The Properties of 5083 Plate
5083 plate is a commonly used aluminum plate in the shipbuilding. It is of stable performance, which can resist the corrosion of the atmosphere, steam, water and other media in the ocean climate for a longer period. Its low density, high strength, high rigidity and corrosion resistance make aluminum ships 20% lighter than ships built with steel or other alloy materials.
5083 aluminum alloyhas excellent corrosion resistance and welding performance, coupled with high strength, which is specially designed for welding structures that require maximum welding strength and efficiency. It can be anodized to increase the corrosion resistance.
