Machining 5083 Aluminum for Boat
Aluminum alloy has the characteristics of small specific gravity and elastic modulus, excellent corrosion resistance, easy processing, non-magnetic and low-temperature properties. With the development of the shipbuilding industry, light weight has been paid more attention, so the aluminum alloy structure is gradually replacing the traditional steel structure. The marine aluminum alloys are machining 5083 aluminum, 5456, 5086, 5454 alloys, etc.
5083 aluminium sheet is a typical 5000 series aluminum sheet. Due to its high strength, strong corrosion resistance, easy processing and welding, it is mostly used in shipbuilding, and it is also called marine aluminum plate. It is the most common aluminum sheet for the manufacturing of boats. It has stable performance, and it can resist corrosion and corrosion well in environments such as seawater and steam, and is durable. At present, most shipbuilding companies purchase directly from us.
The self-corrosion potential of 5083 aluminum plate is about -760 mV, the pitting corrosion breakdown potential is -690 mV, and the corresponding pitting corrosion protection potential is -720 mV. Cl- is the active ion that induces pitting corrosion of 5083 aluminum alloy.
For solutions with the same ionic strength as seawater, when the Cl- content is 0-0.1 mol/kg, the pitting breakdown potential decreases rapidly with the increase of the Cl- content in the solution; when it exceeds 0.1 mol/kg, the pitting breakdown potential no longer occurs obvious change.
Electrochemical cathodic protection can effectively inhibit the formation and development of pitting corrosion in 5083 aluminum alloy. In the seawater system, the suitable cathodic protection potential range of 5083 aluminum alloy is between -800~-1000 mV.
5083 h112, h116 and h321 are its common tempers, which can be used on the hulls of yachts, cruise ships, and fishing boats. Common thicknesses are 1/2/3/4/5 mm and so on. The current conventional size of the ship plate is 2000mm width and 6000/8000/9000/12000mm length, mainly large-size aluminum plates.
Haomei Hot Rolling Mill is a large-scale reversible hot-rolling coiling equipment, which can directly produce 8mm hot-rolled aluminum coils, and then gradually process them into aluminum plates through finishing rolling equipment, annealing equipment, cleaning equipment, and cutting equipment. It has the advantages of smooth surface and no oil pollution.
The content of the alloy is detected by a direct-reading spectrometer, which can better ensure the accuracy and stability of the mechanical properties and chemical composition of 5083 aluminum. Welcome to leave message below to inquire what you need.
