In the era of new energy, various industries such as automotive batteries, lightweighting of vehicle bodies, and automotive components have brought an extremely broad market opportunity to China's aluminum industry. What is the use of aluminum sheets used in new energy vehicles? What are the advantages? What alloys are there? 

In which aspects are aluminum plates used for new energy vehicles? 

At present, the application of various aluminum alloys in automobiles is approximately 77% cast aluminum, 10% rolled material, 10% rolled material, and 3% forged material. The aluminum alloy parts of new energy vehicles mainly include the body, wheels, chassis, impact beams, floors, electric batteries, seats, and many other aspects. 

Advantages of Aluminum Sheets for New Energy Vehicles 

Aluminum plates for new energy vehicles are also being increasingly widely used in the automotive manufacturing industry. Due to its low density, light weight, good forming and processing properties, recyclability, energy conservation and environmental friendliness, aluminum plays a significant role in improving the driving performance and safety of vehicles, reducing fuel consumption, lowering emissions, and minimizing environmental pollution. Aluminum alloy is regarded as one of the ideal materials for future automobiles. 

By implementing the new energy vehicle strategy, in recent years, governments at all levels have adopted policies such as vehicle purchase subsidies and priority for registration in order to promote the consumption of new energy vehicles. The demand and development of new energy vehicles will drive the development of various industries such as automotive batteries, lightweighting of vehicle bodies, and automotive components in the new energy era. At the same time, it will bring an unlimited broad market opportunity for China's aluminum industry. 

Aluminum alloy products for new energy vehicles 

Aluminum alloys used in new energy vehicles include 5052 aluminum, 3003 aluminum, 1060 aluminum, 5083 aluminum, 6061 aluminum, etc. The aluminum plates for car wheels are 6061 medium-thick aluminum sheets; the aluminum plates for the battery shells of new energy vehicles are 3003 anti-rust aluminum sheets; the 1060 aluminum used for the soft connections of the battery power supply is also 1060 aluminum; the alloys used in cars are diverse. 

The application of high-performance aluminum profiles in automotive crash-resistant structural components 

Anti-collision frame - High-strength aluminum alloy (6082, 7046, 7T09) 

Bending cracks are closely related to the microstructure of the material. Through element optimization design and process development, materials with a completely longitudinal fiber structure have better bending performance. By enhancing micro-dispersed precipitation, the strength and toughness of the aluminum alloy are maintained, and the corrosion resistance of the material is improved. This material complies with the Volkswagen TL116 material specification - C32 standard and the Mercedes DBL4919 material specification conflict standard. It is particularly suitable for the production of anti-collision frame profiles. 

Energy absorption structural components - High-strength aluminum alloys (6063, 6008, 7003) 

The energy absorption box is a different case. Based on conventional thinking in materials science, it is impossible to determine the energy absorption effect of the materials. It is generally believed that materials with high elongation are less likely to break during compression. Researcher Filto Alum conducted many experiments, showing the moisture compression performance of aluminum alloys. The average pressure pure force (mean crush force) indicates that it is used for tensile strength and linear increase, and is better in tensile properties. It is a material with the same mechanical properties, and the product with a fibrous structure shows better energy absorption effect. Energy absorption framework: Recrystallization inhibition helps to improve the compression decay performance. 

Automotive components: High-performance aluminum materials are used for automotive interior parts, car sunroof rails, car luggage racks, etc. 

In order to ensure product quality, advanced welding technology is required to be adopted to ensure that the products are integrated as a whole. Undoubtedly, the rapid development of new energy vehicles that use more aluminum than ordinary cars will promote the potential of the aluminum industry in the new energy vehicle market. Developing high-performance and applicable aluminum or processed aluminum components will enable enterprises to open up new directions for various application needs of new energy vehicles.
