The main material of aluminum fence is aluminum, and the reason why the aluminum fence is powder spraying is mainly due to the nature of aluminum.Aluminum is a light metal with bright silver and white luster. Its corrosion resistance is characterized by its characteristics:
First, the higher the purity, the better corrosion resistance, mainly because pure aluminum is in the air with oxygen, producing a very thin and dense natural oxide film on the aluminum surface, which is faster and thicker than other metal oxide films, and thus prevents further corrosion of the harmful gases and water in the air, and has played a protective role.
Two, the mechanical strength is high, but the corrosion resistance is low. Although the corrosion resistance of pure aluminum is good, but the mechanical strength is poor, this restricts the application of aluminum to a certain extent. For this reason, a proper amount of magnesium, copper, zinc and other metals have been added to aluminum to make various types, so that the mechanical strength of aluminum is greatly improved and the application range is greatly expanded, but the corrosion resistance is worse than that of pure aluminum, so it is possible. Corrosion caused by oxidation. This requires powder coating to protect aluminum.
The aluminum fence with powder coating has high corrosion resistance, and also has many advantages such as color diversity, surface texture and so on.
