The Application of Marine Aluminum Sheet Metal in Boats
In 1954, the Aluminum Institute of America registered 5083 marine aluminum sheet, which is regarded as an essential material for ships. Since 5083 aluminum sheet has high strength, corrosion resistance, good plasticity and welding characteristics, it uickly gained popularity in the shipbuilding industry.
Aluminum 5083 chemical composition
Alloy | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Zr | Unit |
5083 | ≦0.4 | ≦0.4 | ≦0.1 | 0.40-1.00 | 4.00-4.90 | 0.05-0.25 | ≦0.25 | ≦0.15 | - | Wt% |
In the ship design industry, 5083H116/H321/H112 are mostly used, and they are used in the main deck of the ship, the diesel engine pedestal, the side of the ship, and the outer side of the ship. 5083H111 and 5083H112 belong to the same 5083 aluminum alloy. The two are essentially the same, and there is no difference in chemical composition.
Many foreign speedboats are built with 5083 aluminum alloy. 5083 aluminum alloy has been widely used in many aspects such as military and civilian passenger ships. 5083-H116 aluminum alloy plate is the most widely used military and civilian aluminum alloy in the field of ships, and has broad application prospects in the fields of military speedboats and high-speed passenger ships.
Although 5052 aluminum is 5083 can provide about 1.5 times the tensile and yield strength than 5052. 5083 aluminum alloy also has very good welding properties. According to ESAB (a major international welding equipment manufacturer), compared with other aluminum alloys, 5083 will only lose 7% of its tensile strength around the welding zone, and 5052 will lose 19%~36% after welding of tensile strength.
5086 aluminum sheet belongs to the 5xxx Al-Mg alloy and the magnesium content generally does not exceed 7%. With the increase of the magnesium content, the strength of the alloy will increase, and the plasticity will decrease. 5086 aluminum sheet is usually used in the annealed state, cold hardened or semi-cold hardened state.
The Norwegian Shipbuilding Association stipulates the use of 5454 aluminum alloy, and the tensile strength of its aluminum plate is the same as that of 5086 aluminum alloy. In the United States, 5456 aluminum alloy is mainly used, but recently 5086-O aluminum alloy sheet and 5086-H111 aluminum alloy extruded profile are used in high-speed boats.
