5000 series
marine aluminum alloy plate mainly 5083,5086,5456 these three. 6000 series alloy in the seawater will occur between the intergranular corrosion, so the ship superstructure use more, 7000 series alloy shortcomings is poor corrosion resistance, so the use of limited. On the whole, 5000 series of marine aluminum is currently the most widely used, the most promising aluminum products.
5052 aluminum plate for the AL-Mg alloy
aluminum plate, is the most widely used a rust-proof aluminum, high strength and corrosion resistance. But can not heat treatment to strengthen, in the semi-cold hardening when the plastic is still good, cold hardening when the plastic low, polished.
5083 aluminum alloy in the high strength, heat treatment of the alloy, with good machinability, corrosion resistance and welding performance. Is widely used in traffic vehicles, such as ships, aircraft, vehicles and pressure vessels (tankers, refrigerated trucks, refrigerated containers) and so on.
5754 aluminum plate with moderate strength, good corrosion resistance, weldability and easy processing and forming characteristics, is Al-Mg alloy in the typical alloy. In foreign countries, 5754 aluminum alloy sheet with different heat treatment status is the main material used in automobile manufacturing (car doors, molds, seals) and cans industry.
