Top 6 applications of aluminum alloy

Aluminum alloy has long existed in our life, but in recent years, it has become the representative of Gao Fushai through the application of high-tech products. Especially in the competition of mobile phone design in recent years, Apple, Samsung, Meizu, Xiaomi, Huawei and others have made great efforts in the use of materials and processing technology

Because of its easy processing, good visual effect and rich surface treatment methods, aluminum is the first to be used by various manufacturers. The surface treatment of aluminum profiles is mainly divided into: sandblasting (forming a matt pearl silver surface), polishing (forming a mirror surface), wire drawing (forming a similar satin effect), electroplating (covering a layer of other metals), spraying (covering other non-metallic coatings)

  1. Sand blasting

Sand blasting uses compressed air as the power to form a high-speed jet beam to spray the materials (copper ore, quartz sand, carborundum, iron sand, sea sand) to the surface of the workpiece to be treated at a high speed, so that the appearance or shape of the workpiece surface changes.

Sand blasting has a strong application in engineering and surface technology, such as improving the viscosity of adhesive parts, decontamination, optimizing the surface burrs after machining, and surface matting treatment.

Sand blasting process is more uniform and efficient than manual grinding. This method of stainless steel treatment creates a low-key and durable product.

2. Polishing

The polishing process is mainly divided into mechanical polishing, chemical polishing and electrolytic polishing. Aluminum parts can approach the stainless steel mirror effect after mechanical polishing+electrolytic polishing, giving people a sense of high-end simplicity and fashion in the future

3、Wire drawing

Metal wire drawing is the manufacturing process of repeatedly scraping aluminum plates out of lines with sandpaper. Wire drawing can be divided into straight wire drawing, random wire drawing, spiral wire drawing and thread wire drawing. The metal wire drawing process can clearly show every trace of fine wire, so that the metal matt can have a fine hair luster. The product has a sense of fashion and technology.

4.High gloss cutting

The precision engraving machine is used to reinforce the diamond cutter on the high speed rotating (generally 20000 rpm) precision engraving machine spindle to cut parts, creating local highlights on the product surface. The brightness of the cutting highlights is affected by the speed of the milling drill. The faster the drill speed is, the brighter the cutting highlights will be. On the contrary, the darker the highlights will be and the tool lines will be easily generated. The use of high gloss and high gloss cutting in mobile phones is particularly abundant, such as the iPhone 5. In recent years, some high-end TV metal frames have adopted high gloss milling technology, and the anodizing and wire drawing process has made the TV full of fashion and scientific sharpness.

5.Anodizing

The precision engraving machine is used to reinforce the diamond cutter on the high speed rotating (generally 20000 rpm) precision engraving machine spindle to cut parts, creating local highlights on the product surface. The brightness of the cutting highlights is affected by the speed of the milling drill. The faster the drill speed is, the brighter the cutting highlights will be. On the contrary, the darker the highlights will be and the tool lines will be easily generated. The use of high gloss and high gloss cutting in mobile phones is particularly abundant, such as the iPhone 5. In recent years, some high-end TV metal frames have adopted high gloss milling technology, and the anodizing and wire drawing process has made the TV full of fashion and scientific sharpness.

6.Anodizing

Two color anodizing refers to anodizing a product and giving different colors to specific areas. Double color anodizing has high cost due to its complex process; However, through the contrast between two colors, it can better reflect the high-end and unique appearance of the product
