Drawing and anodizing are two different surface treatment processes for aluminum sheets. The brushed aluminum’s manufacturing process is to make the aluminum plate forcibly passed through the mold under the action of external force and the lines are drawn out. The main steps include degreasing, sand mill and washing.
The anodized aluminum plate is to place the aluminium plate in the corresponding electrolyte as an anode, and electrolyzed under specific conditions and applied current. The main process of the process is degreasing, etching, neutralization, anodizing, coloring, and sealing.
After the aluminum plate is brushed, regular brushed textures will appear on the surface. In terms of performance, the brushed aluminum plate is the same as the ordinary aluminum plate, which is easy to scratch, not resistant to ultraviolet rays, and not resistant to washing.
However, the surface of the anodized brushed aluminum sheet will form a very good protective film, which can play a very good role in protecting the brushed aluminum plate. This special layer of oxide film cannot be directly oxidized by placing the aluminum plate in the air. This layer of oxide film can endow the anodized brushed aluminum sheet with excellent properties, such as scratch resistance, UV resistance, washing resistance, fingerprint resistance, and no dust absorption. At the same time, it can also be available in a variety of colors.
When selecting a brushed aluminum plate, it is necessary to know whether there is an anodizing process. The anodizing process can greatly improve the performance of the brushed aluminum plate. It is suitable for architectural decoration, household appliances, switch panels, auto parts, lamps and lanterns, electronic hardware and other industries.
The colors of the brushed aluminum sheet are bronze, green, stainless steel, blue, red, silver, gold, copper, black, pink, brass, bronze, and other colors. The popular size is the brushed aluminum sheets 4x8. Drawing can be made into straight lines, chaotic lines, threads, corrugations, swirls and other lines according to decoration needs.
1. Straight grain drawing refers to mechanical friction processing of straight grain on the surface of aluminum plate. It has the double function of removing scratches on the surface of the aluminum plate and decorating the surface of the aluminum plate. There are two types of straight wire drawing: continuous wire and intermittent wire.
2. Random wire drawing is a kind of matte silk pattern with no rules and no obvious texture. It is brushed by a high-speed copper wire to make the aluminum plate move back and forth, left and right, and rub. This processing places high demands on the surface of the aluminum or aluminum alloy plate.
