Generally speaking, the corrosion forms of aluminum products after aluminum profile processing are various.


There is point corrosion formed by pinpoints on the metal, and galvanic corrosion is that when aluminum is in contact with other metals, the aluminum profile will accelerate corrosion in the anode state. Corrosion present in the gaps is accelerated by a factor of ten or more in vain due to differential gas charging of the cells.


Corrosion of pure aluminum in the unprosperous intergranular due to imperfect heat treatment is also a very common problem. The corrosion under the film in the form of filaments and the corrosion development in the form of filamentous insects make aluminum materials lose the luster of the surface layer and become pulverized. , thus reducing the mechanical properties of aluminum profiles.


After the aluminum profile is processed, the oxide layer on the surface of the aluminum product will not fade or fall off, and it is easy to maintain. The super corrosion resistance of the aluminum profile can withstand the erosion of the marine climate for a long time, and it will not change color while meeting the wind pressure requirements. Does not corrode.


The main properties of aluminum profile processing, namely strength, hardness and wear resistance, are in accordance with the national standard GB6063. The advantages are: light weight of only 2.8, no rust, fast design changes, low mold investment, and longitudinal extension of up to 10 meters. The appearance of aluminum profile processing can be divided into bright and matte. The treatment process adopts anodic oxidation treatment, and the surface treatment oxide film reaches a thickness of 0.12m/m. The wall thickness of aluminum profile processing is selected according to the optimization of product design. It is not that the thicker the better in the market, the design should be based on the requirements of the cross-sectional structure. It can be uneven within 0.5~5mm. A layman thinks that the thicker the tougher, it is actually a wrong view.


Aluminum profile processing is widely used in furniture: screen skeleton, various suspension beams, table legs, decorative strips, handles, wiring troughs and covers, chair tubes, etc., can be designed and used in ever-changing ways!


Aluminum profile processing is common such as screens, aluminum doors and windows, etc. It adopts the extrusion molding process, that is, after the raw materials such as aluminum ingots are melted in the furnace, they are extruded through the extruder until they flow out of the mold, and it can also extrude various profiles of different cross-sections.
