Extrusion is a means of profile forming. First, according to the section of the profile product, the mold is designed and manufactured, and the heated round casting bar is extruded from the mold by the extruder. For 6063 alloy, an air cooling quenching process and an artificial aging process are used to complete the heat treatment. Different brands of heat treatable strengthening alloys have different heat treatment systems.
Coloring (here we mainly talk about the process of oxidation)
Oxidation: the surface corrosion resistance of extruded aluminum alloy profile is not strong, so anodizing is necessary to improve the corrosion resistance, wear resistance and appearance of aluminum profile.
The main process is as follows
(1) Surface pretreatment: chemical or physical methods are used to clean the profile surface to expose the pure substrate, so as to obtain a complete and dense artificial oxide film. It is also possible to obtain specular or matte (Matt) surfaces by mechanical means.
(2) Anodizing: after surface pretreatment, under certain process conditions, the substrate surface is anodized to form a dense, porous and strong adsorptive alumina film.
(3) Sealing: the pores of the porous oxide film formed after anodization are sealed to enhance the anti pollution, anti-corrosion and wear resistance of the oxide film. The oxide film is colorless and transparent. By making use of the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film hole, which can make the profile appearance show many colors other than its original color (silver white), such as black, bronze, gold and stainless steel.

Thickness
There are 70 series and 90 series of aluminum alloy sliding doors, and 70 series can be used for aluminum alloy sliding doors in residential buildings. Series number refers to the millimeter number of the structural dimension of the door frame thickness. There are four kinds of aluminum alloy sliding windows: 55 series, 60 series, 70 series and 90 series. Series selection should be based on the size of the window opening and the local wind pressure value. Aluminum alloy sliding window used as closed balcony shall not be less than 70 series.
Strength
The tensile strength should be 157 n / mm 2 and the yield strength 108 n / mm 2. When purchasing, the profile can be bent moderately by hand, and it should be restored to its original state after releasing.
Chroma
The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable to purchase.
Planeness
Check the surface of aluminum alloy profile, there should be no depression or bulge.
Gloss
Aluminum alloy doors and windows to avoid the purchase of open surface bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects of the profile.
Oxidation Degree
The thickness of oxide film should be 10 microns. When purchasing, you can draw on the profile surface to see whether the oxide film on the surface can be wiped off.
Specifications
1 the opening size of doors and windows shall comply with the provisions of GB / T 5824 "series of opening size of doors and windows in buildings".
2 dimensions and specifications of common window openings
one thousand and two hundred × 1500mm
one thousand and five hundred × 1500mm
one thousand and eight hundred × 1500mm
Corrosion Resistance
The density of aluminum profile is only 2.7g/cm3, which is about 1/3 of that of steel, copper or brass (7.83g/ cm3, 8.93g/ cm3, respectively). In most environmental conditions, including in air, water (or salt water), petrochemistry and many chemical systems, aluminum can show excellent corrosion resistance.
Conductivity
Aluminum profile is often selected for its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly 1/2 of copper.
Thermal Conductivity
The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial to the manufacture of heat exchanger, evaporator, heating appliance, cooking utensil, cylinder head and radiator of automobile.
Nonferromagnetism
Aluminum profile is non ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles cannot be self ignition, which is important for the application of handling or contacting inflammable and explosive materials.
Processability
The processability of aluminum profile is excellent. In various deformation and casting aluminum alloys, and in the various states after the production of these alloys, the machining characteristics have changed greatly, which requires special machine tools or technologies.
Formability
The allowable deformation is controlled by specific tensile strength, yield strength, ductility and corresponding processing hardening rate.
Recyclability
Aluminum has high recovery, and the characteristics of recycled aluminum are almost the same as that of primary aluminum.
