以烤箱采用的内胆材质基本上就可以区分出烤箱的定位。目前市面上内胆材质大概有镀锌钢板、镀铝钢板、不锈钢板以及搪瓷钢材质，这几种材质成本由低到高，反映到烤箱上的价格也是如此。

The inner bladder material made of the oven can basically distinguish the positioning of the oven.At present, the liner material on the market is about galvanized steel plate, aluminum plated steel plate, stainless steel plate, stainless steel plate and enamel steel quality, the cost of these several materials from low to high, reflected in the price on the oven is the same.

目前来说，镀铝钢板正在逐步取代镀锌板，相对来说，镀铝板寿命更长（延长60%），且能够耐受600℃高温，拥有更好的耐腐蚀抗氧化特性。因此镀铝板可制成的隔热屏障或者在高温应用中的热反射器，通过有效的热反射使炉内温度迅速升高。机械强度：在室温下,镀铝板的机械强度与其基材的机械强度一致。在同样的480℃的高温下,镀铝钢板的强度是铝板强度的10倍因此钢板厚度可至少减少30%。

At present, aluminized steel plate is gradually replacing galvanized plate, relatively longer life (60% longer), and can withstand 600℃ high temperature, has better corrosion resistance and oxidation resistance characteristics.Therefore, aluminum plating plate can be made of heat insulation barrier or heat reflector in high temperature application, and the temperature in the furnace increases rapidly through effective heat reflection.Mechanical strength: at room temperature, the mechanical strength of the aluminum-plated plate is consistent with the mechanical strength of the substrate.At the same high temperature of 480℃, the strength of the aluminum-plated steel plate is 10 times that of the aluminum plate, so the steel plate thickness can be reduced by at least 30%.

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，所以镀铝板就是被大家广泛使用。

This aluminum 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 widely used.
