鋅鋁鎂是合金金屬材質(zhì)，主要用作鋼鐵和鋼鐵產(chǎn)品的表面防腐處理，包括各種鋅系列鍍層和大量鋼的整體浸蝕防腐。

最初用作鋼鐵產(chǎn)品表面防腐處理的金屬是純鋅，隨著技術(shù)的發(fā)展，鋁鋅合金和鋅鋁鎂合金等合金金屬陸續(xù)出現(xiàn)，金屬層的防腐效果增大。與熱鍍鋅、

鍍鋅鋁、鋅鐵合金等傳統(tǒng)鍍層相比，鋅鋁鎂鍍層具有更優(yōu)異的耐腐蝕性能。鋅鋁鎂鋼板鍍層中添加了Al、Mg及Si等合金元素，

大大提高鍍層腐蝕抑制效果，與普通的鍍鋅產(chǎn)品相比，鍍層附著量少卻能實(shí)現(xiàn)更出色的耐腐蝕性。

Zinc aluminum magnesium is alloy metal material, mainly used as the surface corrosion treatment of steel and steel products,

including various zinc series coating and a large number of steel overall immersion corrosion.

The metal originally used as the surface anticorrosion treatment of steel products is pure zinc. With the development of technology,

alloy metals such as aluminum zinc alloy and zinc aluminum magnesium alloy appear one after another, and the anticorrosion effect of the metal layer has increased.Compared with traditional coatings such as hot-dip galvanizing, galvanized aluminum, zinc and ferroalloy, zinc,

aluminum and magnesium coating has more excellent corrosion resistance.Al, Mg and Si are added to the zinc, aluminum and magnesium steel plating,

which greatly improves the coating corrosion inhibition effect. Compared with ordinary galvanized products,

the coating attaches less but can achieve better corrosion resistance.
