How To Distinguish The Quality of Industrial Aluminum Profiles

In the face of the uneven industrial aluminum profile market, many people do not know how to distinguish the quality of aluminum profiles. In fact, it is very simple, generally speaking, aluminum manufacturers will send samples to you for free, when we get the sample, we can identify from the following aspects:

1, look at the accuracy.

The accuracy of aluminum profiles includes straightness, flatness, twisting degree, thickness tolerance, etc., requiring these accuracy to be controlled within a certain range, the smaller the higher the accuracy, and can be used for some high-precision instruments and equipment. Accuracy also represents the processing strength of the manufacturer, generally speaking, straightness, twist degree is less than ±0.5mm, thickness tolerance is less than plus or minus 0.3mm. Ordinary manufacturers can not achieve high precision, and the products produced have no quality assurance.

2, look at the luminosity chroma.

Good aluminum profile is the same color with aluminum ingot extruded profile, section color is silver white, uniform texture, smooth surface, bright; The surface does not lose light for 20 years and does not change color. The surface color of the bad aluminum profile is black, and it is mostly made of recycled aluminum or containing waste aluminum.

3, look at the service life.

Good aluminum profiles have long service time, are not easy to deform and have good corrosion resistance. Bad aluminum profile hardness is not enough, easy deformation, easy oxidation, insufficient thickness, load-bearing can not meet the requirements of use.
