◆Why Choose Marine Aluminium Sheet for Yacht-shipbuilding
Yachts are high-end durable consumer goods for water entertainment. It integrates navigation, sports, entertainment, leisure and other functions to meet the needs of individuals and families to enjoy life. Marine aluminum sheet is one of the main materials for yacht-shipbuilding. It has the following advantages:
● Durable: Aluminum will not rust, corrode or rot, and can withstand temperatures of minus 200°C, which means that your aluminum alloy yacht can withstand harsh weather wherever it goes.
● Light weight and strong anti-shock ability: The yachts made of aluminum alloy have faster speeds and consume less fuel due to light weight. At the same time, aluminum has excellent strength and anti-shock ability, making aluminum boats more resistant to foreign objects than other materials.
● Safety: Safety at sea is the primary consideration for every shipowner. Aluminum will not burn or catch fire in the atmosphere. Given the advantages and functionality provided by aluminum, many navies and coast guards use aluminum boats.
● Long service life: If the suitable aluminum alloy and welding wire are used and the ships are of standard construction and regular maintenance, an aluminum yacht can last for decades.
● High comfort: Aluminum yachts are much stronger than wooden or fiberglass yachts. Because of this, aluminum yachts can make you feel a quieter sailing experience.
◆Alloys of Marine Grade Aluminum for Yachts
The main two alloys for making yachts a re 5052 and 5083 aluminum sheets. Marine grade aluminum 5083 has high magnesium content, which is more brittle and hard, but has better corrosion resistance and higher strength than 5052 aluminum plate. 5052 aluminum sheet has better molding performance, and is better for pressing.
The small yachts in freshwater lake are generally made of 5052H32 aluminum sheet and 5052 O aluminum sheet for the fresh water is not as corrosive as sea water. Almost all marine yachts are luxury yachts. Due to the strong corrosiveness of seawater, they are generally made of 5083H116 or 5083H321 aluminum sheet.
In order to adapt to the sea water environment and beautiful appearance, some ship building factory will use 5083 aluminum as the lower part of the boat (underwater part) and 5052 as the upper part of the boat.

The aluminum plates for fishing boat mainly covers 5052, 5083, 6061 and 6063. Their choice depends on the scale and the applicable parts of the fishing boat. Generally, 5052-H32, 5052-H34, or 6061-T6 is used for small hulls that need no stretch forming.
The smaller boats using riveted construction of 5052 or 6061 alloy, and larger fishing boat using all-welded construction in 5086. The most popular alloy for hulls is 5086-H32, in thicknesses of 0.45 to 12.7 mm. 5086 aluminum plate is more expensive, but it is also much stronger than 5052.
Some fishing boats are built of 0.25-in.-thick 5052 H32 aluminum sheet and 6061-T6 shapes. Extrusions of 6061 or 6063 aluminum alloys are used for structural and decorative sections, such as keels, chines, gunwales, and spray rails.
◆Advantages of Marine Aluminum Plate
⒈ High recycling value: It can be reused repeatedly as a metal material.
⒉ Longer service life: The effective service life of aluminum alloy boats is 10 times that of FRP.

◆ Why Choose Marine Aluminium Sheet for patrol boats
⒈ Lightweight: Aluminum is a lightweight material compared to other metals used in boat construction, such as steel. This characteristic allows aluminum patrol boats to have improved speed, agility, and fuel efficiency.
⒉ Corrosion Resistance: Aluminum has excellent corrosion resistance, especially in marine environments. It forms a protective oxide layer that prevents further corrosion, making it suitable for prolonged exposure to water and saltwater.
⒊ Durability: Aluminum has high strength-to-weight ratio, which means it offers good structural integrity and durability while keeping the weight of the boat low. This makes aluminum patrol boats resistant to impacts, shocks, and fatigue.
⒋ Maintenance and Repair: Aluminum is relatively easy to maintain and repair. It doesn't require extensive maintenance efforts like painting or coating, and if the boat gets damaged, aluminum can be easily repaired or replaced.
⒌ Design Flexibility: Aluminum is a highly versatile material that allows for flexible boat designs. It can be easily welded, formed, and shaped, enabling the construction of customized patrol boats to meet specific requirements.
⒍ Longevity: Aluminum patrol boats have a long lifespan due to their resistance to corrosion and durability. They can withstand harsh marine conditions and continue to perform reliably for many years.
⒎ Cost-Effectiveness: Although aluminum patrol boats may have a higher initial cost compared to some other materials, their long-term cost-effectiveness comes from reduced maintenance, fuel efficiency, and extended service life.

◆ What Is Marine Grade Aluminum Checker Plate
Compared with ordinary aluminum alloy plate and aluminum checker plates, marine grade aluminum checker plate has stricter processes and better performance standards. Among them, Mingtai one bar aluminum checker plate has high market share in North America, especially the aluminum tread plate with a thickness of 1.6 mm or less. They have the following advantages:
⒈ Excellent corrosion resistance. Since ships are used in harsh seawater media and marine environments all year round, corrosion resistance is one of the main signs of marine grade aluminum tread plates.
⒉ It has high specific strength and specific modulus. The structural strength and size of a ship are closely related to the yield strength and elastic modulus of the material. It is usually difficult for high-strength aluminum alloys to have excellent corrosion resistance and weldability at the same time. 5xxx aluminum checker plate is often used.
⒊ Good cold and hot forming properties. Because the shipbuilding has to undergo multiple treatments such as cold processing and hot processing, the marine aluminum alloy must be easy to process and form, and still meet the requirements of strength and corrosion resistance after processing.
⒋ Excellent welding performance. At present, the automatic argon arc welding method is mainly used in ships. Good weldability means that the tendency of cracks formed during welding of aluminum alloys is small. 5XXX aluminum diamond plates have good welding crack resistance.
◆ Main Alloys of Marine Grade Aluminum Tread Plate
Aluminum alloy 5083: The surface of 5083 aluminum plate is beautiful after anodization and it has good arc welding performance. Excellent corrosion resistance makes 5083 alloy widely used in marine applications such as ships, as well as automobiles, aircraft welding parts, subway light rails, and tank trucks.
5052 marine aluminum plate: It is a widely used anti-rust aluminum. This alloy has high strength, especially fatigue resistance, high plasticity and corrosion resistance, and cannot be strengthened by heat treatment.
5086 aluminum plate: It is used in occasions that require high corrosion resistance, good weldability and medium strength, such as weldable parts for ships, automobiles and aircraft plates, pressure vessels and refrigeration that require strict fire protection Installations.
