Quality inspection of aluminum profiles mainly include the following aspects,
1. Chemical composition
The chemical composition of aluminum is one of the important factors affecting its performance. Aluminum generally requires the main component to be high-purity aluminum, while containing small amounts of added elements such as copper, manganese, magnesium, silicon, etc., to adjust the structure and properties of aluminum alloys.
2. Mechanical properties
The mechanical properties of aluminum materials include tensile strength, yield strength, elongation, impact toughness, and other indicators, which are related to the load-bearing capacity and durability of aluminum materials in use and are one of the most commonly used indicators.
3. Surface quality
The surface quality of aluminum is an important indicator for evaluating the appearance quality of aluminum, mainly including defects, oxide skin, color, and gloss on the surface of aluminum.
4. Dimensional accuracy
The dimensional accuracy of aluminum is an indicator for evaluating the dimensional deviation of aluminum, including straightness, flatness, angle, curvature, etc.
The above indicators are the main contents of the quality standards for aluminum materials, and they are also key points that need to be paid attention to during the production and use of aluminum materials.
