5083-H112 is an aluminum alloy plate for machining, a 5XXX series aluminum and magnesium alloy, with medium strength, good corrosion resistance and weldability. After anodizing, the alloy has a beautiful surface and good arc welding performance. It is widely used in all fields from thin plates to thick plates. It is one of the widely used aluminum alloy materials in the shipbuilding industry.
5083 H112 state introduction
5083H112: H1 indicates a simple work hardening state without additional heat treatment; the second digit after the work hardening code H (1-9) indicates the work hardening degree of the product; the meaning of the third digit after the work hardening code H, H112 indicates an alloy product suitable for hot processing and forming, and there are specified requirements for its mechanical properties.
Advantages of 5083 marine grade aluminum plate
1. Excellent corrosion resistance: It has strong resistance to salt spray, moisture and seawater corrosion common in marine environment, and is an ideal material for ships and marine engineering.
2. High strength: Among non-heat-treated aluminum alloys, 5083 has higher strength and is suitable for parts that bear certain pressure and load.
3. Excellent welding performance: It is easy to use TIG and MIG welding, and the performance after welding is not significantly reduced, which is suitable for welding and manufacturing of complex hull structures.
4. Good formability: It has excellent ductility and stamping performance, and is easy to process into hull structural parts with complex shapes.
5. Low density: The density of aluminum is only 1/3 of that of steel, which can effectively reduce the weight of the hull and improve the economy and fuel efficiency of the ship
