Marine Grade Aluminum Sheet Alloys 5083 5059
In 1891, the first steam passenger ship Le Migron was built under the guidance of Swedish scientist Alfred Nobel, which could carry 8 passengers. This is the first ship in history to use aluminum alloy. Facts have proved that aluminum alloy can indeed be applied to ships.
In 1894, the Scottish shipyard Yarrow & Co built Falcon, a 58-meter-long aluminum torpedo ship for the Russian Imperial Navy, which reached a speed of 32 knots, a record that was not broken for a long time at the time.
Although steel has many advantages, it has an unavoidable shortcoming-too heavy. For ships, weight is a very important factor because it determines the speed of travel and the weight of the transported load. The higher the speed, the greater the payload. It is well known that "light metal" aluminum can effectively reduce weight by as much as 50%, thus promoting people's research on aluminum and its properties.
In 1954, the Aluminum Institute of America registered aluminium sheet 5083, which is regarded as an essential material for ships and it is also widely used in many other fields. High strength, excellent corrosion resistance, good plasticity and welding characteristics make the marine grade aluminum 5083 quickly gain popularity in the shipbuilding industry.
Aluminum boats do not require special care like steel boats, greatly reducing maintenance costs. Usually, in order to consider a higher driving speed, for sports boats, almost all of them are made of aluminum materials from the shell to the superstructure.
The outer shell of the ship with large loading capacity is made of steel, and the superstructure and other auxiliary equipment are made of aluminum alloy to reduce the total weight and increase the loading capacity. Until now, among all aluminum alloys, 5083 alloy has almost no competitors.
In 1999, for the further development of the shipbuilding industry, the Koblenz Rolling Works (Germany) and the Aluminum Association of America registered the 5059 aluminum sheet.This alloy verifies that aluminum can be stronger than steel.
Its ultimate strength value and yield point are comparable to low alloy steel S235 (AlCu4SiMg, AA2014), and its strength characteristics are also greatly improved compared with traditional 5083 aluminum alloy. Yield point is increased by 26% and 28% after welding. Haomei Aluminum has both 5083 and 5059 aluminum sheet with certifications. Welcome to leave message below to inquire what you need.
