Excellent stamping performance. Various types of welding can be carried out, and the welding performance is good. The welded joint can reach 90% of the strength of the substrate. It is easy to cut by saw and grinding wheel, and has good mechanical processing performance. Excellent corrosion resistance is used for parts with less than 350 ℃, low stress and parts punched into various complex shapes. Such as thermal power plant condensers; marine seawater corroded piping systems, valves, pumps; chemical heat exchangers, pump bodies, distillation towers; seawater desalination systems, platinum-plated anodes; aircraft skeletons, skins, engine parts, beams, etc.
