How to choose standard extruded aluminum profiles with high quality

June 07,2021

Aluminum profiles are widely used, and the standards are also different. Our ultimate goal is to choose high-quality aluminum profiles, so master the purchase tips standard extruded aluminum profiles is the top priority for us.

As a heat dissipation tool with high heat dissipation efficiency, aluminum radiators are widely used in industries such as electronics, electrical appliances, and lighting. However, different aluminum profile radiator manufacturers have different technical processes and refer to different production standards. The aluminum profile radiators produced will also have advantages and disadvantages in terms of heat dissipation effects.

How to choose a good aluminum profile?

?Degree of oxidation

When purchasing, you can swipe lightly on the surface of the profile to see if the oxide film on the surface can be wiped off.

?Chroma

The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase. Generally, the section color of normal aluminum alloy profile is silvery white and the texture is uniform. If the color is dark, it can be concluded that it is recycled aluminum or scrap aluminum forging.

?Flatness

Check the surface of the aluminum alloy profile, there should be no depression or bulging. The aluminum profile processed by a regular manufacturer has a smooth and bright surface. If it is a small workshop due to machinery or raw materials,

The surface of the profile will appear slightly concave and convex, and the radiator synthesized by such an aluminum alloy profile is easy to oxidize and deform in the later stage.

?Strength

When purchasing, you can bend the profile moderately by hand. If you bend the profile without any effort, it can be determined that the strength of the aluminum profile is not up to the standard. In addition, the strength of the profile is not as hard as possible. This feature is good for forging into different shapes.

Attention should be paid when purchasing and using aluminum alloy building profile products

Check the product delivery certificate, pay attention to the delivery date, specifications, technical conditions, company name and production license number.
Observe the surface condition of the product carefully. The product should be bright in color and good in luster. The surface should not have obvious scratches, bubbles and other defects.
Be sure to pay attention to the wall thickness of the product, and the product thickness of the door and window materials should not be less than 1.0mm.
Pay attention to the thickness of the surface coating of the product. The film thickness of anodized products is not less than 10μm, the film thickness of electrophoretic paint products is not less than 17μm, and the thickness of the powder spray coating does not exceed the range of 40-120μm. Fluorocarbon paint spraying The product should be above the second coating and not less than 30μm.
Users in coastal areas are better to choose electrophoretic coating profiles, powder spray profiles or fluorocarbon spray profiles with better corrosion resistance.
Do not use brushes and other hard objects as cleaning tools during routine maintenance. Soft cotton yarn and cotton cloth should be selected.
Water, detergent and soap can be used for cleaning, but other organic substances can not be used.
