Why Is Marine Grade Aluminum 5086 So Popular

Marine aluminum sheets have special requirements for strength, corrosion resistance, weldability, etc., so marine aluminum sheets are mostly made of aluminum-magnesium alloys, aluminum-magnesium-silicon alloys and aluminum-zinc-magnesium alloys, of which 5xxx aluminum is widely used in the field of marine engineering.

Deformed aluminum alloys used in marine engineering include 5052 (5A02), 5252, 5154, 5454, 5754, 5083, 5086, 5059,etc. The magnesium content of the 5052 alloy is lower; the magnesium content of the 5154, 5454, and 5754 alloys is moderately low; the magnesium content of the 5083 alloy is moderately high; the magnesium content of the 5086 alloy is moderately low; the magnesium content of the 5059 alloy is the highest.

Marine grade aluminum sheet 5086 has low density, high tensile strength, high elongation,high corrosion resistance, medium strength, and good weldability. Therefore, it is more suitable for the side plate of the ship.

From 1966 to 1971, the main deck and the bottom of 14 "Asheville"-class high-speed gunboats built in the United States were made of 12.7mm thick 5086-H32 aluminum sheet. It adopts the connection method of TIG and MIG welding, preventing rivets from loosening and water seepage, solving the problem of contact corrosion, improving the connection strength by 10% to 20%, and reducing the weight by 20% to 30%.

The main alloying elements of 5086 aluminum plate are magnesium and silicon. Compared with other aluminum plate products, 5086 aluminum plate is of better corrosion resistance. It is also used in the manufacture of sheet metal parts for transportation vehicles, ships, instruments, hardware products and electrical enclosures.
