The share of steel consumption for the automotive industry has been constantly declining in recent years, while the share of light metal alloys such as aluminium and magnesium has been increasing dramatically. Compared with steel for the automotive industry, aluminum alloys have a series of excellent properties such as low density, high specific strength, high specific rigidity, high impact resistance, good elasticity, and a fairly high recycling rate, and therefore have been given more and more attention. In the future, it is possible that all parts and components of cars will be made from aluminum alloys.
High-Speed Rail Industry
With the growing demand of energy conservation and environmental protection around the world, high-speed rail is developing in the direction of light weight and low energy consumption. Aluminum and aluminum alloys, as the optimum material for weight reduction, have excellent performances that cannot be rivaled by other materials. In rail vehicles, aluminum alloys are mainly used as the train-body structure, and aluminum profiles account for about 70% of the overall weight of the aluminum alloy train body.
Solar Energy Industry
Advantages of aluminum solar panel frames in photovoltaic industry: (1) Good resistance to corrosion and oxidation; (2) High strength and firmness; (3) Good tensile strength performance; (4) Good elasticity, rigidity and high metal fatigue strength; (5) Easy transportation and installation. The surface will not been oxidized even if it is scratched and still keep good performance; (6) Easy material selection and multiple choices. Multiple application scenarios; (7) With a lifespan of 30-50 years or even more.
The aluminum alloys used in the Aerospace industry which we called aerospace aluminum alloys have a series of advantages including high specific strength, good processability and formability, low cost and good maintainability, and are widely used in the main structure of aircraft. The new generation of advanced aircraft in the future will need higher design requirements for high flying speed, weight reduction and better stealth. Accordingly, the requirements for the specific strength, specific firmness, damage tolerance performance, manufacturing costs and structural integration of aerospace aluminum alloy will be greatly increased.
2024 aluminum or 2A12 aluminum has high fracture toughness and low fatigue crack expansion rate and is the most commonly used material for aircraft body and underwing skin.
7075 aluminum alloy is the first one to be used among 7xxx aluminum alloys. The strength of 7075-T6 aluminum alloy was the highest among aluminum alloys in the past, but its performance of resistance to stress corrosion and spalling corrosion is not ideal.
7050 aluminum alloy was developed on the basis of the 7075 aluminum alloy, and has better overall performances on strength, resistance to spalling corrosion and stress corrosion.
6061 aluminum alloy is the first one to be used in aerospace industry among 6XXX series aluminum alloys which has good corrosion resistance performance.
With constant upgrades in science and technology and processing techniques, aluminum alloys are being used more and more widely in electronic products. Aluminum alloys are popular in the field of modern electronic products because of their light weight and high strength, high corrosion resistance, shock resistance, sound insulation and other characteristics. With the constant development of material science and processing techniques, aluminum alloys will become more and more widely used. Aluminum alloy heat sink, aluminum alloy battery shell, aluminum shell for tablet computer, aluminum shell for notebook computer, aluminum shell for portable charger, aluminum shell for mobile audio equipment, etc.
Eco-friendly Smoking Rooms
Eco-friendly smoking room can be used in various situations: offices, office buildings, shopping malls, star hotels, stations, hospitals, 4S shops and other public places and homes. It can not only meet the smokers’ demand but also ensure that other people are not disturbed by passive smoking. The eco-friendly smoking room is with automatic induction technology, multimedia playback technology and the function of automatic purification of second-hand smoke with artificial intelligence induction. Eco-friendly smoking room is not only a smoking room, but also a large indoor air purification equipment.
Machinery and Equipment Industry
Aluminum alloys have low density, high strength and high rigidity, good elasticity and good impact resistance. Aluminum alloys are widely used in transportation, aerospace and aviation, electronics and electrical appliances, petrochemical, construction and packaging, mechanical and electrical, textile machinery, petroleum exploring machinery, glove machinery, printing machinery, forklift trucks, medical equipment, sports equipment as well as people's life and many other aspects.
