Silver Anodizing profiles for aluminium outside

For the testing standards of the oxidized silver white treatment of aluminum alloy profiles, our factory usually includes the following aspects of testing:

Oxide thickness: The quality of the treatment is assessed by measuring the thickness of the oxide layer. This is usually done with a thickness measuring instrument, such as an electronic thickness gauge.

Color Consistency: Detects whether the color of the oxidized silver-white surface of the aluminum alloy profile is consistent with the expected standard range of color differences. Usually use colorimeter or spectrometer to test.

Corrosion resistance: assess the corrosion resistance of treated aluminum alloy profiles through salt spray test and other methods. Usually set the test conditions and duration according to the relevant standards, and then observe the corrosion of the sample.

Adhesion: Detect the adhesion of the oxide layer coating to the substrate, usually assessed by peeling test.

Porosity test (if there is a sealing treatment): The micro-pores in the oxide layer are examined to ensure the effectiveness of the sealing treatment. This may involve the use of specific test methods or equipment.

These tests are usually based on relevant international standards, industry standards or customer requirements. In practice, it may be necessary to select the appropriate test method and standard to ensure that the product quality meets the requirements.
