Aluminium In Marine Environment
The design of shipbuilding follows the idea that the structure tends to be lighter. It is widely believed that light ship structures have great advantages in controlling ship speed, operating precision, and manufacturing costs. They can minimize consumption and extend the mileage of ships. Aluminium marine can well meet the lightweight requirements of ships.
Marine aluminum plates are soaked in water all the year round and require high corrosion resistance. Aluminum alloys for ships are mainly aluminum-magnesium alloys, aluminum-magnesium-silicon alloys and aluminum-zinc-magnesium alloys.
Aluminium in marine environment need to undergo hot and cold processing and welding during processing. Ships will be impacted by waves and corroded by sea water, sea mud, and marine atmosphere during use. Therefore, marine materials are required to have high comprehensive performance, including good plasticity and weldability, high stiffness, strength, good plasticity and impact toughness, and good corrosion resistance.
Small yachts in freshwater lakes are generally made of 5052H32 aluminum plate or 5052 O aluminum sheet. Because they are exposed to fresh water, the corrosion is not as strong as seawater, so 5052 aluminum alloy is used to make them. Almost all ocean yachts are luxury yachts. Due to the strong corrosion of seawater, they are generally made of high-magnesium alloys such as 5083H116 or 5083H321 marine grade aluminum for sale.
The advantages of 5083 aluminum plate applied in the shipbuilding field lie in its high strength, corrosion resistance, plasticity and excellent welding performance. In the 1960s, with the advancement of science and technology, the production costs of aluminum sheets gradually decreased.
Aluminum for marine use can be produced by Class-approved ingot molds and continuous or semi-continuous casting methods. Marine aluminum plates should be manufactured by hot rolling or cold rolling according to their mechanical properties, profiles should be manufactured by extrusion, and pipes can be manufactured by extrusion or drawing. Haomei Aluminum has rich alloys of marine aluminum sheets and profiles. Welcome to leave message below to inquire what you need.
