Advantages of aluminum:

1. Low density. The density of aluminum is about 2.7g/cm3. It is only one-third as dense as iron or copper.

2. high plasticity. Aluminum has good ductility and can be made into various articles by extrusion, stretching and other pressure processing means.

3. corrosion resistance. Aluminum is a highly electronegative metal, under natural conditions or anodic oxidation will form a protective oxide film on the surface, with much better corrosion resistance than steel.

4. easy to strengthen. Pure aluminum is not very strong, but its strength can be increased by anodizing.

5. easy surface treatment. Surface treatment can further improve or change the surface properties of aluminum. The aluminum anodic oxidation process is quite mature, stable operation has been widely used in the process of aluminum products.

6. good electrical conductivity, easy to recycle.

The aluminum plate of the anode is oxidized to form a thin layer of aluminum oxide on the surface, with a thickness of 5-20 microns and a hard anodized film of 60-200 microns. The anodized aluminum plate improves its hardness and wears resistance, up to 250-500 kg / mm2, good heat resistance, the melting point of the hard anodized film is as high as 2320k, excellent insulation, and the breakdown voltage is as high as 2000V, which enhances the corrosion resistance ω= 0.03 NaCl salt spray does not corrode after thousands of hours.

The oxide film has a large number of micropores in the thin layer, which can absorb various lubricants and is suitable for manufacturing engine cylinders or other wear-resistant parts; The membrane has strong microporous adsorption capacity and can be colored into various beautiful colors. Nonferrous metals or their alloys (such as aluminum, magnesium, and their alloys) can be anodized.

Application range of anodized aluminum plate

Anodized aluminum plate is widely used in mechanical parts, aircraft and automobile parts, precision instruments and radio equipment, building decoration, machine shells, lamp lighting, electronic consumer goods, handicrafts, household appliances, interior decoration, signs, and furniture, automobile decoration, and other industries.

Advantages of anodized aluminum plate

• Good processability: the positive grade aluminum oxide plate has strong decorative properties and moderate hardness. It can be easily bent and formed and can be continuously pressed at high speed. It is convenient to directly process products without complex surface treatment, which greatly reduces the product production cycle and reduces the product production cost.

• Good weather resistance: standard thickness oxide film (3 μ m) The anodized aluminum plate can be used indoors for a long time without discoloration, corrosion, oxidation, and rust. Thickened oxide film (10 μ m) The anodized aluminum plate can be used outdoors and can be exposed to the sun for a long time without discoloration.

• Strong metal sense: the anodized aluminum plate has a high surface hardness, up to gem level, good scratch resistance, no paint cover on the surface, retains the metal color of the aluminum plate, highlights the modern metal sense, and improves the product grade and added value.

• High fire resistance: pure metal products, no paint, and any chemical substances on the surface, no combustion at 600 ° C, no toxic gas, meeting the fire protection and environmental protection requirements.

• Strong stain resistance: no fingerprints, no stain marks, easy to clean, no corrosion spots.

• Strong applicability: widely used, suitable for metal aluminum ceiling, curtain wall panel, aluminum plastic panel, fireproof panel, honeycomb aluminum panel, aluminum veneer, electrical panel, cabinet panel, furniture panel, etc.

Process flow of anodized aluminum plate

Upper shelf - degreasing - water washing - alkali corrosion - water washing - neutralization - water washing - Anodizing - water washing - sealing hole - water washing - lower shelf - testing - packaging.

Degreasing, alkali corrosion, neutralization, anodic oxidation, and hole sealing in the process flow are the key to ensuring the quality of oxidation treatment.
