Alu 5086
Why Choose Marine Grade Aluminum 5086
In shipbuilding, 5083 and 5086 aluminum plates are often used for the hull, operating table and deck. The underwater part of the hull must be able to resist seawater corrosion since it keeps contact with the sea water for a long time. The harsh working environment requires the marine grade aluminum sheet have excellent corrosion resistance, high strength, excellent welding performance and good formability.
5086 aluminum sheet is an ideal choice. Its main element is Magnesium. 5086 aluminum plate has high corrosion resistance, good weldability and medium strength. The excellent corrosion resistance of 5086 aluminum plate is an important reason why it is widely used in shipbuilding. 5086 aluminum plate is also called "rust-proof aluminum plate."

The Differences Between 5083 and 5086 Aluminum Plate
Their main difference lies in the chemical composition content and mechanical properties.
The content of each chemical composition of 5083 aluminum plate: Si: ≤0.4; Cu: ≤0.1; Mg: 4.0-4.9; Zn: 0.25; Mn: 0.40-1.0; Ti: ≤0.15; Cr: 0.05-0.25; Fe: 0.4.
The content of each chemical component of 5086 aluminum plate: Mg: 3.5-4.5; Zn: ≤0.25; Mn: 0.20-0.7; Ti: ≤0.15; Cr: 0.05-0.25; Fe: 0.000～0.500.
Marine grade 5083 mechanical properties: tensile strength:110-136; elongation: ≥20, annealing temperature: 415℃; yield strength: ≥110.
Marine grade 5086 mechanical properties: tensile strength: ≥240; conditional yield strength: ≥ 95; elongation (10)%: 10 and elongation 5(%): ≥ 12.
Advantages of 5086 Aluminum Sheet
It is of light weight and excellent welding performance, contributing to the light weight and less fuel consumption and less maintenance cost.
Its elastic modulus is small, which can absorb large impact stress.
It has no low temperature brittleness, which is suitable for low temperature equipment.
Aluminum scrap has a high recycling value.
Because it is non-magnetic, the compass is not affected. The all-aluminum boat can avoid mine attack and is suitable for thunder sweeping.
It has no dry deformation and no burning when encountering fire.
