Aluminum Windows Doors:

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

Aluminum Profiles Features:

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.

Product Description:

Oxidation Technology Introduction:

Aluminum or aluminum alloy products are used as anodes in electrolyte solution, and the process of forming aluminum oxide film on the surface of the aluminum and aluminum alloy is called anodic oxidation treatment of aluminum and aluminum alloy. After anodization, the surface of aluminum can produce several microns - hundreds of microns of oxide film. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear resistance and decoration have been obviously improved and improved.

- The aluminum oxide film is a porous membrane. Whether it is coloured or not, it must be closed before being put into use, so as to improve its corrosion resistance and weatherability. There are three kinds of treatment methods, namely, high temperature hydration reaction closed, inorganic salt closure and organic matter closure.

(1) High temperature water sealing.

This method utilizes the hydration reaction of aluminum oxide film and water to turn the amorphous membrane into a hydrated crystalline membrane.

The hydration reaction can be carried out at both normal and high temperatures, but at high temperatures, especially at the boiling point, the hydrated crystalline membrane is a very stable and irreversible crystalline film. Therefore, the most commonly used aluminum oxide film is treated by boiling water or steam treatment.

(2) Sealing of inorganic salts.

Inorganic salt method can improve the fastness of organic coloring dyes, so it is often used in chemical coloring.

(3) Organic sealing method.

This is the soaking, soaking or coating of the aluminum oxide film. Because of the high cost and the increase of the process flow, it is not easy to use, more or more of the two kinds of methods mentioned above, and the first kind of high temperature hydration is the mainstream.
