5086 H32 marine grade aluminum for shipbuilding / aluminium sheet
Marine aluminum alloy according to the different manufacturing process can be divided into deformation aluminum alloy and casting aluminum alloy, because of the Marine aluminum alloy on the strength, corrosion resistance,weldability has special requirements,aluminum magnesium alloy in the most widely used in ships.The main alloy is 5083.5086.5456

Other Marine aluminium alloy
Type | Alloy | Temper | Features | Applications |
Body | 5052 | O,H14,H34 | Medium strength, good corrosion resistance and formability, strong fatigue strength | Superstructure, auxiliary construction, small boat hull |
5083 | O,H32 | Typical welding aluminium alloys, highest strength in non-heat treated alloys, weldability, corrosion resistance and low temperature type | Hull main structure | |
5086 | H32,H34 | Same welding and corrosion resistance as 5083, lower strength, improved extrusion performance | Hull main structure (thin-walled wide extruded section) | |
5454 | H32,H34 | Strength 22% higher than 5052, good corrosion resistance and weldability, general formability | Hull construction, pressure vessels, piping, etc | |
5456 | O,H321 | Similar to 5083, but slightly higher strength, stress corrosion sensitivity | Hull and deck | |
6061 | T4,T6 | Heat treatment can strengthen the corrosion resistant alloy, high strength, but low welding joint strength, mainly used for the sea water does not contact the screw joint, riveted structure | Superstructure, clapboard structure, frame, etc | |
Fittingout | 1050 1200 | H112,O,H12,H24 | Low strength, good machinability, weldability and corrosion resistance, high surface treatment | Inter finish |
3003 3203 | H112,O,H12 | Strength 10% higher than 1100, good formability, weldability and corrosion resistance | Inside, roof and side panels of LPG |
