The five grades of aluminium veneer on the market are divided into

The five grades of aluminium veneer on the market are divided into:

　　First, the manganese and magnesium content in aluminium veneer is less. So its strength and stiffness are significantly lower than aluminum-magnesium veneer and aluminum-manganese veneer. Because of its soft, easy to process, as long as it reaches a certain thickness, basically can meet the most basic flatness requirements of the ceiling. However, its resistance to oxidation is significantly less than that of aluminium-magnesium veneer and aluminium-manganese veneer. And processing transportation and installation process is easy to deformation.

　　Secondly, the raw material of this kind of plate is aluminum processing factory will dissolve aluminum ingot tied into aluminum plate, not control the chemical composition at all. Due to the chemical composition out of control, the performance of these materials is extremely unstable, resulting in serious unevenness of the product surface, product deformation, and very easy to oxidation.

　　Third, aluminum magnesium veneer while containing some manganese, the biggest advantage of the material is good oxidation resistance, while because of the content of manganese, so has a certain strength and stiffness, is the most ideal material to do the ceiling. The domestic southwest aluminum factory aluminum processing the most stable performance.

　　Fourth, ordinary aluminum veneer used in the mechanical properties of the material is less stable.

　　Fifth, aluminum manganese veneer the strength and stiffness of the material is slightly better than aluminum magnesium veneer. But the oxidation resistance is slightly lower than the aluminium-magnesium veneer. If both sides are protective treatment, basically solve its anti-oxidation ability is not as good as the shortcomings of aluminum-magnesium veneer, aluminum processing performance is the most stable.
