Today, as living conditions are getting better and better, people have higher and higher requirements for home life. The quality of aluminum profiles will directly affect the quality of household products, so how to identify the quality of aluminum profiles?
1. Look at the chroma
The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable to purchase. And generally, 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 concluded that it is recycled aluminum or forged from scrap aluminum.
2. Look at the degree of oxidation
Use a smooth hard object to scratch the surface of the aluminum profile, gently wipe the scratches with your hands 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 as hard as it is. Aluminum has a certain toughness and is not a hard material. This characteristic can be used to forge it into different shapes. Therefore, you need to look for the brand and observe carefully when purchasing.
