5083 marine grade aluminium plate for shipbuilding Principal Design Features 5083 Aluminum Sheet & Plate has exceptional thermal conductivity and higher strength than 5052 . It is highly resistant to attack by seawater and industrial chemicals and is very suitable for Welding. 5083 retains exceptional strength after welding and is easily. Applicationaluminium Plate is used in heavy-duty applications in the aerospace, machinery, and transportation markets.Aluminum plate, machined to shape, forms the skins of jumbo jets and spacecraft fuel tanks.It is used for storage tanks and containers in many industries and, because many aluminum alloys actually gain strength at supercold temperatures, it is especially useful in holding cryogenic (very-low-temperature) materials.Plate provides structural sections for rail cars and large ships, as well as armor protection for military vehicles and trucks that carry payroll.
