Aluminum Alloy 5083 Marine Plate

The eight major elements that affect the performance of aluminum alloys are: vanadium, calcium, lead, tin, bismuth, antimony, beryllium, sodium and other metal elements. These impurity elements are the elements added during the processing depending on the purpose of the finished aluminum coil. Due to the different melting points, different structures and different compounds formed by aluminum, the effects on the properties of aluminum alloys are also different.
 1. Metal element: the influence of copper element
Copper is an important alloy element and has a certain solid solution strengthening effect. In addition, CuAl2 precipitated by aging has a significant aging strengthening effect. The copper content in the aluminum plate is usually 2.5%-5%, and the strengthening effect is best when the copper content is 4% to 6.8%, so the copper content of most hard aluminum alloys is in this range.

2. Metal elements: the influence of silicon
Al-Mg2Si alloy series alloy equilibrium phase diagram The maximum solubility of Mg2Si in aluminum in the aluminum-rich sector is 1.85%, and the deceleration is small with the decrease of temperature. In deformed aluminum alloys, the addition of silicon alone to the aluminum plate is limited to welding materials, and the addition of silicon to aluminum It also has a certain strengthening effect.
3. Metal elements: the influence of magnesium in Aluminum Alloy 5083 Marine Plate
The strengthening of aluminum by magnesium is remarkable. For every increase of 1% of magnesium, the tensile strength will increase by about 34MPa. If you add less than 1% manganese, it may add to the strengthening effect. Therefore, after adding manganese, the magnesium content can be reduced, and the hot cracking tendency can be reduced at the same time. In addition, manganese can also precipitate the Mg5Al8 compound evenly, improving the corrosion resistance and welding performance.
5083 marine aluminum plate as a ship plate advantage
5083 aluminum alloy is a high-magnesium alloy, which has good strength, corrosion resistance and machinability among non-heat-treatable alloys. The surface is beautiful after anodization. Good arc welding performance. The main alloying element in 5083 alloy is magnesium, which has good corrosion resistance and weldability, and medium strength. Excellent corrosion resistance makes 5083 alloy widely used in maritime applications such as ships, as well as automobiles, aircraft welding parts, and subway light rails.
