Application of Aluminum Alloys on Civil Ships
Boats are the primary means of water transportation. Due to the low density of aluminum and aluminum alloys, which is about 1/3 of steel, strong corrosion resistance to seawater, and good processability and weldability, it has been industrially produced in the United States and Switzerland since 1888. It was used in the manufacture of motorboats in its fourth year, two years before the first use of aluminum in aircraft.
In 1891, Switzerland built aluminum steamboats for the first time. After that, other countries used aluminum to build boat hulls. The metallurgical industry is the forerunner and foundation of the shipbuilding industry. With the development of the metallurgical industry, the aluminum industry provided the shipbuilding industry with Al-Mg alloys like en 5083 aluminium with high corrosion resistance in the late 1920s.
In August 1931, the United Kingdom built the "Diana II" all-aluminum yacht, the first in the world, with a silver gleam, made of aluminum-magnesium alloy. After more than 20 years of use, it is still in good condition and the hull has no corrosion. After the "Diana II", Canada, Sweden, and the United Kingdom have successively built some aluminum alloy boats.
Since 1928, aluminum alloys have been gradually used in the manufacture of superstructures of large ships, and in this year, the deckhouses were built with aluminum alloys. In 1939, the upper deck, portholes and railings of the Norwegian cargo ship "Fernplant" with a cargo capacity of 8,800t were all made of aluminum alloys, using 14t aluminum and omitting 40t of steel.
Marine aluminum alloys are also used to manufacture other civil ships. Some oil tankers built in the UK in the early 1950s were lined with 5054 alloys. In 1951, the British-made "Red Rose" fishing boat used 27t aluminum; in 1964, Hungary designed a 100t gold-aluminum fishing boat, and the aluminum used was mainly aluminum alloy containing 2.5%~4%Mg.
Aluminum alloys are also used on barges. In 1964, an all-aluminum barge was built in the United States. The applied aluminum material exceeded 180t. 5083 aluminum sheet and profile are both involved.
Tugboats can also be made of aluminum alloys. The American "Sauter" tugboat hull is welded with 5083 and 5086 alloys, and the manufacturing time is about 30% shorter than that of steel barges Welcome to leave message below to inquire aluminum 5083 price.
