How To Prevent Aluminum From Corrosion?
Aluminum is one of the most important elements in nature. As a common metal, it’s often used to make various products. Due to aluminum products have many features include light weight, high strength, ductility, and rust resistance, therefore aluminum products are one of the most popular metal products among various metal products. In our daily life, we can come into contact with aluminum at any time. Such as cars, airplanes, buildings, kitchen appliances, etc.
Aluminum can bring huge profits and improve economic efficiency. But if you are investing in the aluminum products, you should take some steps to prevent aluminum from corroding.
Aluminum Alloy
Pure aluminum is formed into an aluminum alloy by adding other metal elements. Compared with pure aluminum, aluminum alloys are not easily corroded. However, as an important metal material developed in modern times, aluminum alloys, like other metals, also face corrosion problems.
We all know that when aluminum products are exposed to air, a dense oxide film will form on the surface. This film will protect the aluminum product from rusting, but it will not prevent corrosion. In order to solve this problem, we need to do research in this area.
Coating Method
There are many methods to protect aluminum from corrosion, such as storing it in a climate-controlled environment, or adopting a series surface treatment. The common surface treatment is coating technology. We can adopt powder coated and roller coated to painting the surface of aluminum products. In addition, we need to choose anti-corrosion coating like PVDF and PE. Take PVDF coating as an example. As a conventional aluminum alloy surface treatment coating, fluorocarbon coating has good weather resistance, good chemical corrosion resistance and excellent flexibility. Therefore, coated aluminum is the ideal choice for aluminum products manufacturer and buyer.
Summary
Although aluminum can prevent rust, it will inevitably be corroded by the influence of the natural environment. To protect aluminum from corrosion, we can place it in a climate-controlled environment or coat it.
