The use and development trend of Mingtai marine aluminum all

Marine aluminum alloy plates are mainly used in 5 series, 6 series, and 7 series alloys. According to the aluminum structure of the hull structure and the aluminum alloy for armoring, the aluminum alloy used for the ship’s shell structure mainly has three alloys of 5083, 5086 and 5456. The 6-series alloys are intergranularly corroded in seawater, so they are mainly used in the superstructure of ships. The strength and process performance of the 7-series alloy after heat treatment is superior to that of the 5-series alloy. It has broad application prospects in the marine aluminum alloy field, and is mainly used for the superstructure of warships, such as crushed structures, armor plates, etc., but the disadvantage of the 7 alloy is the anti-stress. Corrosion performance is poor, so the range of use of the alloy is limited.
Marine aluminum alloy is the development direction of many aluminum processing enterprises in recent years. The domestic production of marine aluminum alloy enterprises has been transformed and upgraded by representatives of Chinalco, Southwest Aluminum, Nanshan Aluminum, Mingtai Aluminum, Wanda Aluminum and other manufacturers. Among them, Mingtai Aluminum is fast. In 2015, Mingtai Aluminum Marine Aluminum Alloy was awarded the 閳ユ窅hina Classification Society Factory Approval Certificate閳
