WHY DO WE CHOOSE ALUMINIUM?
Aluminum’s story
There is a long history of formation along with the formation of the Earth's crust. Aluminium is the most common element in the Earth's crust which accounting for 17% of the Earth's solid mass. Despite being common, mining pure aluminum in the nature seems impossible, and all aluminum on Earth exists as a compound. The reason is that aluminum is oxidized very quickly and aluminum oxide is an extremely durable compound, this aluminum oxide layer becomes an aluminum protective film which making aluminum rustproof.

Aluminum’s application in life
Note for use
AGENTS ACCELERATE THE CORROSION PROCESS, OXIDATION OF ALUMINUM AND DAMAGE:
- Aluminium is directly contacted with fresh concrete.
- Cleaning aluminum surfaces with a highly acidic detergent.
- Aluminum antioxidant layer is scratched due to being cleaned by hard and sharp tools.
- Accessories, rusty screws are damaged after a long period of use.
PREVENTION
- Avoiding contacting directly aluminium with fresh concrete, you should install aluminium doors on dry concrete, if you need to install with fresh concrete, wrapping 1 layer of aluminium protection before placing aluminium in fresh concrete.
- Avoiding using sharp and hard cleaning pads to clean aluminum surfaces.
- Using safe detergents, drying the aluminum surface after cleaning to make its color is more durable.
- Checking the accessories and screws after a long time of use, repairing and replacing to ensure their operation and increase their using time.
SOME COMMON ALUMINIUM SURFACE PHENOMENAS
Aluminium has white spots because cleaning chemicals which splashed into the aluminum rod are dried after drying, or due to being dried or the deposition of minerals in the cleaning water.
The phenomenon of yellow spots because chromium coating helps to increase the adhesion of paint color which stucked to the aluminum rod during the process of spraying and coating and drying after drying.
These common surface faults occur during treatment process of cleaning aluminum surface. This is not oxidation, and they do not affect aluminum quality when used, as aluminum characteristics already have a antioxidant film which preventing the oxidation process from continuing to occur.
