5052 Marine Grade Aluminum Sheet Metal For Boat Building
Due to aluminum's low density, high strength, high rigidity and corrosion resistance, ships built by marine grade aluminum are 15-20% lighter than ships built using steel or other composite materials. The high toughness, corrosion resistance and weldability of aluminum alloys provide a good choice for building weight-critical ships.
Marine yachts need to use 5083 aluminum plates, inland river ships use 5456 aluminum plates, and domestic park boats generally use 5052 marine grade aluminium. Their mechanical properties, corrosion resistance and welding performance are relatively superior, mainly used in the keel wing plate, curved outer plate and upper outer plate of the hull structure.
5052 aluminum sheet metal for boat building belongs to 5xxx aluminum alloy, and the Mg content is 2.2%-2.8%. It has the characteristics of light weight, medium strength, good corrosion resistance and weldability, and easy processing and forming. The tensile strength of 5052 aluminum is 230-280Rm/MP and elongation strength is 150Rm/MPa.
The application of 5052 aluminum alloy n the shipbuilding industry requires it to have high corrosion resistance against marine atmosphere and seawater corrosion. 5052 aluminum plate also has a certain anti-corrosion ability, but it cannot fully meet the application requirements of the shipbuilding industry. So it is mainly for small ships and ship parts, such as cable trays, decks, portholes, gangways, etc.
5083 aluminum is harder and has better corrosion resistance than 5052. If the ships is used in nland freshwater waters, bending 5052 aluminum can be used; If it is used in seawater or highly corrosive waters, 5083 can be used; many aluminum alloy boats will use 5083 as the lower part of the boat (underwater part) and 5052 as the upper part of the boat (surface part).
Haomei 5052 aluminum sheet has been certified by China Classification Society (CCS), Det Norske Veritas (DNV), American Bureau of Shipping (ABS), Bureau Veritas (BV), British company (LR), and has successfully entered the world shipbuilding market, and been loved by the Philippines, Myanmar, Vietnam, Thailand, Indonesia and other Southeast Asian and North American shipbuilding markets.
