Marine Aluminum Sheet for Boat Building

Due to the low density of aluminum alloys, about 1/3 of steel, strong corrosion resistance to seawater and good processing and forming properties and weldability, aluminum alloys are not only used in aircraft manufacturing,electronic accessories, machinery manufacturing, communication equipment, electronic product processing, but also in shipbuilding.

Aluminum sheet for boat building needs to undergo hot and cold processing and welding during processing, and ships will be impacted by waves and corroded by seawater, sea mud, and marine atmosphere during use. Therefore, marine aluminum sheets are required to have high comprehensive performance, including good plasticity and weldability, high stiffness, strength, good plasticity and impact toughness, and good corrosion resistance.

General marine grade aluminum alloy refers to 5xxx Al-Mg aluminum alloy. At present, the aluminum alloys used in ship hull structures are mainly 5083, 5086, and 5456. Ocean yachts need to use 5083 aluminum plates, inland rivers use 5456 aluminum plates, and domestic park boats generally use 5052 marine grade aluminium. These three alloys have relatively superior mechanical properties, corrosion resistance and welding properties.

The Al-Mg alloy is a non-heat treatment strengthening alloy in which Mg is added alone or both Mg and Mn are added to aluminum. Alloys such as A5052 and A5083 containing 2.5% to 5% Mg can have a tensile strength of 196 to 294 MPa depending on the Mg content.

5052 aluminum plate is an Al-Mg alloy with excellent corrosion resistance and medium strength. It is suitable for the manufacture of economical aluminum alloy ships. In addition to being used for ship plates, 5052 aluminum plates can also be used for cable trays on ships, ship sink, ship floor and other parts. 5052 aluminum thickness depends on the applied part.

Haomei Aluminum can provide various thicknesses, widths and lengths of marine aluminum plates with DNV, ABS, LR or CSS certification. The popular thicknesses are 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, etc. Some large sizes like 2*6 meter, 2*8 meter or 2*12m are all in stock. Welcome to leave message below to inquire what you need.
