As a heat dissipation tool with high heat dissipation efficiency, aluminum radiator has been widely used in industries such as electronics, electrical appliances and lighting. However, different aluminum radiator manufacturers have mastered different technologies and different production standards, and the heat dissipation effects of aluminum radiators are also graded.   So how to choose a good aluminum profile? You can refer to the following:    1. Look at the degree of oxidation: When selecting and purchasing, you can scratch the surface of the contour to see if the oxide film on its surface can be wiped off.  2. Chromaticity: The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase. Under normal circumstances, the section color of ordinary aluminum alloy profiles is silvery white with uniform texture. If the color is dark, you can conclude that it is forged from recycled aluminum or scrap aluminum.   3. Flatness: Check the surface of the aluminum alloy profile, there should be no depressions or protrusions. The surface of the aluminum profile processed by the regular manufacturer is smooth and bright. If it is a small workshop caused by machinery or raw materials, the surface of the profile will appear slightly uneven. The heat sink synthesized from this aluminum alloy profile is prone to oxidation and deformation in the later stage. 4. Strength: When purchasing, you can bend the profile moderately by hand. If you do not bend the profile, you can conclude that the strength of the aluminum profile is unqualified. In addition, the strength of the profile is not as hard as possible. Aluminum has certain toughness and non-rigidity. The material, using this feature, is well forged into different shapes.  Through the above methods, the quality of aluminum profiles can be basically determined. If you want to produce good heat dissipation effect, in addition to the production process, choose an excellent aluminum profile supplier, for example, you can get twice the result with half the effort.
