What Is Marine 5086 Aluminum Plate
Marine aluminum plates are immersed in water all year round and require high corrosion resistance. Marine 5086 aluminum plate has high strength and excellent corrosion resistance, making it an ideal choice for shipbuilding.
5086 aluminum plate belongs to 5XXX Al-Mg alloy. The magnesium content generally does not exceed 7%. As the magnesium content increases, the strength of the alloy will increase, while the plasticity will decrease. 5086 aluminum plate is usually used in the annealed state, cold work hardening or semi cold work hardening state. Due to the role of magnesium, 5086 anti-rust aluminum plates have a much higher density than other aluminum plates and have very good corrosion resistance.
The Norwegian Shipbuilding Industry Association stipulates the use of 5454 aluminum alloy, and the tensile strength of its plates is the same as that of 5086 aluminum alloy. The United States mainly uses 5456 aluminum alloy, but recently used 5086-O aluminum alloy plates and 5086-H111 aluminum alloy extruded profiles on high-speed boats.
Most of the 811.30t aluminum alloy used in the superstructure of the "Dewey" is 5456 alloy thick plates and 5086 alloy thin plates. After aluminum alloys replace steel, unnecessary weight is saved. Of the total amount of aluminum used, about 20% is 5456 and 5086 alloys. 5XXX series alloys have stronger corrosion resistance to seawater.
In addition, the 5086 aluminum plate with surface embossing treatment is also the best material for spiral staircases, pedals, refrigerated truck wall panels and floors on large ships. With various patterns like 2 bar, 3 bar, 5 bar,etc., 5086 aluminium plays a more important role in slip resistance.
In one test, unwelded and welded 5086 marine aluminum alloy sheets were partially and fully immersed in the waters of Toona, Florida for 5 and 7 years. After 5 years, the strength loss of fully immersed unprotected weld specimens 5086 was negligible, almost no corrosion pits were found, and the maximum corrosion pit depth was only 0.38mm. This fully demonstrates that 5086 plate maintain its inherent resistance to seawater stress corrosion. Welcome to leave message below to inquire 5086 aluminum sheet prices.
