Different tempers of 5083 Marine Ggrade Aluminum Plate 5083-h116 and 5083-H321 aluminum plates have better corrosion resistance and are more suitable for the underwater environment of the ocean than H111 and H112 temper. Although the temperature of 5083H116 and H321 aluminum sheets are slightly different in the production process, the corrosion resistance is significantly better than other tempers. Applications of 5083 Aluminum Plate 5083 marine aluminum plate is a typical Al-Mg-Si alloy with high corrosion and rust resistance. The underwater part of the hull, especially in the sea water, must be able to resist the corrosion of seawater. The most commonly used ones are 5083-H116 and 5083-H321 aluminum sheets. The keel is a longitudinal member connecting the bow post and the stern post in the center of the base of the hull. 5083 aluminum sheet is the common choice. 5083 aluminum plate is mainly used in the deck, engine pedestal, side of the ship, and the outer plate of the bottom of the ship. 5083-H116 aluminum sheet is also used in transportation field, such as automobile and aircraft fuel tank, etc.
