[Aluminum] Aluminum alloy material

If the purity of aluminum metal is greater than 99%, the material is pure aluminum (numbered 1000). In order to meet the requirements of strength, processability and corrosion resistance of various products, corresponding metal elements are added to the pure aluminum metal. , so that it can meet the set requirements. (See chart below)

Anodizing : A-Excellent、B-Good、C-Fair、D-Difficulty

Most of the commonly used aluminum alloys in the past decade are 5000 series, 6000 series and 7000 series materials. The 5000 series and 6000 series are widely used in mobile phones, laptops and other workpieces that focus on appearance; while the 7000 series is not only focused on appearance but also Pay attention to the strength of the metal, especially automobiles, motorcycles, bicycles, etc., which require strong support. However, the 7000 series often encounters material problems during anode treatment, which requires the anode treatment factory to pay more attention to processing.

The anodizing properties of series 1000 to 4000 are worse than the materials just mentioned, so they are less favored by various industrial development departments. Although some products have recently used 2000 series materials, they are only suitable for specific products.
