What causes scratches on aluminum?
By Ruiqifeng New Material ( www.aluminum-artist.com)
First of all, the quality issue.
1. The temperature is too high in the extrusion production process, so that the tensile strength of the metal surface layer decreases, and the profile is easy to produce cracks if it needs to be rubbed frequently in the process of use.
2. The extrusion speed of aluminum profile production is too fast, which leads to the increase of the additional tensile strength of the metal surface layer, resulting in cracks.
3. The improper control of quenching or aging temperature and time, resulting in substandard tensile strength of the aluminum profiles.
Secondly, improper use.
1. The force is not equal during use, and the force at the same place is too large.
2. The wall thickness of aluminum profile is designed too thin and cannot meet the strength requirements for application.
3. Used in corrosive environment, the surface of the profile is without anticorrosive treatment.
Well, the above are some of the causes of scratches on aluminum profile summarized by Ruiqifeng. You should also pay attention to the quality problems when buying aluminum profiles, and then customize aluminum profiles, and design the shape and wall thickness taking into account the force situation of aluminum profiles. And also consider the surface treatment if profiles are used outdoor or in the other harsh environment.
