鋅鋁鎂鍍層鋼板是什么？

What is the zinc, aluminum and magnesium coated steel plate?

簡(jiǎn)單來(lái)說(shuō)，鋅鋁鎂鍍層鋼板作為已廣泛應用的熱鍍鋅鋼板的升級產(chǎn)品，其是通過(guò)在原熱鍍鋅鋼板鍍層中加入適量的鋁和鎂元素制成的三元合金高耐蝕鋼板。而采用鋅鋁鎂鍍層鋼板生產(chǎn)的汽車(chē)車(chē)身在復雜惡劣的使用環(huán)境中具有更長(cháng)的壽命。

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.

目前這一技術(shù)主要應用于車(chē)身內板方面，長(cháng)城汽車(chē)在自主品牌陣營(yíng)中先人一步，聯(lián)合首鋼集團已完成鋅鋁鎂鋼板的成功開(kāi)發(fā)并應用于車(chē)身組件之上，以2019款哈弗M6(國Ⅵ)車(chē)型為例，目前其全系車(chē)型在車(chē)門(mén)內板、機蓋內板部分均已采用鋅鋁鎂鋼板。

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.

鋅鋁鎂鍍層鋼板的高耐蝕性?xún)?yōu)勢根據其在車(chē)身所應用的部位可以大致細分展現為切口耐蝕、平面耐蝕、漆膜耐蝕、電偶耐蝕等方面，對應著(zhù)汽車(chē)車(chē)身腐蝕問(wèn)題的方方面面，包括切口腐蝕、外觀(guān)件膜下腐蝕、隱藏件穿孔等情形。

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.
