渗铝板，即镀铝板或热浸渗铝板。热浸镀铝钢材兼有钢基体的高强度和铝层的耐腐蚀、抗磨损、耐高温等特性。其耐蚀性是镀锌钢材的5-10倍；耐硫化物和耐热腐蚀方面。其性能优于18-8不锈钢。因而能给用户带来明显的经济效益。热浸镀铝钢材的用途甚广。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。镀铝钢结构已大量用于输电铁塔、高速公路护栏等。

Aluminized plate, namely aluminum plated plate or hot dip aluminum plate.Hot-dip aluminum-plated steel has the high strength of steel matrix and the corrosion resistance, wear resistance and high temperature resistance of aluminum layer.Its corrosion resistance is 5-10 times that of galvanized steel; sulfur resistance and thermal corrosion resistance.Its performance is superior to the 18-8 stainless steel steel.Therefore, it can bring obvious economic benefits to users.Hot-dip aluminum-plated steel is widely used.The Type I aluminum-plated steel plate was originally used for automotive exhaust pipes and silencers.Type is mainly used for the roof panels and side walls of buildings and some chemical containers.Aluminized wire produced by the new process is expected to be used as a core twisted wire for transmission instead of the current galvanised wire.Aluminized steel pipe has been widely used in the power plant boiler water-cooled wall pipe, steam pipe and heat exchanger.Aluminium-plated steel structure has been widely used for power transmission towers, highway guardrail, etc.

*耐蚀性+耐候性+耐海水性

镀铝钢材具有耐蚀性，其耐蚀性是通过氧化铝膜、铝层自身的耐蚀性、合金层的耐蚀性以及铝层——合金层——母材之间的电化学的防蚀原理等发挥出来的；镀铝钢材亦具有耐候性，镀铝产品能在海洋潮湿地区、工业地带及硫磺温泉等腐蚀性环境下长期使用；热浸镀铝钢材对海水有很好的防腐性，不仅在海洋环境中，就是在海面和波浪中也有同样效能。镀铝钢材耐盐水的腐蚀性十分显著。

* Resistance + weather resistance + seawater resistance

Aluminized steel has corrosion resistance through corrosion resistance of alumina film, aluminum layer itself, alloy corrosion resistance and electrochemical resistance between —— base materials of aluminum layer —— alloy layer; aluminum coated products can be used in wet areas, industrial zone and sulfur hot springs; hot dipped aluminum steel has good corrosion resistance to seawater, not only in Marine environment, but also in sea surface and waves.The corrosion resistance of aluminum-plated steel is remarkable.
