Anodized aluminum plate product application knowledge

Anodized aluminum plate product application knowledge

Anodized aluminum plates place aluminum substrates in corresponding electrolytes (such as sulfuric acid, chromic acid, oxalic acid, etc.) as anodes, and perform electrolysis under specific conditions and applied current. Today Shunjinda will take you to learn about the application knowledge of anodized aluminum plate products:

The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface. Its thickness is 5 to 20 microns, and the hard anodized film can reach 60 to 200 microns. The anodized aluminum plate has improved 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 breakdown voltage resistance up to 2000V, enhanced corrosion resistance, no corrosion after thousands of hours in ω=0.03NaCl salt spray. The thin layer of the oxide film has a large number of micropores, which can absorb various lubricants and is suitable for manufacturing engine cylinders or other wear-resistant parts; the film’s micropores have strong adsorption capacity and can be colored into various beautiful and bright colors.

Application areas:

Anodized aluminum sheet are widely used in mechanical parts, aircraft and automobile parts, precision instruments and radio equipment, architectural decoration, machine casings, lighting, consumer electronics, handicrafts, household appliances, interior decoration, signs, furniture, automobile decoration and other industries.

Features:

• 1. Good processability: The anodized alumina plate has strong decorative properties and moderate hardness. It can be easily bent into shape and subjected to continuous high-speed stamping, which is convenient for direct processing into products. There is no need for complex surface treatment, which greatly shortens the product production cycle and Reduce product production costs.
• 2. Good weather resistance: the anodized aluminum plate with a standard thickness oxide film (3μm) will not discolor, corrode, oxidize or rust for a long time when used indoors. The anodized aluminum plate with thickened oxide film (10μm) can be used outdoors and will not discolor after being exposed to sunlight for a long time.
• 3. Strong metallic feel: The surface hardness of the anodized aluminum plate is high, reaching gem level, and has good scratch resistance. The surface is not covered with paint, retaining the metallic color of the aluminum plate, highlighting the modern metallic feel, and improving product quality and added value.
• 4. High fire resistance: pure metal products, without paint or any chemical substances on the surface, will not burn at 600 degrees high temperature, will not produce toxic gases, and meet fire protection and environmental protection requirements.
• 5. Strong stain resistance: no fingerprints, no stains, easy to clean, no corrosion spots.
• 6. Strong applicability: wide range of uses, suitable for metal aluminum ceilings, curtain wall panels, aluminum-plastic panels, fireproof panels, honeycomb aluminum panels, aluminum veneers, electrical appliance panels, cabinet panels, furniture panels, etc.
