Marine Grade Aluminum Sheet for Ship Building
The marine grade aluminum sheet mainly refers to Al-Mg and Al-Mg-Si aluminum alloy, which is used for hull structure and upper outfitting. The hull structure includes: ship side, bottom shell, keel, ribs,bulkhead,etc. The outfitting includes wheelhouse, bulwark, chimney, porthole, mast, etc.
Many countries have adopted Al-Mg alloy as hull structural materials. From 1966 to 1971, the main deck and bottom of the finished high-speed gunboats used 5086 aluminum sheet in H32 temper. In addition, 5052 and 5454 aluminum sheets are also used for decks.
In the the superstructure, portholes are made of 6063 aluminum alloy profiles, and gangways and masts often use 6061 aluminum sheet and 6063 aluminum alloy. In the outfitting structure, an integral wall panel extruded from Al-Mg alloy is often used, which can reduce welding deformation and make the stress distribution more reasonable.
The working environment of ships requires structural materials to have certain properties such as mechanical strength, fatigue strength, elongation and impact resistance. However, it is usually difficult for high-strength aluminum alloys to have excellent corrosion resistance and weldability at the same time. Therefore, aluminum alloys for ship building generally use medium-strength corrosion-resistant weldable aluminum alloys.
Haomei marine grade aluminum sheet has high toughness, corrosion resistance and weldability, providing the possibility for strict ship-type production. At the same time, Haomei marine aluminum sheets can resist the corrosion of atmospheric, steam, water and other media in the ocean climate for a longer time.
Haomei 5083 aluminum sheet has passed the relevant certificates like DNV, ABS, NK, CCS and LR. In addition to 5083 aluminum plates, Haomei Aluminum’s 5052, 5754, 5086 aluminum sheet,etc., has been exported to dozens of countries. They are mainly used for deck, engine pedestals, ship sides, ship bottom panels,etc. Welcome to leave message below to inquire what you need.
