The difference between anodized aluminum sheet and ordinary aluminum sheet

Although the raw materials of anodized aluminum plates and ordinary aluminum plates are aluminum alloys, their manufacturing process, appearance, properties and uses are different. The following are the main differences between these two types of aluminum panels:

Aluminum plate manufacturing processes are different:

Anodized Aluminum Sheets: During the manufacturing process, anodized aluminum sheets are anodized. This is an electrochemical process in which aluminum is immersed in an electrolyte and controlled by an electric current to form a solid oxide layer on the surface of the aluminum. This oxide layer is usually hard and solid and can change its color and surface properties.

Ordinary aluminum plate: Ordinary aluminum plate has not been anodized, it is the untreated raw form of aluminum. It usually has a glossy silver appearance.

The appearance of the aluminum plate is different:

Anodized Aluminum Sheet: Available in a variety of finish options that can be given different colours, textures and gloss levels. Its surface is generally harder, wear-resistant, corrosion-resistant, and can be customized for different decorative effects. Such as black anodized sheet, white anodized sheet.
Ordinary aluminum plate: usually silver in color, the surface is relatively smooth, without special treatment.

Aluminum plate characteristics:

Anodized aluminum plate: It has high hardness and corrosion resistance, and the surface can withstand a certain degree of wear and scratching.

Ordinary aluminum plate: Relatively speaking, it is soft, easy to scratch, and does not have the protection of anodized layer.

Aluminum sheets are used in different ways:

Anodized Aluminum Sheet: Strong, decorative, and corrosion-resistant, it is often used in interior and exterior trim, building materials, furniture, electronics housings, automotive parts, and other applications that require high-quality aluminum.

Ordinary aluminum plate: usually used for general purposes, such as making cans, tableware, kitchen utensils, building structures, etc.
