Aluminum plate refers to the rectangular plate formed by rolling aluminum ingot, which is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium-thick aluminum plate, and patterned aluminum plate.
In emerging application areas, aluminum consumption must be gradually promoted through various efforts such as the change of concepts, the maturity of technology, and the guidance and support of policies. It is understood that the current focus areas for expanding aluminum applications include: transportation, building structures, and power. 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. The field of transportation
Scope: Expand the application of all-aluminum trailers, aluminum alloy convertible coal carriers, and high-precision aluminum alloy sheets for cars.
Aluminum profiles used in the transportation field can effectively reduce the dead weight, increase the effective load, and extend the service life, which is of great significance to energy conservation and emission reduction, and to improve the economic benefits of the transportation industry and the efficiency of road transportation.
2. Building structure field
Scope: Expand the application of aluminum alloy building template and aluminum alloy enclosure board
(1) Expand the application of aluminum alloy building templates
At present, the application proportion of aluminum alloy formwork in my country is less than 1%. Large-scale construction companies have continuously improved the standardization, industrialization, and factoryization requirements of building construction, and the public's increase in housing quality requirements have greatly promoted the application of aluminum alloy formwork. In recent years, due to the rapid development of the real estate industry, the production scale of my country's construction template industry has maintained a growth rate of about 10-15%.
While the domestic aluminum alloy template consumption continues to grow, domestic companies are also supplying aluminum alloy template and template aluminum profiles to Brazil, India, Venezuela and other countries as well as Hong Kong and Macao, which will also stimulate domestic aluminum consumption.
(2) Expand the application of aluminum alloy enclosure plates
In domestic civil buildings, large-scale infrastructure projects, especially large-span, complex-shaped projects, such as airport terminals, convention and exhibition centers, stadiums, and other public buildings, have widely adopted aluminum alloy panels for their roofs and walls. However, in industrial buildings, the steel structure system and the metal plate enclosure system accounted for about 70% of the total construction, and the application of aluminum alloy is less.
With the increase in demand for construction projects in overall, strategic, and public welfare fields such as agricultural infrastructure construction, affordable housing projects, and rural dilapidated house renovation, the demand for aluminum alloy enclosures will increase significantly.
3. Electricity field
my country's copper resources are scarce, and a large amount of imports are needed. The consumption of copper in the power sector accounts for more than 40% of the total consumption. The use of aluminum resources that have formed a strong industrial base in my country to replace copper resources with insufficient guarantees can reduce my country’s dependence on copper resources to a certain extent. Enhance the ability to guarantee resources.
(1) Promote the application of copper-aluminum composite conductors
Copper-clad aluminum composite conductor is composed of an aluminum core and a copper cladding layer, and uses the "skin effect" of the current to replace the copper in the middle of the conductor with aluminum. By expanding the cross-sectional area of the conductor to compensate for the impact on the conductivity, so as to achieve the same conductivity. Therefore, it has the advantages of copper's excellent electrical conductivity, good corrosion resistance, and aluminum's low cost and light weight. It is a type of high-performance composite conductor.
In addition, a series of steel (stainless steel) aluminum composite, titanium-aluminum composite, aluminum-aluminum composite plates, strips, foils, and strips have been developed in China, which are used in electric power, electronics, communications, heat dissipation, construction and other industries.
4. Other products and fields
(1) Compared with the foreign level, the traditional consumption field with greater application potential
With the transformation of consumption concepts, the improvement of consumption levels, the improvement of food and drug safety management, and the acceleration of the industrialization process, aluminum lunch boxes, aluminum foil paper extraction, aluminum alloy trays, wine seal packaging, aluminum alloy aerosol cans, aluminum storage Market prospects such as fuel tanks are great.
(2) Application fields that have significant social benefits and urgently need to be promoted
Aluminum alloy bridges, aluminum alloy flood walls, etc., although the amount is not large, they have obvious social benefits.
The main materials of my country's flyovers are steel and other non-aluminum alloys, and the completed aluminum flyovers account for less than 2‰. Aluminum alloy flyovers are getting more and more attention and recognition because of their light weight, high strength, beautiful appearance, corrosion resistance, recyclability, and environmental protection. Not only can the flyover be made of aluminum, if the road bridge can gradually increase the proportion of aluminum used, the amount of aluminum used will be much larger than that of the flyover.
Aluminum alloy flood control wall has the characteristics of light weight and simple installation. Calculated at 40 kilograms per meter of aluminum alloy flood control wall, the amount of aluminum used for a 1 km long and 2 meter high flood control wall is about 400 tons.
(3) Emerging products and application areas that need to increase investment in technology
Aluminum-air battery, aluminum alloy for desalination, etc.
Aluminum-air battery: Aluminum-air battery has a high energy density, can achieve zero emission, no pollution, and easy to recycle during use. It can be used as a power battery, signal battery, etc., and has broad application prospects.
Aluminum alloy for seawater desalination: At present, the surface treatment technology of aluminum alloy pipes for seawater desalination is monopolized abroad. The application of "aluminum instead of copper" in the heat transfer tube of my country's seawater desalination device urgently needs to break through the anti-corrosion technology of the heat transfer tube coating. in.
The above summary is about the new field of aluminum plate use. In the traditional application field, aluminum consumption will naturally increase with the development of related industries. The consumption of aluminum in some fields has been widely used and has become a consumption habit. Such as: aluminum alloy doors and windows, high-speed rail trains, cans, pharmaceutical packaging, building exterior wall decorative panels, cigarette foil, automobiles (except automobile body sheet ABS), etc. Therefore, the application of these products will change with the development of related industries.
