There are many ways to identify industrial aluminum. For those who don’t know the quality of industrial aluminum, if you don’t know how to identify the quality of industrial aluminum profile, you can listen carefully. Next, the aluminum industry and everyone I have shared the methods and methods of industrial aluminum identification to enhance my understanding of industrial aluminum identification. 1. Identification check: Whether the product standard code and production license number are marked on the aluminum profile and packaging. 2. Surface quality: In addition to the surface of the aluminum profile should be clean, no defects such as cracks, peeling, corrosion and bubbles are allowed, and no defects such as corrosion spots, electric burns, black spots, and oxide film shedding are allowed. 3. Oxide film thickness: The oxide film of the aluminum profile is formed during anodization, which has protective and decorative effects and can be detected by an eddy current thickness gauge. 4. Sealing quality: There are many voids on the surface of the aluminum profile after anodization. If it is not sealed or the sealing is not good, the corrosion resistance of the aluminum profile will be reduced. The commonly used methods of sealing quality inspection include acid leaching and guiding Nanofa and phosphobutyric acid method. 5. Corrosion resistance: This index mainly affects the life of aluminum profiles. Corrosion resistance inspections include copper accelerated acetic acid salt spray test and alkali drip test. The above are the ways and methods to identify the quality of industrial aluminum materials shared by the aluminum industry with you. If you want to know more, please pay attention to the official website of aluminum industry!
