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.
