The aluminum profile has the characters of small specific gravity and elastic modulus, corrosion resistance, easy processing and low temperature performance.
aluminum profile contains some advantages
Because of the small specific gravity, it reduce the ship weight and the engine capacity to increase the speed. Improve the ship's length-width ratio to increase the stability of the ship so that it is easy to operate; increase carrying capacity to get extra profit.
It can reduce oil and other maintenance costs to prolong service life Because of good corrosion resistance.
it is easy to carry out cutting, stamping, bending, and forming of various processing which is suitable for the hull’s streamline. It can be extruded into a large wide thin-walled profile to reduce welding number and realize the rationalization and lightweight of the hull structure.
Because of good welding performance, it can be easily welded.
Because of small elastic modulus, it can stand up to the large stress and has a greater security.
Aluminum scrap is can be recycled easily.
Because of No low temperature brittleness is most suitable for low temperature equipment.
Because of non magnetism, compass will not be affected and the whole aluminum ship can avoid mine attack that is suitable to be a minesweeper.
Because of no pest and dry, it is hardly deformed; and not burning, it is safe in fire.
Aluminum Alloy and casting Aluminum Alloy
Marine Aluminum Alloy according to the different manufacturing process can be divided into deformation Aluminum Alloy and casting Aluminum Alloy. Because marine aluminum alloys require specially strength, corrosion resistance, and so on. They usually are Al-Mg alloy, Al-Mg-Si alloy and Al-Zn-Mg alloys, among which Al-Mg alloy used in ship is the most widespread.
According to uses, the ship with Marine Aluminum Alloy can be divided into 3 kinds alloy that are relatively used in hull structure, outfitting, ship shell structure, and they are 5083 Alloy. Due to intergranular corrosion in seawater, 6000 Alloy is mainly used in the upper structure of the ship construction. Outfitting aluminum alloy is mainly used in Extruded profiles.
Types and uses of marine aluminum alloys
According to the product, Marine aluminum alloy can be divided into plates, profiles, tubes, rods, forgings, castings. Currently, the main types of companies are plate and strip.
