated products.
• require a weldable alloy of high to moderate strength, with good corrosion resistance.
• Commonly used in the manufacture of unfired, welded pressure vessels, marine, auto aircraft cryogenics, drilling rigs, TV towers, transportation equipment, and in missile components, drilling rigs, armour plate.
•  Its  high corrosion resistance, especially salt water corrosion resistance, makes it an excellent material for marine and processing applications.
• 5083 aluminum sheet performs well in extremely cold environments without becoming brittle and is a popular material for cryogenic equipment. It is easy to form, stamp and weld. 5083 has high resistance to corrosion, and is used in marine applications.
