Brushed gold anodized aluminum sheet is a specially treated aluminum alloy material that combines brushing and anodizing technology, with a unique appearance and excellent performance. Brushed gold anodized aluminum sheet is an aluminum sheet material that first forms the required texture and lines on the surface of the aluminum sheet through the brushing process, and then undergoes anodizing treatment to form a dense aluminum oxide film on the surface of the aluminum sheet, and presents a golden effect.
Technical specifications of brushed gold anodized aluminum sheet:
– Thickness: 0.18–4.0 mm (commonly used 0.3–3.0 mm
– Width: ≤1250 mm (regular size
– Base material brand: A1100, 5052, 6061, etc.
– Color and texture: gold + straight wire/long wire/broken wire, etc.
– Oxide film performance:
Indoor grade: standard film thickness ≥3μm, corrosion resistant, no discoloration.
Outdoor grade: thickened film (10–25μm), strong weather resistance, no discoloration after long-term exposure to ultraviolet rays.
– Physical properties:
Hardness reaches sapphire level (wear-resistant and scratch-resistant);
High fire resistance (non-combustible at 600℃, non-toxic);
Anti-fouling and easy to clean (anti-fingerprint, resistant to washing).
The process of brushed gold anodized aluminum:
– Wire drawing process: Through mechanical or chemical methods, such as sandpaper polishing, wire drawing machine wire drawing, etc., continuous, parallel, deep and shallow lines or textures are formed on the surface of the aluminum sheet, giving the aluminum sheet a unique texture and line sense.
– Anodizing: The aluminum sheet that has been wired is placed in an electrolytic cell and electrolytically treated as an anode. During the electrolysis process, a layer of aluminum sheet with a thickness of usually 5 microns – 20 microns will form on the surface of the aluminum sheet. The dense aluminum oxide film between microns not only improves the hardness, wear resistance and corrosion resistance of the aluminum sheet, but also provides a basis for the presentation of gold.
Features of brushed gold anodized aluminum sheet:
– Unique appearance:
The delicate texture formed by the brushed treatment is combined with the golden anodized film, which gives the aluminum sheet a unique metallic texture and three-dimensional sense, showing both the luster of the metal and the delicate texture effect, enhancing the decorativeness.
– High hardness:
The surface hardness of the aluminum sheet after anodizing treatment is significantly improved, reaching gemstone grade, and the wear resistance is enhanced, which can effectively resist scratches and wear and extend the service life.
– Good corrosion resistance:
The aluminum oxide film can effectively isolate the aluminum sheet from the external corrosive environment, and can resist acids, alkalis, salts and other chemicals. It can maintain stable performance under different environmental conditions and is not easy to rust and corrode.
– High temperature resistance:
The melting point of aluminum oxide film is high, so that the aluminum sheet can still maintain stable performance in high temperature environment, and it is not easy to deform, discolor and other problems.
– Good electrical properties:
It has low volume resistivity and surface resistivity, as well as good thermal conductivity, and can perform excellent performance when used in electrical and electronic fields.
– Low density:
The relative density is small, the weight is light, and it is easy to transport and install, and it also reduces the overall weight burden of buildings or other application scenarios.
– Environmental protection and health:
No harmful substances are used in the production process, which meets environmental protection requirements; it will not cause any impact on human health during use.
Application fields of brushed gold anodized aluminum sheet:
– Exterior wall decoration:
It can be used for curtain walls and decorative panels on the exterior facades of buildings. The gold anodized aluminum sheets are interwoven with light and shadow to create a flowing visual art, which enhances the overall grade and beauty of the building.
– Interior decoration:
It is widely used in ceilings, partitions, furniture panels, art installations, etc. The matte gold texture can enhance the luxury and quality of the space.
– Electronic and electrical field:
It is often used in the shells of electronic products, such as mobile phones, tablet computers, laptops, etc. It not only meets the product’s requirements for fashion and texture, but also provides good wear resistance and corrosion resistance to protect internal electronic components.
– Automobile field:
It can be used for interior and exterior decoration of cars, such as door interior panels, center console decorative strips, wheel hub decoration, etc., to add a sense of luxury and technology to the car.
– Lighting field:
As a reflector and decoration for lighting fixtures, it can effectively reflect light and improve the lighting effect of the lamps. At the same time, its beautiful appearance also adds decorativeness to the lamps.
– Other fields:
It can also be used in signs, logos, bags, jewelry boxes and other fields to highlight the high-end sense of the brand and enhance the added value of the product.
Brushed gold anodized aluminum sheet combines beauty and functionality and is a popular material choice in modern design. Whether in architecture, furniture or home appliances, this aluminum sheet can provide elegant and durable solutions.
