The History of 5083 Aluminum in Shipbuilding Industry
With the lightweight development of ships increasingly requires reducing the weight of the hull and increasing the speed of the ship. Aluminum alloy shipbuilding has the advantages of small specific gravity, good corrosion resistance, good processing and forming performance, good welding performance, and small elastic modulus.
The application of 5083 aluminum sheet in the shipbuilding industry has a history of more than one hundred years. Seawater is an electrolyte solution, and the corrosion process of seawater on aluminum alloy is an electrochemical corrosion process, which is specifically manifested in the form of pitting corrosion. The corrosion rate of 5000 aluminum is very low, especially the low-magnesium alloys.
5083 aluminum is widely used in the hull, keel and frame of the ships. Although 5052 can be also used on the ships and it is easier to process and shape, 5083 aluminum plate can provide about 1.5 times the tensile and yield strength than 5052.
Tensile strength refers to the maximum stress that a material can withstand before it is broken. Yield strength refers to the ability of a material to resist slight plastic deformation. Beyond this limit, the material will not be able to return to its original shape, showing permanent deformation.
Specifically, this means that under the same thickness and other conditions, a boat made of 5083 aluminum sheet can withstand higher pressure than a boat made of glass fiber, steel plate, or 5052 aluminum alloy when subjected to an impact without breaking or deforming.
5083 aluminium sheet also has very good welding performance. According to ESAB (a major international welding equipment manufacturer), compared with other aluminum alloys, 5083 will only lose 7% of its tensile strength around the welding zone, and 5052 will lose 19%~36% after welding. Heat-treated alloys such as 6061 may lose about 80% of the tensile strength around the heat-affected zone of the weld bead.
The common tempers of 5083 aluminum sheet includes 5083 h321, 5083 h111 and 5083 h116. Besides 5083 alloy, Haomei Aluminum also has 5086, 5052, 5454, 6061etc. Welcome to leave message below to inquire what you want.
