镀铝板是具有良好抗腐蚀性、耐热性和热辐射性等性能的材料，与同样镀层厚度的镀锌钢板相比，耐蚀性提高3—6倍。与车体惯用的不锈钢、铸铁等材料相比，因满足了轻量化、高性能和低成本的汽车钢的需求，越来越受到汽车制造商青睐，广泛应用于汽车排气管、发动机隔热罩等车体部件。

Aluminium-plated plate is a material with good corrosion resistance, heat resistance and thermal radiation properties, compared with the galvanized steel plate with the same coating thickness, the corrosion resistance is improved by 3-6 times.Compared with the usual stainless steel, cast iron and other materials of the car body, because it meets the needs of lightweight, high performance and automotive steel, low cost, widely used in automobile exhaust pipe, engine insulation hood and other car body parts.

镀铝锌钢板由于其合金镀层中既含有铝,又含有锌,因此除了锌的牺牲性保护外，铝元素还提供钝化保护。铝在空气中极易氧化，形成的AI2O2是一层极其致密的保护膜，可以隔绝空气中的氧气、水及其它腐蚀性物质接触到钢板表面，起到抗腐蚀作用.而锌元素则提供牺牲性保护，保护因切边或刮痕而暴露在外的钢板基板，降低其腐蚀速度。所以，镀铝锌合金镀层能提供钢板双重保护。

Aluminized zinc steel plate contains both aluminum and zinc in its alloy coating, so the aluminum element also provides passivation protection in addition to the sacrificial protection of zinc.Aluminum is easy to oxidation in the air, formed AI2O2 is an extremely dense protective film, can isolate the oxygen, water and other corrosive substances in the air into contact with the surface of the steel plate, play an anti-corrosion effect. Zinc, on the other hand, provides sacrificial protection against the steel plate substrate exposed by edge cutting or scratches and reducing its corrosion speed.Therefore, aluminum-plated galvanized alloy coating can provide double protection of steel plate.

高端家电用镀铝板具有良好的耐热性、耐腐蚀性及机械加工性能，表面涂层具有持久的光泽和优异的抗风化性。

Aluminium-plated plate for high-end home appliances has good heat resistance, corrosion resistance and mechanical processing properties, and the surface coating has lasting luster and excellent weathering resistance.

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的，性能比较的稳定，无论做什么拉伸的动作或者是各种形状的加工，它本事也有着这方面的特点，所以镀铝板就是这么任性的被大家广泛使用。

Aluminized plate has been used a lot of us, it has its own unique advantages, in processing, its heat resistance is high, can be in a heat resistant object surface form a protective film, and it is more corrosion resistance, more stable performance, no matter what stretching action or various shapes of processing, it also has this characteristic, so aluminum plate is so capricious is widely used.
