The 5456 Aluminum For Ship Building
Ships often sail in harsh sea water media and marine environments, so whether the materials used are corrosion-resistant is a key factor for deciding whether they can be used as the marine aluminum sheets. The aluminum sheets should have no stress corrosion, spalling corrosion, and intergranular corrosion tendency in seawater and marine environments.
Relevant experiments have proved that any small aluminum boat can be used for decades without any obvious corrosion. The exit of such ships is usually due to outdated technology, rather than the aging of the aluminum structure. Therefore, 5xxx aluminum has been recognized for its excellent resistance to marine climate, especially the resistance to seawater erosion. Among them, 5456 aluminum is a typical welding aluminum alloy.
Among non-heat-treated alloys,5456 aluminium sheet has higher strength, good weldability, corrosion resistance and low temperature performance. Its performance can fully meet the requirements of high welding structure. In addition, 5456 aluminium price is very reasonable, contributing to a low shipbuilding cost.
5456 aluminum plate can be used on the side of the ship and will not corrode for a long time. It is also mainly used on ship decks. Depending on the different tempers, it can be used in different positions such as living deck, walking deck, driving deck,etc.
The bottom shell is an integral part of the bottom structure, which is welded from many metal plates to form the shape of the bottom of the ship. Different positions of the ship's bottom plate have different stress positions. It is necessary to choose the appropriate aluminum alloy according to the position.
5456 aluminum is very suitable for being used as the bottom outer pate of the ships. Aluminum alloy 5456 has high toughness and plasticity, and the plasticity of the ship material can effectively prevent the cracks on the hull from increasing that will reduce its hardness. The weldability of 5456 aluminum plate is better than that of steel, and it is a good choice for ship building.
