Marine Grade 5083 Aluminium Plate

5083 aluminum sheet plate belongs to Al-Mg series alloy. It is the highest strength corrosion-resistant alloy among practical non-heat-treated alloys. And it is suitable for welding structures. Also, it is worth mentioning that 5083 aluminium sheet has good resistance to seawater and low-temperature characteristics. Therefore, 5083 aluminium sheet has become the most suitable choice for marine-grade aluminium.

Among the alloy states of 5083 aluminium sheet plate, most are H111/H112/H116/H321. Among them, the magnesium content of 5083-h116 aluminum sheet is as high as 4.9%, which is a high-magnesium alloy. It has high corrosion resistance and can resist the erosion of seawater. It is mostly used for underwater parts of ships.

The density of 5083-h116 aluminum sheet is low, only 2.66 g/cm³; the tensile strength of 5083 alloy is higher, which is higher than some low-carbon mild steel, and it is durable and has excellent corrosion resistance; 5083 h116 aluminum sheet The welding performance is also very good, and it is not easy to crack and deform after processing.

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.

The use of 5083-h116 aluminum sheet for marine aluminum sheet depends on three factors

1.  light weight.

Marine aluminum plates generally use thin plates over 1.6mm and thicker 5083-h116 aluminum sheets over 30mm. Aluminum-magnesium alloys have low density and light weight, which can reduce the weight of the hull and increase the load capacity.

2. the aspect of corrosion resistance.

5083 h116 aluminum sheet belongs to the aluminum-magnesium alloy, which is a typical anti-rust aluminum, which can adapt to the highly corrosive seawater environment for a long time.

3. The aspect of safety.

5083-h116 aluminum sheet has medium strength, good processing performance, excellent weldability, fatigue resistance, no cracks, and can still meet the strength and corrosion resistance requirements after processing, which can ensure the safety of the ship
