Aluminum delivers lightweight strength and precision for EV components—meeting the industry’s demand for range, thermal control, and structural integrity.


1. Why Aluminum is Essential in EV Architecture

As electric vehicles (EVs) grow in popularity, battery systems add considerable weight—driving the need for lighter structural and functional materials. Aluminum helps offset that weight while maintaining mechanical strength, corrosion resistance, and dimensional accuracy. It enables:

- Improved vehicle range
- Thermal control in electronic systems
- Safer, more durable EV platforms


2. Aluminum's Key Properties for EV Use

Aluminum excels in EV applications due to:
- Lightweight Structure → Boosts energy efficiency and acceleration
- Thermal & Electrical Conductivity → Ideal for heat sinks and inverter housings
- Corrosion Resistance → Long-term reliability in varying climates
- Machinability → Enables CNC, forging, die-casting, and complex shaping


3. Beyond Machining – The Real EV Manufacturing Demands

Producing EV aluminum parts is more than just cutting metal. It involves:
- Tight Tolerance: Up to ±0.01 mm
- Grade Selection: 6061, 5052, 7075 depending on load and heat tolerance
- Surface Treatment: Anodizing, chromating, sandblasting for added durability
- Quality Control: CMM measurement, surface roughness tests, and full inspection reporting


4. Typical EV Parts Made from Forged/Machined Aluminum

Common aluminum components in EVs include:
- Heat sinks for power modules or AC systems
- Brackets for PCB and control modules
- Pulleys and balancing parts in drive systems
- Inverter & battery housing
- Structural mounts for solar-enhanced EVs

These parts require both precision and long-term reliability under high vibration and temperature conditions.
