rail transit

Aluminum train is light in weight, corrosion-resistant and has good running performance. The aluminum plate is mainly used for the outer plate, roof plate, floor, interior decorative plate and other parts of the rail car. At the same time, some small aluminum tubes are also used for ventilation and transmission inside the car body. For the aluminum alloy plate produced by rail transit, it has the advantages of high strength, good extrusion, good weldability, good corrosion resistance, etc., especially suitable for the use of aluminum train body, underframe and frame, which can reduce the weight of the body while ensuring the strength of the body, effectively save energy and reduce operation and maintenance costs. The typical alloys are 5083, 5A06, 6082, 7020, 7N01, etc.

Aerospace

Aluminum alloy plate is an important structural material for aerospace vehicles, mainly used for fuselage skin, wing and stabilizer skin, fuselage partition frame, oil tank and other structures. Through the application of aluminum alloy composite materials, the shell materials on aerospace vehicles can reduce the density by 5% - 7%, the material stiffness by 7%, and the weight by 10%, so as to improve the fuel efficiency. At the same time, because of the corrosion resistance, good fatigue resistance and damage tolerance of aluminum alloy materials, and the extension of inspection interval, the maintenance cost of spacecraft can be reduced.

a ship

Aluminum alloy plate is mainly used in superstructure such as hull structure and compartment in ship and marine engineering. At the same time, small-diameter aluminum alloy pipe is usually used as pipeline, while large-diameter pipe and bar are used as hull structure, mast component, beam column, etc. in order to lighten the hull, some thin-walled sections are sometimes used in hull structure. Aerospace aluminum products have good strength, processing performance and corrosion resistance, which can fully meet the needs of marine applications.

Automobile manufacturing

Aluminum alloy has been used in buses as early as 1910. Up to now, most of the tank cars, semi trailers and truck bodies are aluminum products. And each commercial vehicle uses about 4 tons of aluminum. The application of aluminum alloy in automobile can bring many benefits, such as: more efficient, higher strength weight ratio, which can meet the requirements of complex shape. In today's increasingly severe period of fuel and environmental problems, aluminum alloy plays an important role in promoting vehicle lightweight and improving fuel efficiency, so as to help alleviate energy and environmental problems. Typical alloys are: 5182, 5083, 6016, 6011, 6n12, 6014, 6181a, 6009, 6005A, 6061, 6082, etc.

Industrial mold

The density ratio of aluminum to steel is 1:3, which can save 1 / 2 in quality. Steel aluminum compound die is used. The cost of aluminum alloy die is about 15% lower than that of steel die. The manufacturing time of aluminum die is much shorter than that of steel die, so it takes less time and has obvious advantages. The cutting cost of the aluminum die is 35% lower than that of the steel die. For the aluminum die, the following processes can be used: repair welding (repair and correction welding), surface hardening treatment (anodizing, electroless plating and nickel plating, etc.) the milling time of the steel die is 5-10 times longer than that of the aluminum die, 5 times longer than the drilling time, 4 times longer than the EDM time, 3-4 times longer than the polishing time, and the service life of the cutting tool is longer than that of the steel die Four times longer. Using aluminum steel compound die can greatly shorten the processing time and save the processing cost. Typical alloys: 2024, 5052, 5754

medical apparatus and instruments

It is mainly suitable for the shell of medical equipment. It is light in weight, well sealed and large in size. After repeated debugging, it can effectively save the stamping frequency and realize the full utilization of manpower and cost. Aerospace aluminum industry has good extrusion performance, welding characteristics, excellent electroplating, high corrosion resistance, high toughness, and is not easy to deform after processing, with good surface treatment performance

Electronic appliances

Aluminum alloy has good machinability and conductivity, and it is an excellent heat dissipation material. According to customer needs, it provides all kinds of extruded profiles, which are suitable for large-scale power supply products such as high-power transformer, stabilized voltage power supply, communication power supply, purification power supply, radio and television transmission device, inverter power supply, and also for power electronic products such as automatic control instruments. The use of aluminum radiator elements can meet the requirements of electronic product design, and also improve the service life of power devices. Aluminum alloy plate is also used to manufacture all kinds of electronic panels and electrical cabinets.

Typical alloys are 2024, 5052, 5754, 5056, 6061, 7075, etc.

Architectural decoration

Aluminum alloy has special advantages in modern architectural applications, such as shape design, appearance and molding. In addition, aluminum alloy has another more important advantage: sustainability. Today, 95% of the aluminum products used in construction are recyclable and made into the same quality products. With the rise of "green building" all over the world, green building materials are the product of the development of science and technology, which make up for the shortcomings of traditional building materials, such as polluting the environment and high energy consumption, and have the functions of repairing the environment and purifying the nature, and promote the development of modern construction industry.
