Aluminum alloy refers to an aluminum alloy synthesized by adding a certain amount of other metals to metallic aluminum. It is a widely used light metal material. In addition to the general properties of aluminum, the addition of different metals to aluminum alloys will produce different metallic properties. The density of aluminum alloy is 2.63~2.85q/cm, the strength 0b is 110~650MPa, the specific strength is close to high alloy steel, the specific stiffness exceeds steel, it has good casting performance and plastic processing performance, and the material has good electrical and thermal conductivity. It has good corrosion resistance and weldability and can be used as structural materials. It is widely used in aerospace, transportation, construction, electromechanical, light weight and daily necessities.
1. Classification of aluminum alloys
Different pure aluminum adds different metals and has different metal properties, including ALxCu series (2000 series), ALxMn series (3000 series), ALxSi series (4000 series), ALxMg series (5000 series), ALxMgxSi series (6000 series) ), ALxZnxMg series (7000 series), etc. Among them, 6060 aluminum and 6060 aluminum, aluminum alloys with magnesium and silicon as the main alloy elements and the Mg2Si phase as the strengthening phase, are the most commonly used.
a.6061 aluminum alloy
6061 aluminum alloy heat treatment can strengthen the alloy, has good formability, weldability, machinability, medium strength, and can still maintain good operability after annealing. b.6063 aluminum alloy 6063 aluminum alloy is widely used For the frames of building aluminum doors, windows, and curtain walls, in order to ensure that doors, windows, and walls have high wind pressure resistance, assembly performance, corrosion resistance, and decorative performance, the comprehensive performance requirements for aluminum alloy profiles are much higher than industrial profile standards.
2. Main uses of aluminum alloys
1. Industrial uses, such as equipment hoods, equipment rack fences, non-standard aluminum profile frames, aluminum profile conveyor belts, automated machinery and equipment, assembly line workbenches, medical equipment, medical stretcher bed frames, etc.
2. In terms of building decoration, it includes various doors, windows and curtain walls, such as interior and exterior decoration of buildings, construction formwork, composite doors and windows, composite aluminum panels, etc. Aluminum alloy materials are widely praised in architectural decoration due to their corrosion resistance, appearance, good noise resistance and good reflectivity of light and heat.
3. On home and car equipment, such as tables and chairs, home decorations, bicycle connectors, car exterior frames, etc.
4. In terms of heat sinks, aluminum profile radiators have excellent performance and are a very good material for radiators.
3. Recycling process of scrap aluminum alloys
a. Use a metal shredder to shred aluminum alloy
b. Use a metal crusher to directly crush aluminum alloys
The recycling value of scrap aluminum alloy is high. When recycling, the scrap aluminum must first be classified into primary categories and stacked in categories, such as pure aluminum, aluminum alloy, cast aluminum alloy, and mixed materials. The scrap aluminum mixture must be dismantled to remove scrap iron, plastic, scrap copper, paint and other impurities in the aluminum alloy material, and undergo multiple sorting such as cleaning, crushing, magnetic separation, and I-leave sorting.
