Aluminum Profiles Surfaces Treatment Types:

1.Sand blasting
The process of cleaning and roughening metal surface by using the impact of high-speed sand flow. The surface treatment of aluminum parts by this method can make the surface of the workpiece obtain certain cleanliness and different roughness, and improve the mechanical properties of the workpiece surface. Therefore, it improves the fatigue resistance of the workpiece, increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating.
2. Polishing
Using mechanical, chemical or electrochemical methods to reduce the surface roughness of the workpiece, so as to obtain a bright and flat surface. Polishing process is mainly divided into: mechanical polishing, chemical polishing and electrolytic polishing. After mechanical polishing + electrolytic polishing, it can approach the stainless steel mirror effect, giving people the feeling of high-grade, simple and fashionable future (of course, it is easy to leave fingerprints, and more care should be taken).
3. Wire drawing
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, rotary wire drawing and thread drawing. The metal wire drawing process can clearly show each fine wire mark, so that the fine hair luster can be reflected in the metal matte. The product has a sense of fashion and science and technology.
4. High gloss cutting
The diamond knife is reinforced on the main shaft of the precision engraving machine with high-speed rotation (generally 20000 RPM) by the precision engraving machine to cut parts, resulting in local bright areas on the product surface. The brightness of cutting highlight is affected by the milling bit speed. The faster the bit speed is, the brighter the cutting highlight is. On the contrary, it is darker and easy to produce knife marks. High gloss cutting is especially used in mobile phones.
5. Anodizing
Anodizing refers to the electrochemical oxidation of metals or alloys. Aluminum and its alloys form an oxide film on aluminum products (anodes) under the action of external current under the corresponding electrolyte and specific process conditions. Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance the beauty. It has become an indispensable part of aluminum surface treatment. It is the most widely used and very successful process at present.
6. Two Color Anodizing
Two Color Anodizing refers to anodizing on a product and giving different colors to specific areas. The cost of two-color anodizing is high because of the complex process; However, through the comparison between two colors, it can better reflect the high-end and unique appearance of the product.

Aluminum Profiles Features:

Corrosion resistance
The density of aluminum profile is only 2.7g/cm3, which is about 1/3 of that of steel, copper or brass (7.83g/ cm3, 8.93g/ cm3, respectively). In most environmental conditions, including in air, water (or salt water), petrochemistry and many chemical systems, aluminum can show excellent corrosion resistance.
conductivity
Aluminum profile is often selected for its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly 1/2 of copper.
Thermal conductivity
The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial to the manufacture of heat exchanger, evaporator, heating appliance, cooking utensil, cylinder head and radiator of automobile.
Nonferromagnetism
Aluminum profile is non ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles cannot be self ignition, which is important for the application of handling or contacting inflammable and explosive materials.
Processability
The processability of aluminum profile is excellent. In various deformation and casting aluminum alloys, and in the various states after the production of these alloys, the machining characteristics have changed greatly, which requires special machine tools or technologies.
Formability
The allowable deformation is controlled by specific tensile strength, yield strength, ductility and corresponding processing hardening rate.
Recyclability
Aluminum has high recovery, and the characteristics of recycled aluminum are almost the same as that of primary aluminum.
