Automotive Industry
Industry Challenges and Needs (The Challenge) With the rapid development of new energy vehicles, lightweighting and thermal management have become core issues. Automotive components must achieve maximum weight reduction while ensuring high impact resistance and fatigue strength, and simultaneously meet stringent traceability and supply chain security standards.
Alumag's Solution (Our Solution) We use high-strength alloys such as 6082, 7003, and 7075, combined with precision extrusion and multi-axis CNC machining, to manufacture battery pack housings, anti-collision beams, and motor housings with uniform wall thickness and excellent airtightness. The entire process is managed according to the IATF 16949 system, providing complete PPAP, IMDS, and 8D reports to ensure zero-defect delivery.
Key Applications
Battery Pack Housing – Large cross-section thin-wall extrusion + high-precision CNC milling, dimensional tolerance ±0.1mm
Collision-absorbing Box – Seamless aluminum tube cold drawing + end forming, high-strength 7000 series alloy
Motor Housing – Profile extrusion with heat dissipation fins + airtightness testing
Dashboard Crossbeam Bracket – Complex hollow profile, 40% weight reduction
Thermal Management System Piping – Precision aluminum tube + bending/flaring/punching
Lightweight Subframe – Multi-profile welded assembly, bench fatigue verified
Material & Process
Alloy Grade | Temper | Key Feature | Typical Use |
6061 | T6 | Good corrosion resistance, moderate strength, excellent weldability | Body structural components, brackets |
6082 | T6 | Strength higher than 6061, excellent machinability | Battery casing, crash beams |
7003 | T5/T6 | High strength, weldable, good toughness after natural aging | Bumper energy-absorbing boxes, door crash bars |
7075 | T73/T651 | Ultra-high strength, similar to aerospace grade | Suspension control arms, high-performance racing components |
Case Study
Helping a European Tier 1 Supplier Achieve Battery Tray Lightweighting A well-known German automotive parts company wanted to reduce the weight of its next-generation hybrid battery pack tray by more than 15%, while also reducing costs. Alumag's technical team redesigned the cross-sectional structure, employing the 6082-T6 hollow multi-cavity extrusion process to replace the traditional splicing and welding method, resulting in a 22% weight reduction and passing a 72-hour airtightness test. The project took only 8 weeks from trial molding to mass production delivery, and the customer has already added Alumag to their list of preferred global aluminum suppliers.
