The "four transformations" of new energy vehicles: lightweighting, intelligence, networking, and electrification. 

The weight of pure electric vehicle models has increased by 10%, and the range has improved by approximately 13.5%. The vehicle weight has decreased by 10%, and the 100-kilometer acceleration time has reduced by 5%. For every 50 kilograms reduction in vehicle weight, the 100-kilometer braking distance will decrease by 1.25 meters. Apart from aerodynamic resistance, the running resistance of the vehicle is closely related to its weight. 

Research on new energy lightweight materials: The weight of a pure electric vehicle is reduced by 10 kilograms, which can increase the mileage by 2.5 kilometers. To enhance the speed and range of electric vehicles, in addition to strengthening the battery and drive system, it is closely related to the lightweighting of the vehicle body. The prominent feature of lightweighting of the vehicle body is the selection of materials. Currently, the lightweight materials used in new energy vehicles mainly include high-strength steel, aluminum alloy, magnesium alloy, carbon fiber, etc. 

According to the route prediction in the "Energy Conservation and New Energy Vehicle Technology Roadmap", by 2025, the domestic market space for aluminum parts will reach approximately 336.57 billion yuan. 

Aluminum alloy material - The mainstream lightweight battery housing material 

The density of aluminum alloy is only one third that of steel. Its characteristics include lightness, recyclability and good formability. When aluminum collides, it can absorb a large amount of energy, making it lightweight and enhancing the safety of the vehicle. 

Theoretically, aluminum vehicles are 30% to 40% lighter than steel vehicles. On average, each vehicle using more aluminum can reduce its weight by 300 kilograms. 

Lightweighting and high safety have made aluminum battery casings the mainstream for power battery casings. Aluminum battery casings are thinner than steel ones and have a relatively lighter weight. Additionally, manufacturers of aluminum profiles for new energy vehicles believe that after a battery explosion, the rupture force of the aluminum shell of the lithium battery is also weaker than that of the steel shell, and the damage caused by aluminum shell power batteries is relatively smaller. 

The Characteristics and Forming of Aluminum Profiles for New Energy Vehicles 

Material characteristics: Low density, good heat conductivity, excellent damping reduction performance, and excellent corrosion resistance. 

Processing and shaping: Cold forming, temperature forming, hot forming, semi-solid forming. 

Currently, more than 80% of the mainstream pure electric battery boxes fall into one of these two structures or a variant of them. Therefore, the study of these two structures holds certain significance for the development direction of lightweight aluminum trays. 

We possess the equipment and production capacity required for manufacturing battery trays for new energy vehicles, including extrusion profiles, bending forming, friction stir welding (FSW welding), robot arc welding (CMT welding), and gantry milling machining centers, etc. We can produce various PHEV and EV battery trays. 

The automotive battery tray is lightweight, highly durable, structurally solid, has high dimensional accuracy, an attractive appearance, and is equipped with the functions to meet the IP67 protection standard. It has become a first-tier supplier for many well-known new energy vehicle manufacturers and power battery manufacturers. 

Application of High-performance Aluminum Profiles for New Energy Vehicles in Automotive Modules and Batteries 

The improved alloy M303 (based on 3003 alloy) undergoes extrusion and drawing processing. It is a high-precision, tough, corrosion-resistant large-section thin-walled rectangular tube/pipe, used for the outer shell of high-power lithium batteries. The application of high-performance aluminum profiles in the heat management system's heat sink. 

Flanged pipe: 

The aluminium alloys used for manufacturing flat tubes and harmonica tubes are 1070, 3003 and the specially developed improved alloy S120 (which is beneficial for reducing alloy composition, forming the profiles and subsequent hardware processing, and has better corrosion resistance compared to the ordinary 3003 alloy). 

2. Specialized special special special saw blades ensure that the saw meets the customer's requirements. 

3. Fully automatic ultrasonic cleaning machine, which removes oil stains from the surface of steel and aluminum chips from the interior, meeting the high cleanliness requirements of battery products.
