Aluminum profiles are widely used; aluminum profile products can be seen everywhere. Shenghai Aluminum listed some methods to choose aluminum profiles as an aluminum profile manufacturer.
- Profile oxide film:
For qualified aluminum alloys, the thickness of the oxide film should reach 10 microns. If you don’t know how to measure, you can lightly scratch the surface of the profile when purchasing to see if the oxide film on the surface can be wiped off. If it is not easy to wipe off, then the quality of this aluminum alloy window is qualified. - Chromaticity of the material:
The color of the same aluminum profile should be relatively consistent. If the color difference is obvious, it is not suitable for purchase. If the surface of the aluminum profile is dark, it should be recycled aluminum or scrap aluminum forged. - Strength:
Generally, when purchasing profiles, you can moderately bend the profiles with your hands. If you can bend the profiles without effort, then it can be determined that the strength of the aluminum profiles is not up to standard. But it does not mean that the harder the aluminum profile is, the better it is. Aluminum itself has a certain degree of flexibility. It is not a hard material, so you should choose it according to your own needs. - Gloss and flatness, if there are cracks, burrs, peeling, etc., do not choose apparent defects. Generally, this profile is also secondary processed by recycled aluminum and waste aluminum, and cracking and oxidation will easily occur in the later stage.
- Thickness:
Generally speaking, the commonly used standard profiles will have a corresponding thickness. If the thickness does not meet the standard, we should consider whether it is a quality problem. - Processing:
Good aluminum alloys are finely processed and have good sealing performance. In contrast, poor-quality aluminum alloys cut corners and have poor sealing performance.
Aluminum has been widely used in various fields such as aerospace, navigation, aviation, automobiles, transportation, bridges, construction, electronics, energy and power, metallurgy and chemical industry, agricultural drainage and irrigation, machinery manufacturing, packaging and anticorrosion, electrical appliances, furniture, and daily use. Applications.
Shenghai Aluminum is mainly made of 6 series 6061 and 6063 aluminum alloys. 6061 and 6063 aluminum alloys are commonly used high-strength aluminum alloys, and the main components include aluminum, magnesium, silicon and copper. It has excellent corrosion resistance, machinability, weldability and mechanical properties. It is widely used in aerospace, automobiles, bicycles, ships, construction, electronic equipment and other fields. If you need aluminum profiles, you can contact our professional sales team.
