SORT:

In the aluminum alloy grade is representative, the following is according to the 7075T651 aluminum plate grade as an example.The first 7 indicates aluminum and aluminum alloy groups - aluminum zinc magnesium series alloys. Aluminum and aluminum alloy groups are divided into nine categories. Among them, aluminum and aluminum alloys of 1, 3, 5, 6 and 7 series are mainly used, and other series are less likely to be used in actual use.

Class 1: Series 1: Industrial pure aluminum

Class 2: Series 2: Aluminum-copper series alloy

Class 3: Series 3: Aluminum-manganese series alloy

Class 4: Series 4: Aluminum-silicon series alloy

Class 5: Series 5: Aluminum-magnesium series alloy

Class 6: Series 6: Aluminum-magnesium Silicon series alloy

Class 7: Series 7: Aluminumzinc magnesium copper series alloy

Class 8: Series 8: Other alloys

Class 9: Series 9: Spare alloys


Specification calculation:

Aluminum sheet material. Panzhu can achieve the widest 600mm of the bar is also more).

Aluminum rod, diameter :3500mm aluminum tube, thickness :2500mm below: aluminum tube, aluminum plate, aluminum rod Panzhu theory calculation formula. (Note: there is an error with the actual weight, the size unit is mm) aluminum plate weight (kg)=0.0000028× thickness × width × length aluminum tube weight (kg)=0.00879× wall thickness ×(outer diameter - wall thickness)× length aluminum rod weight calculation formula (kg)= diameter × diameter × length ×0.0000022

Terminology:

Wire-drawn aluminum plate: The manufacturing process of repeatedly scraping the aluminum

plate out of the line with sandpaper, the main process is divided into three parts: deester, sand mill, water washing.

In the aluminum sheet wire drawing process, the special skin film technology after anodizing can generate a skin film layer containing the metal composition on the surface of the aluminum sheet, which clearly shows each fine wire trace, so that the fine hair luster in the metal matte.

Aluminum oxide plate: The aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and is electrolyzed under specific conditions and impressed current. The anodic aluminum plate is oxidized, and a thin layer of alumina is formed on the surface, with a thickness of 5 to 20 microns, and the hard anodic oxide film can reach 60 to 200 microns.

PS aluminum plate (advertising aluminum plate, also known as printed zinc plate, newspaper plate): that is, the aluminum plate with a printed pattern thickness of 025 or 03 materials on the back.

Mirror aluminum plate: refers to the aluminum plate treated by rolling, grinding and other methods to make the surface of the plate show a mirror effect.

Embossed aluminum plate can also be called aluminum embossed plate: It is an aluminum product that forms various patterns on the surface after calendering processing on the basis of aluminum plate, which is widely used, mainly in packaging, construction, curtain wall and so on.


Chemical composition and properties:

Aluminum Al: surplus; Silicon Si :0.25; Copper Cu :0.10; Magnesium Mg:2.2~2.8; Zinc Zn:0.10; Manganese Mn:0.10; Chromium Cr:0.15~0.35; Iron: 0.4 0.

Tensile strength (σb): 170~305MPa

Yield strength σ0.2 (MPa)≥65

Elastic modulus (E): 69.3~70.7Gpa

Annealing temperature :345℃.


Care and maintenance:

The specific cleaning steps of aluminum plate are as follows:

1, rinse the surface of the plate with a lot of water;

2. Gently wipe the surface of the test board with a soft cloth soaked with detergent diluted with water;

3, then wash the board with a lot of water, wash away the dirt;

4, check the surface of the board, for the place that is not cleaned with detergent;

5. Rinse the board with clean water until the detergent is washed away.

Note: Do not clean the hot surface (temperature over 40 °C), because the moisture volatilization is harmful to the surface paint!

In particular, please choose the appropriate detergent, a basic principle is: be sure to choose neutral detergent! Do not use strong alkaline detergents such as potassium hydroxide, sodium hydroxide or sodium carbonate, strong acid detergents, abrasive detergents and paint dissolving detergents.
