Product Introduction
Core Performance and Advantages
1.Exceptional forming capability and structural integrity
Using 3003-H14 aluminum alloy, deep drawing is employed to achieve complex cavities with a depth-to-diameter ratio of ≥2.0 in one piece, eliminating weld seams and improving sealing performance by 60%, preventing electrolyte leakage.
2.Balancing lightweight and high strength
Density of 2.7g/cm³, reducing weight by over 40% compared to steel casing, tensile strength of 110-145MPa at H14 state, passed drop tests from ≥1.5m and compression tests of ≥100kN, achieving a balance between lightweight and safety.
3.Outstanding corrosion resistance and environmental adaptability
Containing 1.2%-1.8% manganese, it forms a natural oxide film, providing a base salt spray resistance of 500 hours. After anodizing, its resistance to electrolyte corrosion improves by three times, suitable for complex operating conditions ranging from -40°C to 85°C.
4.High-efficiency thermal management performance
Thermal conductivity of 155 W/(m·K), combined with thin-walled structures ranging from 0.8 to 3 mm, reduces thermal resistance by 25%, maintaining a temperature difference of ≤5°C across the cell, thereby extending battery life.
5.Electromagnetic shielding performance
The aluminum alloy casing has excellent electromagnetic shielding performance, effectively blocking external electromagnetic interference, protecting the BMS from normal operation, while also reducing the electromagnetic radiation emitted by the battery pack.
