Why Are More and More Yachts Made of Marine Aluminum

 Most of today's yacht hulls are made of fiberglass or marine aluminum alloys. Fiberglass material has high hardness, is relatively wear-resistant, and has good corrosion resistance, but it has poor rigidity, is not resistant to shearing, and has weak anti-aging properties. The strength will be greatly reduced under long-term high temperature conditions. Yachts need to be exposed to the sun for a long time at sea, and their strength performance and hull life will be affected.

Boats made mainly of 5083 aluminum alloy can withstand greater pressure than boats mainly made of fiberglass or steel plates when struck, without breaking or deforming. EN AW 5083 o3 has high strength, strong stress resistance and corrosion resistance, and can adapt to the marine environment. At the same time, the low density and good weldability of aluminum make it very easy to process and form.

Aluminum alloy boats are lighter, 25% lighter than fiberglass boats of the same style, and save more than 20% in fuel consumption. The lighter weight can carry more people and items. Aluminum alloy yachts have good integrity, no joints and gaps, and a tight structure. They are not afraid of minor bumps. After bumps, pits will occur, but they will not leak because aluminum alloys are more durable.

Aluminum alloy plates and profiles are easy to form and manufacture. It can be processed by extrusion, rolling and other processes to improve strength, make various shapes of structural parts, and can also be welded and spliced. It has strong designability and suitable for different waters.

Aluminum alloy yachts for freshwater lakes are mostly made of 5052-H32 or 5052-0 aluminum plates. 5052 marine aluminum plates have a higher magnesium content than other alloys, so they have a good anti-rust function, which is also an important reason why 5052 marine aluminum plates are used in hulls. Magnesium has high strength, anti-rust function and corrosion resistance, which can well cope with the corrosion of seawater and freshwater. You can learn more about al 5052 properties from us.

Therefore, high-end luxury yachts generally choose aluminum alloy. Aluminum alloy boats are stronger than steel, but the hull is lighter, which can save fuel and increase speed. Aluminum will not rust, and it is easy to repair and maintain, with low maintenance costs, which can improve the utilization rate of boats.

5086 Marine Aluminum Plate

 Generally, marine aluminium plate needs to have high specific strength and specific modulus, that is, medium strength, corrosion resistance and weldability. At the same time, it also needs to have excellent cold and hot forming functions.

Since the ship is to be subjected to various treatments of cold working and hot working, the marine aluminum plate must be easy to form without cracks, and can still meet the strength and corrosion resistance requirements after processing. In view of the above requirements of marine aluminum plate, 5083, 5086 and 5754 aluminum plate stand out among many alloy aluminum plates because of their excellent performance.

In 1940, the United States built an all-aluminum speedboat; in 1945, Japan built the "Alacase" all-aluminum patrol boat. In the 1950s and 1960s, aluminum welding technology began to appear, and the United States developed 5086 and 5456 aluminum alloy sheets and profiles. At this time, aluminum alloy ships developed in large quantities. From 1966 to 1971, the United States built 14 aluminum high-speed boats, which were the first all-aluminum warships, using 5086 aluminum alloy.

At present, the aluminum alloys used in the hull structure are mainly 5083, 5086 and 5456, which have good mechanical properties, corrosion resistance and weldability. The Norwegian Shipbuilding Association stipulates the use of 5454 aluminum alloy, and the tensile strength of its sheet is the same as that of 5086 aluminum alloy. In the United States, 5456 aluminum alloy is mainly used, but 5086-O aluminum alloy sheet and 5086-H111 aluminum alloy extrusion profile are recently used on high-speed boats.

5086 aluminum plate is a typical 5xxx Al-Mg alloy, and the magnesium content generally does not exceed 7%. Relatively speaking, the application field of 5086 aluminum plate has relatively high requirements on product performance. Therefore, its processing cost is also higher than other 5 series products.

Its tensile strength σb (MPa): ≥240, conditional yield strength σ0.2 (MPa): ≥95. It satisfies the use effect in the high-end field very well. 5086 aluminum plate has good corrosion resistance, oxidation resistance and good weldability.

In China, as one of the 5086 aluminum plate suppliers, Haomei Aluminum’s marine aluminum sheet has got the certification of CCS, ABS, DNV, LR,BV,KR. Welcome to leave message below to inquire what you need.

Marine Grade Aluminum Diamond Plate

 Marine grade aluminum diamond plate is an aluminum plate with a pattern on the surface, which has long been used in large, medium and small passenger ships, cruise ships, motorboats, high-speed missile boats, patrol boats, destroyers, fishing boat, etc. It has good anti-skid effect, strong anti-rust ability and light weight.

The advantages of 5083 aluminum sheet used in the marine field lie in its high strength, excellent corrosion resistance, plasticity and excellent welding performance. In the 1960s, with the advancement of technology, the production cost of aluminum sheet was gradually reduced and it was widely used as a lightweight material. It was used to make yacht shells, hull superstructures, masts, and port infrastructure.

5083 aluminum diamond plate is a representative product of aluminum tread plates. It features high hardness, strong corrosion resistance and good rust prevention effect, of which the hardness has obvious advantages in similar products. It can be well adapted to the occasions of high strength and high corrosion resistance, and has a good application effect on ships, vehicles and working platforms.

Magnesium element is added to this series during processing. The magnesium alloy content of 5083 aluminum plate is as high as 4.5%. At the same time, the hardness of 5083 aluminum plate is higher than that of 5754 aluminum plate. Of course, 5083 aluminum plate price is relatively high.

At present, the commonly used 5083 aluminium diamond plate is 5 bar aluminum tread plate. Since the pattern on the surface of the aluminum plate is arranged in relatively parallel according to five concave and convex patterns, and each pattern presents an angle of 60-80 degrees with other patterns, so this pattern has excellent anti-slip performance.

Haomei Aluminum has the main kinds of marine grade aluminum tread plates including 5052, 5083, 5086 and 6061. Welcome to leave message below to inquire what you need. All of our marine aluminum sheets are certificated by the classification society.

The Marine Aluminum Plate for Ship Building

 The marine aluminium plate for ship building is mainly Al-Mg aluminum alloy, Al-Zn-Mg and Al-Mg-Si alloys. According to the positions used, they are divided into aluminum alloys for upper outfitting and aluminum alloys for hull structure. The upper outfitting includes includes masts, portholes, chimneys, wheelhouses, etc. The hull structure includes the bulkheads, decks, surface plates, keel, bottom plate,etc.

The commonly used aluminum alloy for potholes of ships are 6063 aluminum alloy; 6063 and 6061 aluminum alloys are are often used for masts and gangways. The common marine grade aluminum sheets used in the hull structure is relatively high, of which 5454 and 5052 aluminum alloys are the main materials for making decks.

Application on LNG Cargo Ship

LNG cargo ships are the main ways of transporting natural gas for long distance. When designing LNG ship storage tanks, it is necessary to ensure that liquefied natural gas does not leak, ignite, and does not corrode the storage tank. Aluminum alloy is not only a low-temperature metal, but also has good strength and toughness, light weight and excellent corrosion resistance. 5083 luminum plate is often used for making LNG storage tank.

Application on Fishing Boat

There are many varieties of aluminum alloy fishing boats, suitable for different waters. It has a thick shell, which has super high strength and safety. Aluminum alloy boats are of light weight and obvious fuel saving effect.

The 5052-H32, 5052-H34, or 6061-T6 marine aluminum plate is used for small hulls that need no stretch forming. Where stretch forming is employed, 6061-T4 sheet, which may be subsequently artificially aged to the T6 temper, is utilized.
