Anodized aluminum plate - product application knowledge
Jan 28, 2019

The anodized aluminum plate is an aluminum substrate placed in a corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and subjected to electrolysis under specific conditions and an applied current.


The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface, and the thickness thereof is 5 to 20 μm, and the hard anodized film is 60 to 200 μm. The anodized aluminum plate improves its hardness and wear resistance up to 250-500 kg/mm 2 , good heat resistance, and the hardness of the hard anodized film is as high as 2320 K. Excellent insulation and breakdown voltage up to 2000V, enhanced corrosion resistance, does not corrode in thousands of hours in the salt fog of ω=0.03NaCl. The oxide film has a large number of micropores in the thin layer, which can adsorb various lubricants, and is suitable for manufacturing engine cylinders or other wear-resistant parts; the membrane microporous adsorption ability can be colored into various beautiful and beautiful colors.


Application areas:


Anodized aluminum sheets are widely used in machinery parts, aircraft parts, precision instruments and radio equipment, architectural decoration, machine casings, lighting, consumer electronics, handicrafts, household appliances, interior decoration, signage, furniture, automotive decoration and other industries.


Features:


1. Good processability: The positive-grade alumina board has strong decoration and moderate hardness. It can be easily bent and formed for continuous high-speed stamping, which is convenient for direct processing into products without complicated surface treatment, which greatly shortens the product production cycle and Reduce product production costs.

2. Good weather resistance: The standard thickness oxide film (3μm) of the anodized aluminum plate is used indoors for a long time without discoloration, corrosion, oxidation and rust. The anodized aluminum plate with a thick oxide film (10 μm) can be used outdoors, and can be discolored without being exposed to the sun for a long time.

3. Strong metal feeling: The surface of the anodized aluminum plate has high hardness, high gem grade, good scratch resistance, no paint coverage on the surface, retaining the metallic color of the aluminum plate, highlighting the modern metallic feeling, improving the grade and added value of the product.

4. High fire resistance: pure metal products, no paint and any chemical substances on the surface, 600 ° high temperature does not burn, does not produce toxic gases, meets fire protection and environmental protection requirements.

5. Strong anti-fouling: no fingerprints, no stains, easy to clean, no corrosion spots.

6. Applicability: Wide application, 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.
