2A12 aluminum plate is used more in the aerospace field, mainly because of its high strength, high hardness, good plasticity and other characteristics, then what are the specific advantages and disadvantages of 2A12 aluminum plate?Next, 2A12 aluminum plate manufacturers to detail.
2A12 aluminum plate can basically reach 1.5% Mg content, and contain high Mn, S phase as the main strengthening phase, has a higher strength.2A12 aluminum plate has high strength and qualified plasticity, has high corrosion resistance, is a kind of hard aluminum widely used in aviation industry.
Major disadvantages of 2A12 aluminum plate
Because of the high Cu content, the corrosion resistance of 2A12 aluminum plate is lower than that of pure aluminum and Al-Mn alloy.Because the electrode potential containing Cu solid solution and CuAl2 is higher than the grain boundary, it is easy to cause local corrosion phenomenon.Therefore, the corrosion resistance of 2A12 aluminum plate in T4 state is very low in the ocean and humid atmosphere, which can not meet the requirements of use. Therefore, artificial intelligence protection is needed for students to study.One of the protection methods is to coat the surface of 2A12 aluminum plate with pure aluminum plate with purity greater than 99.5% by hot rolling.Because the electrode surface potential of pure Al is lower than that of hard aluminum, it plays an anodic oxidation role in the atmosphere and can form Al2O3 protective film. Therefore, 2A12 aluminum plate material itself can improve the important role of electrochemistry and mechanical protection before the aluminum coating is destroyed.
