Industrial aluminum profiles can be divided into raw aluminum and wrought aluminum. Primary aluminum is less than 98% aluminum. Its properties are brittle and hard. Only sanding products. Mature aluminum exceeds 98% aluminum. It is very soft and can be rolled or pressed into many vessels.

Today we will discuss the characteristics of inferior industrial aluminum profiles:

1. If the chemical composition is unqualified, it will greatly reduce the cost of industrial aluminum profiles containing a large amount of mixed aluminum and waste aluminum, but it will cause the chemical composition of aluminum profiles in the construction industry to be unqualified and seriously endanger the construction safety.

2. Inferior industrial aluminum profiles will greatly reduce the sealing time, reduce the loss of chemical reagents and reduce costs, but the corrosion resistance of the profiles will also be greatly reduced.

3. The thickness of the oxide film is thin. National standards stipulate that the thickness of the oxide film of aluminum profiles in the construction industry should not be less than 10um. If the thickness is not sufficient, the surface of industrial aluminum profiles is susceptible to rust and corrosion. According to estimates from experts, the cost per ton of profile can be reduced by at least 150 yuan for each reduction of the thickness of the oxide film by 1um.

Unqualified industrial aluminum profiles may be deformed by air, rain and sunlight, and may even cause the glass to crack and fall.
