How is aluminum produced？

extrusion

Extrusion is a means of profile forming. Firstly, the die is designed and manufactured according to the profile product section, and the heated round cast rod is extruded from the die by extruder. The common grade 6063 alloy also uses an air-cooled quenching process and subsequent artificial aging process during extrusion to complete heat treatment strengthening. Different grades of heat treatable strengthening alloys have different heat treatment systems.

Coloring (here we mainly talk about the oxidation process)

Oxidation: the surface corrosion resistance of extruded aluminum alloy profile is not strong, so the surface treatment must be carried out through anodic oxidation to increase the corrosion resistance, wear resistance and appearance beauty of aluminum.

The main processes are:

(1) Surface pretreatment: clean the profile surface by chemical or physical methods to expose the pure matrix, so as to obtain a complete and dense artificial oxide film. Mirror or matte (Matt) surfaces can also be obtained by mechanical means.

(2) Anodizing: for the surface pretreated profile, under certain process conditions, the substrate surface will be anodized to form a dense, porous and strong adsorption Al2O3 film.

(3) Pore sealing: seal the pores of the porous oxide film generated after anodic oxidation, so as to enhance the anti pollution, anti-corrosion and wear resistance of the oxide film. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before sealing the hole, some metal salts are adsorbed and deposited in the film hole, which can make the appearance of the profile show many colors other than the natural color (silver white), such as black, bronze, golden yellow and stainless steel.

Characteristics and properties of aluminum profiles after various surface treatment processes

Frosted fabric aluminum profile: frosted surface aluminum profile avoids the disadvantage that bright aluminum alloy profile will form light interference under certain environment and conditions in architectural decoration. Its surface is as delicate and soft as brocade, which is very favored by the market. However, the existing frosted material must overcome the uneven sand particles on the surface and see the deficiency of mold lines.

Multi tone surface treatment aluminum profiles: the monotonous silver white and tan color can no longer meet the good cooperation between architects and exterior wall decorative tiles and exterior wall latex. The new stainless steel color, champagne color, golden yellow, titanium gold, red series (wine red, jujube red, black, purple) and colored glass can add to the decorative effect. These profiles must be chemically or mechanically polished and then oxidized for good results.

Electrophoretic painted aluminum profiles: electrophoretic painted profiles have soft surface gloss and can resist the erosion of cement and mortar acid rain. 90% of aluminum profiles in Japan have been electrophoretic painted.

Powder electrostatic spraying aluminum profile: powder electrostatic spraying profile is characterized by excellent corrosion resistance, acid, alkali and salt spray resistance, which is much better than oxidation coloring profile.
