How to select high-quality aluminum profiles?

As a heat dissipation tool with high heat dissipation efficiency, aluminum radiator is widely used in electronics, electrical appliances, lighting and other industries. However, different manufacturers of Aluminum Radiator have different technology and different production standards, and the produced aluminum radiator has its advantages and disadvantages in heat dissipation effect.

So how to choose a good aluminum profile?

You can refer to the following aspects:

1. Look at the oxidation degree: when purchasing, you can stroke the surface of the profile to see if the oxide film on its surface can be wiped off.

2. 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 for purchase. Generally, the cross-section color of normal aluminum alloy profiles is silvery white with uniform texture. If the color is dark, it can be concluded that it is forged by recycled aluminum or waste aluminum back to the furnace.

3. Look at flatness: check the surface of aluminum alloy profile, and there should be no depression or bulging. The surface of aluminum profiles processed by regular manufacturers is flat and bright. If it is a small workshop, the surface of the profiles will be slightly concave and convex due to machines or raw materials. The radiator synthesized by such aluminum alloy profiles is easy to be oxidized and deformed in the later stage.

4. Look at the strength: when purchasing, you can use your hands to bend the profile moderately. If you bend the profile without effort, you can confirm that the strength of the aluminum profile is not up to standard. In addition, the strength of the profile is not as hard as possible. Aluminum has certain toughness and is not hard material. Only by using this characteristic can it be forged into different shapes. Through the above several methods, we can basically judge the quality of aluminum profiles. In addition to the production technology and technology, choosing a good aluminum profile supplier can achieve twice the result with half the effort.
