日本马埸义雄与字野照生发明一种弯曲成形性能优异、强度高、伸长率大。加工性能良好的铝合金。该合金板材特别适合于制造小轿车车身。当前使用的轿车车身铝合金的强度与冷轧薄钢板的虽然差不多,但其弯曲成形性能则较低,而新研制的这种合金属铝—镁—锌系合金,是一种可热处理强化的合金,其突出特点是既有相当高的强度
Japan Masahiro Yoshio and Yoshino Mori invented a bend forming performance, high strength, high elongation. Good processing performance of aluminum. This alloy sheet is particularly suitable for the manufacture of car bodies. The currently used car body aluminum alloy is similar in strength to the cold-rolled steel sheet, but its bending formability is relatively low. The newly developed aluminum-magnesium-zinc alloy is a heat-treatable Alloy, its salient features are both very high strength
