渗铝板在热浸镀加工过程中,熔融的铝立即与空气中的氧反应形成一层Al2O3保护层,使钢板表面立即钝化。这个保护层非常稳定且不溶于水，即使后来钢板表面被划伤，这个保护层也具有自愈功能。因此，镀铝板对化学腐蚀有极强的耐蚀性。

During the hot-dip plating process, the molten aluminum immediately reacts with the oxygen in the air to form a Al2O3 protective layer, which immediately passives the surface of the steel plate.The cover is very stable and insoluble, and is self-healing even when the plate is later scratched.Therefore, the aluminized plate has a very strong corrosion resistance to the chemical corrosion.

未化学钝化的镀铝板对健康无影响，因而可用于食品加工。很多专业团体的测试报告证实其对人体无害属环保产品。镀铝板完全可以循环利用。镀铝板可以和不锈钢媲美但是价格仅为不锈钢的三分之一左右。

Unchemically passivated aluminum plates have no health effects and thus can be used for food processing.Test reports by many professional groups confirm that they are environmentally friendly.Aluminium-plated plates are fully recycled.Aluminized plate is comparable to stainless steel, but the price is only about a third of the stainless steel.

这种镀铝板之所以一直被我们大量的使用，它有着自己特有的优点，在加工的时候，它的耐热性比较的高，可以在一种不耐热的物体表面形成一个保护膜，并且它也是比较的耐腐蚀、性能稳定，可以做拉伸的动作或者是各种形状的加工，所以镀铝板就是这么任性的被大家广泛使用。

This aluminum plate has been a lot of use, it has its own unique advantages, when processing, its heat resistance is high, can be in a heat resistant object surface to form a protective film, and it is more corrosion resistance, stable performance, can do stretching action or various shapes of processing, so aluminum plate is so capricious is widely used.

镀铝钢板的用途甚广。最初开发的Ⅰ型镀铝钢板主要用于汽车的排气管和消声器。Ⅱ型主要用于建筑物的屋顶板和侧壁以及一些化工容器。新工艺生产的镀铝钢丝有望用作输电用钢芯绞线而取代目前的镀锌钢丝。镀铝钢管已大量用于电厂锅炉水冷壁管、蒸汽管道、热交换器等。镀铝钢结构尖已大量用于输电铁塔、告诉公路护栏等。

Aluminized steel plate is widely used.The originally developed type I aluminum-plated steel plate was mainly used for automotive exhaust pipes and mufflers.Type is mainly used in the building roof panels and side walls as well as some chemical containers.The aluminized steel wire produced by the new process is expected to be used as the steel core stranded wire to replace the current galvanized steel wire.Aluminium-plated steel pipe has been widely used in the power plant boiler water wall pipe, steam pipe, heat exchanger, etc.Aluminized steel structure tip has been widely used in the transmission tower, tell the highway guardrail, etc.

从长远看，由于锌资源匮乏，而铝资源丰富，镀铝钢材将成为目前应用最广的镀锌钢材的竞争对手。

In the long run, due to the lack of zinc resources, and rich aluminum resources, aluminum-plated steel will become the most widely used galvanized steel competitors.
