How to distinguish the material of aluminum profile?

1. Look at the degree of oxidation: When purchasing, you can lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off. Of course, this should not be done directly on the sample window, the owner can do it at the material vendor displayed by the business.

2. Look at the chromaticity: the color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase. Generally, the color of the section of normal aluminum alloy profile is silvery white and the texture is uniform. If the color is dark, it can be concluded that it is recycled aluminum or scrap aluminum forging.

3. Look at the flatness: check the surface of the aluminum alloy profile, there should be no depression or bulging. The aluminum profile processed by the regular manufacturer has a smooth and bright surface. If it is a small workshop, due to the machine or raw materials, the surface of the profile will appear slightly concave and convex. The balcony window synthesized by such aluminum profile is easily oxidized and deformed in the later stage.

4. Look at the strength: When purchasing, you can bend the profile moderately with your hands. If you bend the profile without any effort, it can be determined that the strength of the aluminum profile is not up to standard, and the strength of the profile is not as hard as possible. Aluminum has a certain degree of toughness. For non-hard materials, this feature can be used to forge different shapes, so the owner needs to look for the brand and carefully observe when purchasing.

5. Look at the gloss: avoid the purchase of aluminum alloy doors and windows that have open bubbles and slag on the surface, as well as cracks, burrs, peeling and other obvious defects.

If there are the above phenomena, it can be concluded that secondary processing and forming of recycled aluminum or scrap aluminum. Such materials are prone to cracking and oxidation due to uneven texture and messy alloy ratio.
