1. Different service life

在前面的特点部分也有提到过，铝镁锰板的耐腐蚀性好，这是因为它能和大气形成一层的氧化铝薄膜，从而使得它的寿命变久了。但是彩钢板就有所不同了，它在潮湿的环境下特别容易发生腐蚀、生锈的现象，从而引发断裂的情况。

As mentioned in the previous feature section, Al-Mg-Mn plate has good corrosion resistance because it can form a layer of alumina film with the atmosphere, thus making its life longer. But the color steel plate is different. It is particularly prone to corrosion and rust in wet environment, which leads to fracture.

2、防雷性不同

2. Lightning protection is different.

通常这两种建材多被用于外墙中，因此其防雷性也是需要考虑的，不过铝镁锰板的厚度一般为0.7-0.9㎜，可以很好的起到防雷作用;而彩钢板的厚度只有0.5㎜的钢板，防雷性不及前者，需要另设架子再预防。

Usually these two kinds of building materials are mostly used in exterior walls, so their lightning protection needs to be considered, but the thickness of Al-Mg-Mn plate is generally 0.7-0.9, which can play a good role in lightning protection; while the thickness of color steel plate is only 0.5_, which is less lightning protection than the former, and needs to be protected by another shelf.

3、强度和刚度不同

3. Different Strength and Stiffness

铝镁锰板中的铝，其强度和硬度虽然没有什么明显的屈服点，但因为还含有镁和锰这两种元素，所以就有着一定的强度和刚度。至于彩钢板，它的强度和刚度则会比前者的要好，而且不易发生变形的现象。

The strength and hardness of aluminium in Al-Mg-Mn plate have no obvious yield point, but it also contains two elements, magnesium and manganese, so it has certain strength and stiffness. As for the color steel plate, its strength and stiffness will be better than the former, and it is not easy to deform.

3、铝镁锰板的特点

3. Characteristics of Aluminum Magnesium Manganese Plate

1.可塑性好：同样也是因为主原料是铝，因此易于加工。

1. Good plasticity: It is also because the main raw material is aluminum, so it is easy to process.

2.方便安装：铝材质可以进行多种方式的连接，比如：焊接、胶粘和铆接等。

2. Easy installation: Aluminum material can be connected in many ways, such as welding, gluing and riveting.

3.环保：这种材料可回收，而且能循环利用。

3. Environmental protection: This material can be recycled and recycled.

4.重量轻：虽然是以铝为主，但密度却只有钢的1/3。

4. Light weight: Aluminum is dominant, but its density is only 1/3 of that of steel.

5强度高：通过特殊的加工和处理，使其达到很高的强度。

High strength: through special processing and treatment, it achieves high strength.

6.耐腐蚀：由于成分是铝，所以在防锈能力方面强，可形成氧化层预防被氧化和轻蚀，而且耐酸碱。

6. Corrosion resistance: Because the composition is aluminium, it has strong anti-rust ability. It can form oxide layer to prevent oxidation and light corrosion, and acid and alkali resistance.
