Marine Grade Aluminum Alloys
Marine grade aluminum has been used in the shipbuilding industry for nearly a hundred years. With the rapid development of domestic and foreign shipbuilding industries, With the rapid development of the shipbuilding industry at home and abroad, the lightweight of ships has been paid more and more attention. Due to the low density, high strength, high rigidity and corrosion resistance of aluminum alloys, its application in ships has obtained obvious effect.
The popular marine aluminum grades are 5083, 5086, 5454 and 5052 alloy, which are mainly for ship decks and hull parts. The wide aluminum plates are often used. The production requirements of marine aluminum plates are more stringent than other products.
5083 aluminum alloy is an alloy widely used in shipbuilding at present. It cannot be strengthened by heat treatment. The main strengthening method is work hardening. The processing technology is generally hot rolling, cold rolling and stabilization to achieve the H116 state to meet the corrosion resistance performance.
The Mg content of the 5086 anti-rust aluminum plate generally does not exceed 7%. With the increase of the magnesium content, the strength of the alloy will increase, and the plasticity will decrease. It is usually used in the annealed state, cold hardened or semi-cold hardened state. Due to the effect of magnesium, the density of 5086 anti-rust aluminum plate is much higher than that of other aluminum plates, and it has very good corrosion resistance.
Due to the different areas of use of ships, the performance requirements for aluminum plates are also different during the manufacturing process. Generally, the aluminum plates used in our common inland ships are mostly 5454 aluminum.
The machinability of 5052 aluminum sheet manufacture is also better than that of 3003 aluminum, and its seawater resistance is also excellent. Therefore, 5052 aluminum has become a commonly used marine grade aluminum plate in the shipbuilding industry. 5052 marine aluminum is mainly used for small ships and ship components, such as cable bridges, decks, portholes, gangways, etc.
All of our marine grade aluminum sheets for sale have obtained certifications from China Classification Society (CCS), Det Norske Veritas (DNV), American Ship Classification Society (ABS), Bureau Veritas (BV) and British company (LR) certification. Welcome to leave message inquire what you need.
