General characteristics of aluminum:The excellent characteristics of aluminum and its alloys are good appearance, light weight, machinability, good physical and mechanical properties, and corrosion resistance, which are considered economical and practical in many application fields.The density of aluminum is only 2.7 × 103 kg/m3, which is about one-third of the density of steel, copper, or brass. Due to its lightweight material, aluminum is commonly used in the manufacturing of land, sea, and air transportation vehicles such as cars, trains, subways, ships, airplanes, rockets, and spacecraft to reduce their own weight and increase their loading capacity. Aluminum is also used in China.Under most environmental conditions, including air, water (or saltwater), petrochemicals, and many chemical systems, aluminum exhibits excellent corrosion resistance.The surface of aluminum has high reflectivity, and radiation energy, visible light, radiation heat, and electric waves can be effectively reflected by aluminum. However, surfaces that have been anodized or dark anodized can be reflective or absorptive. After polishing, aluminum reflects well over a wide wavelength range, making it suitable for various decorative and reflective purposes.Aluminum typically exhibits excellent electrical conductivity, with a conductivity of about two-thirds that of copper. However, due to its density being only one-third that of copper, aluminum's conductivity is about twice that of copper when compared to aluminum wires of equal mass and length. It is also lower than copper and has lower applications. Therefore, it is often used in the power and electronics industries. Currently, some specific alloys with high electrical resistivity have also been successfully developed, which can be used in high rotor electric motors. Aluminum has a high thermal conductivity, second only to copper. Its thermal conductivity is three times greater than that of iron, approximately 50% to 60% that of copper. Although copper has thermal conductivity, it is much heavier and more expensive to manufacture workpieces of the same size than aluminum. Therefore, manufacturing aluminum radiators is still necessary. Aluminum is beneficial for manufacturing heat exchangers, evaporators, heating appliances, cooking utensils, as well as cylinder heads and radiators for automobiles.Aluminum is non-magnetic, which is an important characteristic for the electrical and electronic industries.Aluminum cannot self ignite, which is crucial for industries involving loading, unloading, or contact with flammable and explosive materials. Aluminum has very low toxicity and is typically used to manufacture containers for food and beverages. In recent years, aluminum foil has been increasingly used in the packaging of cigarettes, drugs, and food, and has become an important material in the packaging industry.The natural surface state of aluminum has a pleasant appearance. It is soft, glossy, and can also be colored or dyed with textured patterns for aesthetic purposes. In modern life, aluminum has been widely used in the construction industry and daily necessities. Aluminum also has good sound absorption properties. Based on this characteristic, some broadcasting rooms, ceilings in modern large buildings, etc. have adopted aluminum.Aluminum has excellent plasticity. Pure aluminum is very soft, not strong, and has good ductility. It can be drawn into fine wires and rolled into foil, and has good machinability. It is widely used in the wire and cable manufacturing industry, wireless industry, and packaging industry. Adding a small amount of aluminum to certain metals can greatly improve their performance. Adding a small amount of magnesium and copper to aluminum can produce tough materials; Another example is bronze aluminum (containing 4% to 15% aluminum) alloy, which has high strength corrosion resistance, hardness similar to low carbon steel, and a metallic luster that is not easily darkened. It is commonly used in jewelry and construction industries, for the manufacturing of machine parts and tools, for pickling equipment and other equipment in contact with dilute sulfuric acid, hydrochloric acid, and hydrofluoric acid. It can be used to make electric welding machine brushes and clamps, heavy-duty gears and worm gears, metal forming molds, machine tool guides, spark free tools, non-magnetic chains, pressure vessels, heat exchangers, compressor blades, ship propellers, and anchors. Adding magnesium to aluminum produces aluminum magnesium alloy, which has much higher hardness than pure magnesium and aluminum, and retains its lightweight characteristics. It is commonly used to manufacture aircraft bodies, rocket bodies, doors and windows, beautify living environments, and manufacture ships; Adding other metal components to aluminum can result in various forms, some of which even exceed the strength of structural steel.Aluminum connections are also easy and can be made using various methods, including fusion welding, resistance welding, hard welding, soft welding, bonding, and mechanical methods such as riveting and bolted connections. Compared to iron, aluminum is less prone to corrosion and extends its service life. Therefore, the recyclability and characteristics of recycled aluminum are almost no different from those of primary aluminum, which makes aluminum a favorite among environmentalists.
