At the moment when the global manufacturing industry is booming, aluminum coil has attracted much attention in the international market with its excellent performance and diversified applications. As a kind of aluminum based material, through hot rolling, cold rolling, drawing and other multi-channel precision processing made of coil material with a specific width and thickness, the raw material of aluminum coil is mainly pure aluminum or aluminum alloy. Its unique physical and chemical properties make it play an indispensable role in many fields.

The advantages of aluminum coil are first reflected in its light weight and high strength characteristics. The density of aluminum is only about 2.71g/cm³, which is about a third of the density of steel, which makes aluminum coil a significant advantage in applications where weight requirements are strict. For example, in the aerospace field, each gram of weight reduction may have a significant impact on the performance of the aircraft, aluminum rolls are widely used in the manufacture of aircraft wings, fuselage, engine components, etc., effectively reducing the aircraft's own weight, reducing energy consumption, and improving flight efficiency and fuel economy. According to statistics, a modern passenger aircraft using a large number of aluminum coil materials can reduce its weight by about 20%-30% compared with the aircraft made of traditional materials, and fuel consumption can be reduced by 15%-20%. In the field of automobile manufacturing, in order to meet the needs of energy saving and emission reduction and improve driving range, automobile manufacturers are also increasingly using aluminum rolls to manufacture components such as body panels, engine covers, doors and so on. Taking an ordinary family car as an example, if some steel parts are replaced with aluminum coil parts, the weight of the vehicle can be reduced by 100-150 kg, the fuel efficiency can be increased by 10%-15%, and the handling performance and acceleration performance of the vehicle can be improved.

The aluminum coil also has excellent plasticity and workability. It can be easily processed into various shapes and sizes through rolling, stamping, bending, stretching and other processing methods to meet the diverse design and use needs of different industries. In the construction industry, aluminum coil can be processed into building exterior walls, roofs, partition materials, door and window frames, curtain walls, etc. Its rich color and surface treatment effect not only meet the requirements of the building structure, but also enhance the overall aesthetics and artistry of the building. For example, some modern high-rise buildings use curtain walls made of aluminum rolls, which have a unique shape and luster and become a beautiful scenery in the city. In the field of electronic home appliances, aluminum rolls can be made into shells, heat sinks, electronic components and other products. Taking mobile phones as an example, the mobile phone shell made of aluminum rolls is not only thin and fashionable, but also has good heat dissipation performance, which can effectively protect the electronic components inside the mobile phone and extend the service life of the mobile phone.

The corrosion resistance of the aluminum coil is also a major advantage. The surface of aluminum and its alloys is easy to form a dense aluminum oxide protective film, which can prevent oxygen, moisture and other corrosive substances from contacting the aluminum matrix, thus giving the aluminum coil good corrosion resistance. In harsh natural or industrial environments, aluminum coil can maintain stable performance and extend service life. For example, in coastal areas, due to the large amount of salt in the air, the corrosion of metal materials is strong, and the use of aluminum rolls made of building materials, ship parts, etc., can effectively resist the erosion of sea wind and sea water, reduce maintenance costs and replacement frequency. In the chemical industry, aluminum coil is also widely used in the storage and transportation of corrosive liquids and gases in equipment, such as reactors, pipelines, storage tanks, etc., its good corrosion resistance ensures the safe operation of equipment.

Aluminum coil also has good electrical and thermal conductivity. In the field of power transmission, aluminum coil is widely used in the manufacture of wire, cable and other transmission equipment, although the conductivity of aluminum is about 60% of copper, but because of its light weight, low cost, in long-distance transmission and some electrical conductivity requirements are not particularly high occasions, aluminum coil has a great advantage. For example, in the construction of urban power grids, a large number of aluminum core cables are used, which reduces the transmission cost and improves the transmission efficiency. In the field of electronic equipment heat dissipation, the heat sink made of aluminum coil is widely used in computer cpus, graphics cards, servers and other equipment, and its good thermal conductivity is fast enough to dissipate the heat generated by the equipment to ensure the normal operation of the equipment. Taking an ordinary desktop computer as an example, the use of heat sinks made of aluminum rolls can reduce the temperature of the CPU by 10-15 ° C, effectively improving the stability and performance of the computer.

In addition to the above performance advantages, the application field of aluminum coil is also extremely wide. In the field of construction, it is an important material for building exterior walls, roofs, doors and Windows, curtain walls, etc., which can not only reduce the burden of building structures, but also improve the energy saving effect and beauty of buildings. For example, in some large commercial buildings and public buildings, the roof and curtain wall made of aluminum rolls can achieve unique architectural modeling and design effects, but also effectively heat insulation and reduce energy consumption. In the field of automotive manufacturing, aluminum coils are used to manufacture components such as body panels, hoods, doors, wheels, etc., helping to achieve lightweight vehicles, improve vehicle performance and fuel efficiency, while also improving vehicle safety and comfort. In the field of electronics, aluminum coils are often used to make batteries, electrolytic capacitors, heat sinks, electronic component shells and other products, which meet the requirements of lightweight and high-performance electronic equipment. In the field of packaging, aluminum rolls can be made into food packaging, pharmaceutical packaging, cosmetic packaging, cans, etc., and its good corrosion resistance, barrier property and beauty can not only ensure product quality, but also enhance the attractiveness of products. For example, aluminum cans have the advantages of light weight, easy to carry, good sealing, etc., and are widely used in beverage, beer and other industries.

With the continuous development of the global economy and the continuous improvement of material performance requirements in various industries, the market demand for aluminum coils has shown a strong growth trend. Especially in emerging market countries, such as China, India, Brazil, etc., with the booming development of infrastructure construction, automotive industry, electronics industry, etc., the demand for aluminum coils has increased significantly. At the same time, the enhancement of environmental awareness has also made aluminum coil more popular, because the recovery rate of aluminum is high, which can reach more than 90%, and the production process produces fewer pollutants, which meets the requirements of sustainable development. In international trade, the export volume of aluminum coil is increasing year by year. Russia, China, the United States, Canada and other countries are the main aluminum coil production and exporters. With its rich resources and advanced production technology, Russia's aluminum coil occupies an important position in the international market, mainly exported to Europe, the Middle East, Asia and other regions. As the world's largest aluminum producer and consumer, China's aluminum coil production process has reached a high level, the product variety is rich, the quality is reliable, has a strong competitiveness in the international market, the export market covers many countries and regions around the world.

However, aluminum coils also face some challenges in the development process. On the one hand, the price fluctuation of the global aluminum market is large, affected by a variety of factors such as raw material prices, supply and demand, and macroeconomic situation, which brings certain market risks to aluminum coil manufacturers and traders. On the other hand, with the rise of international trade protectionism, some countries and regions have implemented anti-dumping, countervailing and other trade measures on aluminum products, increasing the difficulty and cost of aluminum coil exports. In order to cope with these challenges, aluminum coil manufacturers and traders need to strengthen market research and analysis, reasonable arrangement of production and inventory, improve risk management capabilities; At the same time, it is necessary to actively expand the domestic market, strengthen technological innovation and product upgrading, and improve the added value and competitiveness of products to cope with the adverse impact of international trade frictions.
