5086 Marine Aluminum Sheet
The density of aluminum alloy is low, and the aluminum structure can reduce the center of gravity of the ship, especially the ship whose superstructure is made of aluminum and the main hull is made of steel, increase the stability and reduce propulsion power under the condition of constant speed.
Aluminum alloy is non-magnetic, weldable, and easy to form. Compared with steel and titanium alloys, it has no low-temperature brittleness and is non-flammable. Aluminum-magnesium alloys and aluminum-magnesium-silicon alloys have good marine atmospheric corrosion resistance, and their ship life is significantly longer than that of steel ships.
Since the end of the 19th century, marine aluminum sheets have been gradually applied in the fields of shipbuilding and marine engineering. The 5 series aluminum alloys are mainly Al–Mg series, which are divided into different grades according to the content of Mg alloys.
The relatively high content (3.5 wt.%) of supersaturated solid-solution Mg atoms and other elements in the 5-series aluminum alloy can cause serious intergranular corrosion. Warmer seawater also facilitates this process. Laser peening technology uses a laser with high pulse energy and peak power to form plasma on the surface of the material, and the rapidly generated plasma generates high-intensity shock waves in the material, thereby improving the fatigue resistance of the material.
5086 alloy is a typical one. What are 5086 aluminum properties? 5086 aluminum sheet belongs to the 5 series Al-Mg alloy, and the magnesium content generally does not exceed 7%. With the increase of the magnesium content, the strength of the alloy will increase, and the plasticity will decrease. Due to the effect of magnesium, the density of 5086 anti-rust aluminum plate is much higher than that of other aluminum plates, and it has very good corrosion resistance.
Most of the 811.30 t aluminum alloys used in the superstructure of the US Navy's first ballistic missile destroyer "Dewey" are 5466 thick plates and 5086 thin plates. The United States built the "LARC-15" landing craft with aluminum alloy. The main material is 5086, and some welding structures are 5083 and 6061.
