Aluminum is the most abundant metallic element in the earth's crust after oxygen and silicon. It is the most abundant metallic element in the earth's crust, and the second most used metal in the world after iron. However, it was not until the 19th century that humans mastered the separation and production of pure aluminum. Almost everyone in the world has used aluminum-containing products at some point. Ideal physical characteristics such as abundance, heat capacity, or tensile strength make aluminum widely used in commodities. It can also be recycled endlessly and is part of the world's infrastructure. According to statistics, among the 124 existing industries in my country, 113 are aluminum-related industries. "Use aluminum to replace steel, use aluminum to save wood, use aluminum to save copper, and use aluminum to replace plastic" has gained broad 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 one of the most common materials in electrical applications.At present, aluminum and aluminum alloys are all used for bare overhead conductors in my country.

In addition, although the conductivity of aluminum is only slightly more than half that of copper, its weight is only 30% of copper, while the weight of aluminum bare wires with similar resistance is only half that of copper. Aluminum is also cheaper than copper, which makes it more cost-effective.

2. High-rise buildings

Aluminum is easy to process, durable, corrosion-resistant, and is lighter than steel.One of its earliest applications was in the construction field.This is because aluminum has an outstanding weight-to-strength ratio and is a core value material for high-rise buildings and skyscrapers.

You know, if a skyscraper uses steel, its self-weight will be much greater, which requires a deeper foundation, which in turn increases construction costs.

3. Door and window frame

Aluminum alloy frames are very durable and cost-effective, making them the first choice for homes and offices.It is also light and resistant to impact, which is useful in places with strong winds and strong storms.

Using aluminum for window frames is generally cheaper to maintain and cheaper than wood, and is more resistant to scratches and cracks and damage. However, a major drawback to using aluminum frames is that they do not save energy as energy as wood and do not provide the same water.Flat insulation effect.

4. Consumer electronics products

Aluminum is increasingly used in the production of smartphones, tablets, notebooks, flat-panel TVs, computer monitors and other electronic products.Aluminum is both beautiful and practical, and looks both exquisite and reliable.This meets the basic needs of electronic products.

Electronics manufacturers have recently been using aluminum to replace steel and plastics. It is mainly used to cool CPUs and graphics processors, and aluminum's excellent thermal conductivity makes it an ideal choice for materials in this field. Many manufacturers consider using aluminum alloy instead of the original plastic shell when producing electronic products, because aluminum alloy materials look more high-end, more durable and strong than plastic shells. Aluminum is stronger and more reliable than plastic, but lighter than steel, coupled with its inherent heat and heat dissipation capabilities, making it more popular for such electronics manufacturers.

V.Household and industrial appliances

Aluminum is used to make precision pipes for refrigerators and air conditioners-of course, it's not just this part that uses aluminum.

Many household washers, dryers, dishwashers and other appliances are also designed with aluminum frames. The outstanding use of aluminum lies in refrigeration and freezing appliances, which are 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 results.

Because aluminum is very rich in reserves and has excellent properties, aluminum is widely used in modern industry and life. Whether it is pots and pans, household appliances, infrastructure construction, aerospace, transportation, and many industries benefit from it., and has been increasingly widely recognized.
