Five Applications of Aluminum Products

Aluminum is the 13th element on the periodic table and also a transition metal. Aluminum is the most abundant metal element in the Earth's crust, second only to oxygen and silicon, and is the second most widely used metal globally after iron. However, it was not until the 19th century that humans mastered the technology of separating and producing pure aluminum. Almost everyone in the world has used products containing aluminum at some point.
This is largely due to the unique physical properties of aluminum:
Density: 2.7 g/cm at 20 ℃ ³
Brinell hardness: 245 [-] at 20 ℃
Tensile strength: At 20 ℃, the tensile strength is 90mpa
Melting point: 660 ℃
Specific heat capacity: 900 J/(kg · K) at 20 ℃
Resistivity: 2.6 e-8 Ω· m at 20 ° C
The ideal physical properties, such as abundance, heat capacity, and tensile strength, make aluminum widely used in commodities. It can also be infinitely recycled and is part of the world's infrastructure. According to statistics, among the existing 124 industries in China, there are 113 industries related to aluminum. Replacing steel with aluminum, wood with aluminum, copper with aluminum, and plastic with aluminum has gained widespread social consensus. Let's take a look at the five main applications of aluminum:
1. Cable
Aluminum is an ideal material for distribution networks, whether it is overhead transmission lines or local distribution lines, because it has better conductivity and weight ratio than copper, and is also one of the most common materials in electrical applications. At present, all bare overhead conductors in China have used aluminum and aluminum alloys.
In addition, although the conductivity of aluminum is only slightly over half that of copper, its weight is only 30% that of copper, and the weight of aluminum bare wires with similar resistance is only half that of copper. Aluminum is cheaper than copper, which makes it more cost-effective.
2. High rise buildings
Aluminum is easy to process, has strong durability, corrosion resistance, and is more lightweight than steel. One of its earliest applications was in the field of architecture. This is because aluminum has an outstanding weight to strength ratio and is the core value material for high-rise buildings and skyscrapers.
You should know that if a skyscraper uses steel, its own weight will be much greater, which requires a deeper building foundation, which invisibly increases the construction cost.
3. Window frame
Aluminum alloy frames are very durable and cost-effective, making them the preferred choice for homes and offices. It is also very light and can withstand impacts, which is very useful in areas with strong winds and storms.
Using aluminum as window frames usually has lower maintenance costs than wood, is also cheaper, and is more resistant to scratches, cracking, and damage. However, a major drawback of using aluminum frames is that they are not as energy-efficient as wood and cannot provide the same level of insulation effect.
4. Consumer electronics products
Smartphones, tablets, laptops, tablet TVs, computer monitors, and other electronic products are increasingly using aluminum in production. Aluminum combines aesthetics and practicality, appearing both exquisite and reliable. This meets the basic needs of electronic products.
Electronic product manufacturers have recently been using aluminum to replace steel and plastics. It is mainly used for cooling CPUs and graphics processors, and the excellent thermal conductivity of aluminum makes it an ideal choice for materials in this field. Many manufacturers consider using aluminum alloy instead of plastic casings when producing electronic products, because aluminum alloy materials look more high-end, durable, and sturdy than plastic casings. Aluminum is stronger and more reliable than plastic, but lighter than steel. Coupled with its inherent heat absorption and dissipation capabilities, this type of electronic manufacturer prefers it.
5. Household and industrial appliances
Aluminum is used to manufacture precision pipes for refrigerators and air conditioners - of course, it is not just this part that uses aluminum.
Many household washing machines, dryers, dishwashers, and other appliances are also designed with aluminum frames. The outstanding application of aluminum lies in refrigeration and refrigeration equipment, which is characterized by promoting cooling and efficient refrigeration. Without the excellent thermal conductivity of aluminum, modern refrigerators would not be able to achieve such good cooling effects.
Due to its abundant reserves and excellent performance, aluminum is widely used in modern industry and daily life. Whether it is pots and pans, household appliances, infrastructure construction, aerospace, transportation, many industries benefit from it and have gained more and more recognition
