What are the key indicators for purchasing aluminum alloy profiles?

Film thickness: The surface corrosion resistance of extruded aluminum alloy profiles is not strong, and surface treatment is required to increase the corrosion resistance, wear resistance and aesthetics of aluminum;
Wall thickness: The wall thickness of the profile is one of the main factors affecting the strength of the processed parts, and the main profile is the stress-bearing part in the project;
Chemical composition and mechanical properties: The chemical composition and mechanical properties of aluminum alloy profiles of different grades and supply states are different;
Color and color difference: Alloys of different grades and supply states have differences in color and color difference. It is recommended to fully consider the impact of inconsistent color and color difference on the building structure when selecting alloy grades and supply states;
Salt spray corrosion resistance, wear resistance, weather resistance, mortar, etc.: These are important technical parameters of aluminum alloy profiles, which reflect the performance of aluminum alloy profiles and affect their use.
