Aluminum plate refers to rectangular plate rolled and processed with aluminium ingot, which is divided into pure aluminium plate, alloy aluminium plate, thin aluminium plate, medium and thick aluminium plate and pattern aluminium plate.

In the emerging application fields, the consumption of aluminium should be gradually promoted through the transformation of ideas, maturity of technology, guidance and support of policies, etc. It is understood that the current expansion of aluminum applications in the key areas include: transportation, building structure, power field. In addition, it also includes aluminum alloy pallets, aluminum alloy flood control facilities, aluminum alloy bridges, aluminum foil packaging and other products and fields.

1. Transportation

Scope: Expanding the application of all-aluminium trailer, aluminium alloy open-top coal carrier and high-precision aluminium alloy sheet for car.

Aluminum profiles used in transportation field can effectively reduce self-weight, increase payload and prolong service life, which is of great significance to energy saving and emission reduction, improve economic efficiency of transportation industry and highway transportation efficiency.

2. Architectural Structures

Scope: Expanding the application of aluminium alloy building formwork and aluminium alloy enclosure board

(1) Expanding the application of aluminium alloy building formwork

At present, the proportion of aluminium alloy formwork application in our country is less than 1%. The application of aluminium alloy formwork has been greatly promoted by large-scale construction enterprises'increasing requirements for standardization, industrialization and industrialization of construction, and the improvement of housing quality requirements of the public. In recent years, due to the rapid development of the real estate industry, the production scale of China's construction formwork industry has maintained a growth rate of about 10-15%.

At the same time, domestic enterprises are also supplying aluminium alloy templates and profiles to Brazil, India, Venezuela and Hong Kong and Macao, which will also stimulate domestic consumption of aluminium materials.

(2) Expanding the Application of Aluminum Alloy Enclosure Plate

In domestic civil buildings, large-scale infrastructure projects, especially those with large span and complex shape, such as the roof and wall of airport terminal, Convention and Exhibition center, gymnasium and other public buildings, have been widely used. However, in industrial buildings, the proportion of metal sheet enclosure system in steel structure system is about 70% of the total construction, and the application of aluminium alloy is less.

With the increase of construction demand in the fields of agricultural infrastructure construction, affordable housing projects, rural dangerous housing reconstruction and other global, strategic and public welfare areas, the demand for aluminum alloy enclosure panels will be significantly increased.

3. Electricity field

China is short of copper resources and needs a large number of imports. Copper consumption accounts for more than 40% of the total consumption in the field of electricity. Replacing insufficient copper resources with aluminium resources, which have formed a strong industrial base in China, can reduce the dependence of copper resources on the outside world and enhance the ability of resource security to a certain extent.

(1) Promoting the Application of Copper-Aluminum Composite Conductors

Copper-clad aluminium composite conductor is composed of aluminium core and copper cladding layer. The skin effect of current is used to replace copper in the middle part of conductor with aluminium. The same conductivity can be achieved by expanding the cross-sectional area of conductor to compensate for the influence on conductivity. Therefore, copper is a kind of high performance composite conductor, which has the advantages of excellent conductivity, good corrosion resistance, low cost and light weight of aluminium.

In addition, a series of products of steel (stainless steel) aluminium composite, titanium-aluminium composite and aluminium-aluminium composite plates, strips, foils and layouts have been developed in China, which have been applied in power, electronics, communications, heat dissipation, construction and other industries.

4. Other Products and Areas

(1) Traditional Consumption Areas with Greater Application Potential Compared with Foreign Levels

With the change of consumption concept, the improvement of consumption level, the improvement of food and drug safety management and the acceleration of industrialization process, the market prospects of aluminium dining boxes, aluminium foil paper extraction, aluminium alloy pallets, wine-sealed packaging, aluminium alloy aerosol tanks and aluminium fuel tanks are great.

(2) Application areas with significant social benefits that need to be promoted urgently

Aluminum alloy bridges and aluminium alloy flood control walls have obvious social benefits although they are not used much.

The materials of overpasses in China are mainly made of steel and other non-aluminium alloys, while the proportion of completed aluminium alloy overpasses is less than 2. Aluminum alloy overpasses are gaining more and more attention and recognition due to their advantages of light weight, high strength, beautiful appearance, corrosion resistance, recyclability and environmental protection. Not only can overpasses be made of aluminium, but if highway bridges can gradually increase the proportion of aluminium, the amount of aluminium used is much larger than that of overpasses.

Aluminum alloy flood wall has the characteristics of light weight and simple installation. According to the calculation of 40 kilograms of aluminium alloy flood wall per meter, the amount of aluminium used for flood wall with a length of 1 kilometer and a height of 2 meters is about 400 tons.

(3) Emerging products and application areas requiring greater investment in science and technology

Aluminum air battery, aluminium alloy for desalination, etc.

Aluminum air batteries: Aluminum air batteries have high energy density, can achieve zero emission, no pollution, and easy to recycle. They can be used as power batteries, signal batteries and so on. They have broad application prospects.

Aluminum alloy for seawater desalination: At present, the surface treatment technology of aluminium alloy tubes for seawater desalination is monopolized in foreign countries. The application of "replacing copper with aluminium" in heat transfer tubes of seawater desalination units in China urgently needs to break through the anti-corrosion technology of heat transfer tube coatings, and is currently being developed.

The above summary is about the new field of aluminium plate use. In the traditional application field, the consumption of aluminium will increase naturally with the development of related industries. Aluminum consumption in some areas has been widely used and has become a consumption habit. For example: aluminium alloy doors and windows, high-speed rail trains, cans, medicine packaging, decorative panels for building exterior walls
