When to Choose 5383 Aluminum Plate?
You may consider choosing 5383 aluminum plate for marine applications under the following conditions:
- High Corrosion Exposure: If your project involves components that are frequently exposed to salt water or corrosive marine environments, 5383 is an excellent choice due to its superior corrosion resistance.
- Structural components: When you require high-strength aluminum for structural components of a ship, such as hulls, superstructures or bulkheads, the H116 status of 5383 is suitable.
- Welded Construction: If your application requires welding aluminum components, the weldability of 5383 may be advantageous.
Characteristics of 5383 aluminum
Since Zr is added to the 5383 alloy composition, Zr can combine with Al to form an Al3Zr phase, which can significantly increase the strength and recrystallization temperature of the 5383 aluminum alloy. Therefore, compared with 5083 aluminum alloy, 5383 aluminum alloy has higher strength and better welding performance.
The addition of Zr element only increases the production cost of 5383 aluminum alloy by about US$20/ton, so 5383 aluminum alloy has the potential to replace 5083 aluminum alloy.
