Anodizing is an oxidation method for aluminum oxide sheets. It refers to the electrochemical oxidation of metals or alloys. Aluminum and its alloys undergo oxidation on aluminum products (anode) under the action of applied current under the corresponding electrolyte and specific process conditions. the process of forming an oxide film on the surface.

Anodizing in aluminum oxide sheets can not only solve the defects of aluminum surface hardness, wear resistance, etc., but also extend the service life of aluminum and enhance its aesthetics. It has become an indispensable part of aluminum surface treatment and is currently the most widely used and a very successful process.

Different trace elements have different effects on the anodizing effect. Judging from the oxidation effects of various grades, pure aluminum has the best oxidation effect. the 7 series has a high zinc content, and zinc is the chemical component that has the greatest impact on the oxidation effect. Therefore, the oxidation effect of the 7 series is poor.

Generally speaking, the oxidation effect decreases in the following order: 1>5>6>3>2>7. Commonly used alloys include 1060 aluminum sheet, 5052 aluminum sheet, aluminum plate 5083,aluminum plate 6061, 6063 aluminum sheet, etc.

Advantages of aluminium anodised plates:

(1) Good processability: the anodized aluminum plate has strong decorative properties and moderate hardness. It can be easily bent and formed, and can be continuously and high-speed stamped to facilitate 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 (3 μm) 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 by 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 or stains are left, easy to clean, and no corrosion spots.
(6) Strong applicability: wide range of uses, suitable for metal aluminum ceilings, curtain wall aluminum panels, aluminum-plastic panels, fireproof panels, honeycomb aluminum panels, aluminum veneers, electrical panels, cabinet panels, furniture panels, etc.

Application scope:
It is 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.
