As living conditions are getting better and better, people’s requirements for home life are getting higher and higher. The quality of aluminum profiles will directly affect the quality of household items, so how to distinguish the quality of aluminum profiles?
1. Look at the color
The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable for purchase. In general, the cross-section color of normal aluminum alloy profiles is silver-white and the texture is uniform. If the color is dark, it can be determined that it is recycled aluminum or waste aluminum forged.
2. Look at the degree of oxidation
Use a smooth hard object to scratch the surface of the aluminum profile, gently wipe the scratch with your hand and observe. If it cannot be wiped off, it means that the material may have quality problems. If it can be wiped off, it means that the thickness of the oxide film on the surface of the profile is qualified.
3. Look at the toughness
The strength of the profile is not the harder the better. Aluminum has a certain toughness and is not a hard material. It can be forged into different shapes by using this characteristic. Therefore, you need to identify the brand and observe carefully when purchasing.
