Aluminum alloy has low density, but relatively high strength, close to or more than high-quality steel, good plasticity, can be processed into a variety of profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of second only to steel. The following is an introduction to you about what aluminum alloys belong to and what kinds of processing processes are available, welcome to read!
What does aluminum alloy belong to?
Aluminum alloy is a non-ferrous metal structural material.
Aluminum has low density, but high strength, close to or more than high-quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity, corrosion resistance and other properties, widely used in industry, second only to steel. Through heat treatment, some aluminum alloys can obtain better mechanical properties, physical properties and corrosion resistance.
Hard aluminum alloy is AI-Cu-Mg system, usually contains a small amount of Mn, can be heat-treated to strengthen, its characteristic is hardness, but plasticity is poor. Super hard aluminum alloy is Al a Cu-Mg-Zn system, which can be strengthened by heat treatment, and is an aluminum alloy with high strength at room temperature, but with poor corrosion resistance and fast softening at high temperature.
Forged aluminum alloy is mainly Al-Zn-Mg-Si alloy, although there are many kinds of elements added, the content is small, so it has good thermoplasticity and is suitable for forging, so it is also called forged aluminum alloy.
Aluminum alloy processing
What kinds of aluminum alloy processing processes are there?
1. Sandblasting is also called shot blasting.
The impact of high-speed sand stream is used to clean and roughen the metal surface. Using this method to surface treatment of aluminum parts
, can make the surface of the workpiece has a certain degree of cleanliness and different roughness, thus improving the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increasing the bond strength of the coating and coating, extending the durability of the coating film, but also conducive to the leveling and decoration of the coating. This aluminum processing process we often see in various products of Apple, and is increasingly used in existing TV housings or frames.
Using mechanical, chemical or electrochemical methods to reduce the surface roughness of automotive aluminum parts
, to get a bright, flat surface processing methods. Grinding process is divided into: mechanical polishing, chemical polishing, electrolytic polishing. Car aluminum parts by mechanical polishing + electrolytic polishing can be close to stainless steel mirror effect, giving people a high-grade simple, fashionable, avant-garde feeling (of course, easy to leave handprints to take care of).
3. Wire drawing.
Metal brushing is the manufacturing process with sandpaper will repeatedly scrape the lines of aluminum plate. Straight lines, miscellaneous lines, spin lines, silk lines and several other different ways of drawing can be divided. Jin Gong Weixin, the content is good and worthy of attention. Metal brushing process, can clearly reveal every filament, thus making the metal matte flooded with fine silk luster, the product both fashion and technology.
4. High-gloss cutting.
The diamond cutter is reinforced with a finishing machine to cut the parts on the spindle of the finishing machine which rotates at high speed (generally 20,000 rpm), so that the product surface produces a local high-gloss area. Drill speed has a great impact on cutting high light, the higher the speed of the drill the brighter, and vice versa, the darker, easy to produce knife pattern.
5. Anodic oxidation.
Anodic oxidation is the process of electrochemical oxidation of metals or alloys to form a layer of oxide film on the surface of aluminum products (anode) with certain process conditions under the corresponding electrolyte and specific process conditions. The anodic oxidation method can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and improve its aesthetics, which has become an essential part of aluminum surface treatment, and is also a more widely used and successful process at present.
