5xxx series marine grade aluminum plate
Where is marine grade aluminum plate used?
Marine grade aluminum plate is a very obvious application for shipbuilding. In fact, it has another application for offshore oil rigs. Offshore oil rigs have a very important position in the offshore industry. They mainly use steel structures with obvious advantages. But the shortcomings are also obvious, there are problems of rust and high maintenance costs. Therefore, it is of long term significance, which for the development of marine engineering equipment to find a new material with similar strength to steel, good durability and beautiful appearance. Marine grade aluminum is such a material. It has the advantages of light weight, high strength, corrosion resistance, low maintenance cost and recyclability.
Most marine grade aluminum plates are 5xxx series
If the 6xxx series aluminum alloy is used in seawater, intergranular corrosion will occur, so it has been widely used in the ship’s upper layer structure. The disadvantage of 7xxx series aluminum alloys is poor corrosion resistance, so its application range is limited. Generally speaking, 5xxx series marine grade aluminum plate is the most widely used and most promising marine grade aluminum plate. Usually used as hull structure or pressure vessel, pipeline, hull and deck.
Marine grade aluminum plate 5083
The high toughness, corrosion resistance and weldability of marine grade aluminum 5083 provide a good choice for the demanding ship types. The main alloy element of marine grade aluminum 5083 is magnesium, which has good corrosion resistance and weldability, and dielectric strength. Marine grade aluminum 5083 is used for hull and ship side. Common tempering is 5083-h116/h321/h112. Mingtai Aluminum marine grade aluminum 5083 has passed CCS certification, DNV certification, ABS certification, BV certification, LR certification, and has been successfully used in yacht and cruise ship hulls.
Marine grade aluminum plate 5086
The strength of marine grade aluminum 5086 is higher than 5052 and 5083. Its mechanical properties change significantly with changes in hardening and temperature. Marine grade aluminum 5086 cannot be strengthened by heat treatment. On the contrary, it will become stronger due to strain hardening or cold working of the material. Marine grade aluminum 5086 has good welding performance and maintains most of its mechanical strength. The excellent performance makes 5086 very popular in marine applications. In addition, it is also easy to form, stamp and weld.
Marine grade aluminum plate 5454
Marine grade aluminum plate 5454, this alloy is mainly used in areas requiring good formability. Commonly used tempering is o, h112, h32, h34. Comply with national standards and specifications, it is an ideal choice for large pressure vessels and certain marine products. In o soft temper, the moldability reaches the best state, but sometimes h32 or h34 temper is also used. However, strength and corrosion resistance are not always better than other alloys. Therefore, if you need marine grade aluminum plate, please tell us the specific parts you use, we can help you recommend the suitable marine grade aluminum plate alloy.
