5086 marine grade aluminum plate

Marine plate is one of the emerging areas of aluminum alloy products, and is also the focus of transformation and upgrading of many domestic aluminum processing enterprises. Since marine aluminum plate is used in marine ships and other fields, it has stricter process requirements and performance standards than other ordinary aluminum alloy products.

5086 marine grade aluminum plate

一 (1) Features of 5086 marine aluminum plate
5086 marine antirust aluminum plate belongs to the 5 series Al-Mg alloy, and the magnesium content generally does not exceed 7%. As the magnesium content increases, the strength of the alloy will increase and the plasticity will decrease. For hardened or semi-cold hardened use.
Classification of 5086 marine aluminum plate
Due to the role of magnesium, 5086 anti-rust aluminum plates can be divided into three categories according to the magnesium content, including low magnesium content, medium magnesium content, and high magnesium content.
1. The lower magnesium content is non-heat-strengthened, low-strength aluminum alloy, which has good weldability and performs well in the marine environment.
2. Rust-proof aluminum plates with medium magnesium content generally have high plasticity and medium corrosion resistance in pipes and vessels.
3. Rust-proof aluminum plates with high magnesium content are generally used for ordinary welded pipes, liquid containers and other parts.
The 5086 anti-rust aluminum plate belongs to aluminum alloy products with low magnesium content and resistance to the marine environment and climate. The density of anti-rust aluminum plate is larger than other aluminum plates, and it has very good corrosion resistance.
