Anodized aluminum disc circle

Anodized Aluminum Disc Circle Overview

Anodized Aluminum Disc Circle is a protective measure for aluminum discs. The aluminum wafer is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, 등.) as the anode, and under specific conditions and applied current, electrolysis is performed to form aluminum circle coating–aluminum oxide thin layer on its surface, So as to achieve the effect of anti-corrosion and anti-oxidation.

Effect Of Anodizing On Circle Disc Aluminum

Generally, the thickness of the anodized protective film of the aluminum wafer is 5-20 microns, and the harder anodized film can reach 60-200 microns. The anodizing treatment increases the corrosion resistance of the aluminum wafer, and at the same time can improve the hardness and wear resistance of the aluminum wafer; the melting point of the hard-anodized film is as high as 2320K, which has better heat resistance than before the anodization. The promotion.

Aluminum Circle Round Features

(1) Good processing performance: The anodized aluminum wafer has a good decorative feeling, moderate hardness, and continuous high-speed stamping. It has good plasticity and is convenient to be directly processed into products without complicated surface treatment, which can greatly shorten the product production cycle and reduce product production costs.
(2) Good corrosion resistance: Alumina film (3μm) with a standard thickness after anodization can be used indoors without discoloration, corrosion, 산화, and rust for a long time. The thickened aluminum oxide film (10μm) anodized aluminum sheet can be used outdoors and can be exposed to sunlight for a long time without fading.
(3) Strong metal texture: the aluminum discs after anodizing treatment have high hardness, which can reach the gem level and have good scratch resistance. Even if the surface is not covered by paint, the metal color of the aluminum plate can be well preserved, highlighting the modern metallic feel, and increasing the texture of the product in appearance.
(4) High fire resistance: pure metal aluminum products without any chemical substances on the surface, even if it does not burn at a high temperature of 600 degrees, it will not produce toxic and harmful gases, which fully meets the requirements of fire protection and environmental protection.
(5) Strong stain resistance: no fingerprints and stains left on the touch, easy to clean, and no corrosion spots.
(6) Excellent insulation, withstand breakdown voltage up to 2000V

Aluminum Circle Disc Plate Application Scenarios：

Because of the excellent chemical and physical properties of the anodized wafer, the high-quality aluminum circle can be widely used in all aspects of life. It’s suitable for kitchen supplies, such as cooking pots, 기구, 조리기구, caution traffic sign, pan, 등.
