锌铝镁镀层钢板是什么？
What is the zinc, aluminum and magnesium coated steel plate?
简单来说，锌铝镁镀层钢板作为已广泛应用的热镀锌钢板的升级产品，其是通过在原热镀锌钢板镀层中加入适量的铝和镁元素制成的三元合金高耐蚀钢板。而采用锌铝镁镀层钢板生产的汽车车身在复杂恶劣的使用环境中具有更长的寿命。
Simply put, zinc aluminum magnesium coated steel plate, as a widely used hot galvanized steel plate, is made of ternary alloy high corrosion resistance steel plate made of adding an appropriate amount of aluminum and magnesium in the original hot galvanized steel plate coating.The car body produced by zinc, aluminum and magnesium coated steel plate has a longer life in the complex and harsh use environment.
目前这一技术主要应用于车身内板方面，长城汽车在自主品牌阵营中先人一步，联合首钢集团已完成锌铝镁钢板的成功开发并应用于车身组件之上，以2019款哈弗M6(国Ⅵ)车型为例，目前其全系车型在车门内板、机盖内板部分均已采用锌铝镁钢板。
At present this technology is mainly used in the body plate, the Great Wall in the independent brand camp, joint shougang group has completed successfully developed and applied to body components, in 2019 harvard M6 (countries) models, for example, the entire models in the door plate, cover plate have been adopted zinc aluminum magnesium plate.
锌铝镁镀层钢板的高耐蚀性优势根据其在车身所应用的部位可以大致细分展现为切口耐蚀、平面耐蚀、漆膜耐蚀、电偶耐蚀等方面，对应着汽车车身腐蚀问题的方方面面，包括切口腐蚀、外观件膜下腐蚀、隐藏件穿孔等情形。
The high corrosion resistance advantages of zinc aluminum and magnesium coated steel plate according to the parts used in the body can be roughly subdivided into incision corrosion resistance, plane corrosion resistance, paint film corrosion resistance, electric couple corrosion resistance, corresponding to all aspects of the automobile body corrosion problem, including incision corrosion, appearance under the film corrosion, hidden perforation, etc.
