Advantages of anodized aluminum plate

release time:2014-03-01 09:33:00  Views: 401

Anodized aluminum plate is an aluminum plate placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and electrolysis is carried out under specific conditions and an external current. The aluminum plate of the anode is oxidized to form a thin layer of aluminum oxide on the surface, the thickness of which is 5-20 microns, and the hard anodized film can reach 60-200 microns. The anodized aluminum plate has improved its hardness and wear 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 up to 2000V, enhanced corrosion resistance, no corrosion in ω=0.03NaCl salt spray for thousands of hours. There are a large number of micropores in the thin oxide film, which can adsorb various lubricants, which is suitable for manufacturing engine cylinders or other wear-resistant parts; the film has a strong adsorption capacity and can be colored into various beautiful and gorgeous colors. Non-ferrous metals or their alloys (such as aluminum, magnesium and their alloys, etc.) can be anodized.


    Anodized aluminum plates are widely used in mechanical parts, car power amplifier heat dissipation, lighting heat dissipation, home audio heat dissipation, electronic heat dissipation, aircraft and automobile parts, precision instruments and radio equipment, architectural decoration, machine aluminum housing, electronic consumer goods, handicrafts, interior decoration, signs, Furniture and other industries.


The advantages of anodized aluminum plate:


    1. The anodized aluminum plate has good processability: the positive aluminum oxide plate has strong decorative properties, moderate hardness, and can be easily bent and formed. Continuous high-speed stamping is convenient for direct processing into products without complicated surface treatment, which greatly reduces the product. Production cycle and reduce product production costs.


    2. Good weather resistance: the anodized aluminum plate with standard thickness of oxide film (3μm) will not change color, corrode, oxidize and rust for a long time indoors. The anodized aluminum plate with thick oxide film (10μm) can be used outdoors, and it can not change color under long-term exposure to sunlight.


    3. Strong metallic sense of anodized aluminum sheet: the surface hardness of the anodized aluminum sheet is high, reaching gem level, good scratch resistance, no paint covering the surface, retaining the metallic color of the aluminum sheet, highlighting the modern metallic sense, and improving the product grade and added value.


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


    5. The anodized aluminum plate has strong stain resistance: no fingerprints, no stain marks, easy cleaning, and no corrosion spots.


    6. Strong applicability: Anodized aluminum panels have a wide range of uses, suitable for metal aluminum ceilings, curtain wall panels, aluminum-plastic panels, fireproof panels, honeycomb aluminum panels, aluminum veneers, electrical panels, cabinet panels, furniture panels, etc.
