Marine Grade aluminium alloys Supplier
As salt water is highly corrosive, assets in the marine industry like ships and offshore drilling platforms need use special materials that can withstand these conditions.
Thanks to its durable properties, marine-grade aluminum is particularly well-suited for boat building and equipment. At Jianglin, we supply a wide range of aluminum alloys.
Property of Aluminum Alloys used in Marine industry
Thanks to their low density, high specific strength, excellent elasticity, outstanding ductility, and high corrosion resistance, aluminum alloys are widely used in marine industry
high strength-to-weight ratio
Marine-grade aluminum features an exceptional strength-to-weight ratio, weighing about one-third as much as steel while providing comparable strength. For instance, 5083-H116 aluminum can achieve a tensile strength of around 317 MPa.
This results in lighter marine vessels, enhancing fuel efficiency and increasing payload capacity.
Strong corrosision resistance
Marine-grade aluminum is distinguished by its outstanding corrosion resistance. While standard aluminum corrodes at a rate of 0.1–0.2 mm per year in seawater, marine alloys like 5083 corrode at a much slower rate of about 0.02–0.03 mm per year.
Ease of Fabrication
Marine-grade aluminum provides exceptional fabrication flexibility compared to steel. Its lower modulus of elasticity, typically around 69 to 73 GPa, allows for greater ease in cold-forming processes.
Moreover, its thermal conductivity (117–167 W/mK) helps disperse heat during welding, reducing the risk of distortion.
Common Marine-Grade Aluminum Plate/Sheet

5083 Alloy
5083 aluminum plate offers excellent anti-rust properties, making it highly suitable for marine and humid environments. Common tempers used include O, H111, H112, H116, and particularly 5083-H321

5086 Alloy
Belongs to 5 series of rust-proof aluminum, commonly used state including O, H111, H112, etc., because of its high corrosion resistance, it is also widely used in shipbuilding.

5052 Alloy
5052 is a non-heat-treatable alloy known for its superior fatigue strength. It offers excellent workability for shaping into complex forms and delivers strong corrosion resistance against saltwater and atmospheric conditions.

7075 Alloy
7075 Aluminum Plate is also often used in shipbuilding due to its high strength and excellent mechanical properties, especially in parts that need to withstand high loads and harsh sea conditions

6061 Alloy
Aluminum 6061 sheet is ideal for marine applications, offering excellent corrosion resistance and robust mechanical properties. In its annealed state, it provides strong workability, and is well-suited for a wide range of near-water applications.

6082 Alloy
Belongs to 6×××× series (Al-Mg-Si) alloy aluminum plate, with medium strength and good welding performance, corrosion resistance, applicable to transportation and structural engineering, including shipbuilding

Aluminum Checker Plate
Marine-grade aluminum checker plate is commonly used for ship decks due to its superior anti-skid properties and outstanding corrosion resistance. The main alloys used are 5052, 5086, and 5083.
