Material Advantages: Core Characteristics of 3003-H14 Aluminum Alloy
3003-H14 is a typical rust-resistant aluminum alloy, widely used in the manufacture of new energy battery casings due to its excellent corrosion resistance, good formability, and high strength stability. Compared to traditional 5052 or 1060 aluminum alloys, 3003-H14 is more suitable for applications that balance mechanical strength and weldability.
Material Characteristics and Advantages:
Strong Corrosion Resistance: Contains Mn, effectively resisting oxidation reactions in electrolytes, moisture, and temperature differences;
Lightweight Design: Low density and high strength, contributing to overall weight reduction and increased energy density;
Excellent Formability: Suitable for deep drawing, bending, and multi-stage forming processes, ensuring a stable and crack-free casing structure.
Good Thermal Conductivity: Effectively disperses internal battery heat, improving heat dissipation and safety performance;
Easy Welding: Compatible with various welding methods (TIG/MIG/laser welding), producing smooth welds without porosity.
Manufacturing Advantages: High-Precision Production and Strict Process Control
Automated Stamping and CNC Precision Machining
High-speed stamping and multi-axis CNC machining technology ensure that dimensional accuracy tolerances are controlled within ±0.05mm. The bottom cover, casing, and interface areas are integrally formed, resulting in a high degree of structural flatness and preventing assembly deviations later.
Cleanroom Welding and Surface Treatment
Automated laser welding and argon arc welding processes guarantee airtightness, sealing integrity, and weld strength. The surface undergoes anodizing or anti-fingerprint electrolytic treatment to effectively prevent corrosion and scratches.
Precision Inspection and Sealing Testing
The entire process involves airtightness testing, torque testing, weld X-ray inspection, and surface stress testing to ensure that each Lithium Battery Aluminum Case meets high-level sealing standards before assembly.
Mold and Customization Capabilities
Our own mold center can perform customized production based on customer drawings or 3D files, meeting diverse design requirements such as different sizes, opening positions, and electrical connection interfaces, supporting both small-batch trial production and large-scale mass production.
