Brushed black anodized aluminum sheet is a kind of oxidized and brushed aluminum sheet with black and brushed texture effect on the surface. This kind of brushed aluminum sheet usually has excellent corrosion resistance, abrasion resistance and decorative performance, which is suitable for building decoration, home decoration, electronic product shell and other fields. The price of black anodized brushed aluminum sheet varies depending on a variety of factors, including the specifications, thickness, brand, production process, and market supply and demand, etc. It is generally slightly more expensive than ordinary aluminum sheet.
The production process of brushed black anodized aluminum sheet mainly includes aluminum drawing process and anodic oxidation treatment. The main process of the brushed process includes steps such as degreasing, sanding and washing, which work together to create fine filigree marks on the surface of the aluminum sheet, forming a unique brushed texture. Next, the brushed aluminum sheet is anodized. In this step, the brushed aluminum sheet is placed in an electrolytic bath containing a specific electrolyte as the anode, and under specific conditions and an applied current, a thin layer of aluminum oxide is formed on the surface of the brushed aluminum sheet. This oxide film not only improves the hardness and abrasion resistance of the brushed anodized aluminum sheet, but also enhances its corrosion resistance, giving it better durability in harsh environments.
The brushed black anodized aluminum sheet is mainly made of 1000 series, 3000 series, 5000 series and 6000 series aluminum grades, take 5005 aluminum sheet as the example, H14 temper is usually used, and the thickness of 5005 brushed aluminum coil is 0.3-0.8mm, width is less than 1350mm, the thickness of 5005 h14 brushed aluminum sheet is 0.8-2.0mm, width is less than 1520mm. Special specification can also be produced cut to size according to clients’ requirement.
Brushed black anodized aluminum sheet is widely used in various fields because of its unique appearance and excellent performance. For example, it can be used to manufacture reflective panels and decorations for lighting fixtures, reflective materials for solar collectors, indoor architectural decorations, and exterior wall decorations. In addition, due to its good electrical properties and thermal conductivity, brushed black anodized aluminum sheet is also commonly used in electronic product shells, furniture, automobile interior and exterior decoration and other fields.
