Do you know characteristics of industrial aluminum profile frames?

What is the processing method of industrial aluminum profiles?
1. Oxidation processing. The surface of industrial aluminum profiles is treated with silver-white oxidation, which is elegant, beautiful and corrosion-resistant.
2, extrusion molding. Each specification of aluminum profile has a corresponding production mold, put the aluminum material into the mold, and form the aluminum profile you need by extrusion.
3, casting molding. Have you ever seen the ancient craft of blacksmithing? The casting of industrial aluminum profiles is similar to this.
4, smelting out impurities. The higher the purity of the aluminum, the better the performance. Therefore, the impurity is removed by the melting furnace to increase the performance of the aluminum profile.
5. The ingredients increase the hardness of the product. We know that industrial aluminum profiles are a kind of aluminum alloy profiles, including aluminum-magnesium-silicon alloys, aluminum-zinc alloys, and so on. This can increase the hardness and bearing capacity of the aluminum profile.
