Boatbuilding with Marine Grade Aluminum 5052
Aluminum alloy sheets are now used more and more in the field of yachts, speedboats and civil ships. Japan used more aluminum in the manufacture of civilian ships. Before 1945, Japan used a large amount of aluminum on the bridge and superstructure of ships, mainly 2-4mm aluminum sheet and profiles.
Aluminum alloy yachts for freshwater lakes are mostly made of 5052-H32 or 5052-0 aluminum plates, while luxury yachts on the sea are generally made of high-magnesium alloy 5083H116 or 5083H321 aluminum plates. They both have good corrosion resistance after special processing. As one of the big 5052 h34 suppliers, Haomei 5052aluminum sheet has got the main certification like DNV and ABS.
Japan has been using aluminum alloys to manufacture civil ships since 1950, ranging from fishing boats, ferries, cruise ships to ocean giant cruise ships. The 1960s was a period of rapid and sustainable development of the Japanese economy, and the shipping centered on the Seto Inland Sea was extremely busy. In order to meet the needs of transportation, the shipyards in the Seto Inland Sea and the Kansai area manufactured many aluminum alloy passenger ships.
Later, due to the rapid development of the aviation industry, the land and air transportation network rapidly increased, and the water transportation was affected. The construction of aluminum alloy ships was at a low ebb.
Since the 1980s, there has been a consensus for high-speed maritime traffic, ushering in the second climax of building aluminum alloy ships. At the same time, welding technology has also made great progress, and some aluminum alloys with good weldability and corrosion resistance have appeared.
The so-called all-aluminum alloy ship means that the hull is made of aluminum alloy plates or extruded materials, and the superstructure and internal equipment use as many aluminum parts as possible. Launched in 1995, the 1994 Weipu Biasa-type large-scale high-speed ferry "Hayabusa" is a representative aluminum alloy passenger ship built during this period.
The newly built super water-jet aluminum alloy hull in Japan is divided into upper and lower layers: the upper hull has a total length of 72.0m and a width of 37.0m; the lower hull has a total length of 85.0m. The draft is 9.6m when the water blade is propelled, and the draft is 14.0m when driving without water jet. This high speed super liner is all aluminum alloy.
The aluminum alloy high-speed passenger ship refers to the speed greater than 46km/h, and the weight of the aluminum alloy hull is about 50% lighter than that of steel. Among the approximately 2,100 ordinary tourist ships in Japan in 2013, aluminum alloy boats accounted for about 32%, and among the about 350 high-speed tourist ships, aluminum alloy ships accounted for 74%, or about 259 ships.
