5083 aluminum sheet belongs to the 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. In addition, it is worth mentioning that the 5083 aluminum sheet has good resistance to seawater and low-temperature characteristics. Therefore, 5083 aluminum sheet has become the most suitable choice for marine-grade aluminum.

Applications and Features
1. Excellent Corrosion Resistance.5083 aluminum sheet can effectively resist the corrosion from the atmosphere (including marine steam and industrial atmosphere), freshwater, seawater, neutral inorganic salt solution, most acids, and organic matter.
2. Good Weldability. No matter what kind of welding method, such as gas welding, arc welding, contact spot welding, and wires welding, etc.,5083 aluminum sheet can show good weldability.
3. The 5083 aluminum sheet has good formability and high fatigue strength. However,5083 aluminum sheets can not be strengthened by heat treatment, and its plasticity is good when it is semi-cold-work hardened, its plasticity is low when it is cold-work hardened, and its machinability is general and other characteristics.
