产品概述

镀锌铝镁是一种新型的高耐腐蚀性涂镀产品。其镀层成分以锌元素为主,并添加铝和镁元素的含量在1.5%-8% 之间(镁元素含量总体不小于0.2%),添加的镁(Mg)成分有利于促进生成状态非常稳定且组织缜密的细致保护膜—水锌矿(Zn5 (OH)8Cl2 ‧H2O),在镀层表面生成并维持膜状的覆盖层,从而保证优异的耐蚀性。相较于传统的镀锌或者镀铝锌产品,镀锌铝镁拥有更优异的切口耐腐蚀性、平面耐腐蚀性、低摩擦系数以及耐磨损性能,可以作为彩涂板的基板,并广泛应用于汽车配件、空调、太阳能光伏支架、畜牧业、高速护栏、电气柜及钢结构建筑的屋墙面材料等。


产品特性

  • 1

    通过添加镁铝合金元素,锌铝镁镀层平面耐蚀性能大约是纯锌镀层的3倍


  • 2

    锌铝镁镀层的摩擦系数比纯锌镀层低15%, 而且在往复摩擦过程中保持稳定,因而具有优异的成形能力


  • 3

    与铝或不锈钢等产品相比,镀锌铝镁是更加经济的替代品
