5086 aluminum alloy belongs to aluminum-magnesium alloy, because the alloy composition has increased the corrosion resistance performance, so 5086 aluminum is also known as rust-proof aluminum. According to the content of the magnesium alloy, the order of the aluminum-magnesium alloy is 5005, 5252, 5251, 5050, 5052, 5754, 5083, 5056, 5086 and so on. The main component of 5086 aluminium alloy is Mg, so 5086 aluminum can produce 5086 aluminum plates and thick aluminum plates with anti-slip and anti-rust functions.
Due to its high corrosion resistance, good weldability and medium strength, 5086 aluminum sheet are commonly used in ship, automobile and aircraft plate welding parts. The products processed by 5086 aluminum alloy can also be used in pressure vessels, refrigeration units, television towers and transportation devices that require strict fire protection. The 5086 aluminum plate is the typical product of marine grade aluminum and has entered the shipbuilding market, it is mainly used for components such as decks, engine pedestals, ship sides and ship’s outer plates. The high toughness, corrosion resistance and weld-ability of marine aluminum alloys make it possible for a stringent ship type production. At the same time,  the shipboard can resist the corrosion of atmosphere, steam and water in marine climate for a longer period of time. The tempers of 5086 aluminum plate are O, H112, H116, H111, H321, H32, H36, H38, the thickness can be 0.15-600mm, the width can be 20-2600mm and the length can be 500-16000mm.
