In industrial production, how to choose good industrial aluminium material? Today, Kaixin Aluminum will tell you. When the aluminum profile has the following situations, it is unqualified.
| × | First, extrusion defects. |
In the extrusion process of aluminum profiles, due to the imperfection of mechanical equipment, immaturity of processing technology and Improper operation by operators, cause white spots, impurity, layering, color difference and deformation defects. Them affecting the quality and characteristics of aluminum profiles.
| × | Second, the anodized film thickness is thin. |
The anodized film thickness of industrial aluminum should not be less than 10 microns. If the thickness is not enough, aluminum surface easy to rust and corrode, shorten the service life. In order to save costs, some unqualified aluminum manufacturers, only have 2-4 microns anodized film, and some even do not have anodized film. It is estimated that Each reduction of 1um anodized film thickness, reduce the power consumption of each ton of profile by 150 yuan. So they can make a lot of profit from it, that's why some customers say the price is low.
| × | Third, the chemical composition is unqualified. |
In order to retain customers, some manufacturers added a large number of mixed aluminum and aluminum scrap into aluminum profile. It can greatly reduce the cost. But the chemical composition of industrial aluminum profiles is unqualified, which reduce the service life of aluminum profiles.
| × | Fourth, reduce the profile wall thickness. |
Some manufacturers will manufacture aluminum profiles with insufficient wall thickness. The original thickness was 1.5mm. In order to save cost, only 1.2mm was realized. In this way, the price of aluminum will be much cheaper. But customers don't know they've been cheated.
So in the choice of aluminum manufacturers we should choose the reputable manufacturers.
Kaixin Aluminum always believe that excellent quality is the basis to retain customers.
We promise all the aluminum we product is reach the export standard.
