3.2 Lightweight & High-Strength Performance

Lightweight and high-strength performance is another key focus, especially for NEVs and wind turbines. Aluminum materials themselves are lightweight (density of 2.7g/cm³), and through CNC precision machining and alloy optimization, New energy CNC aluminum parts can achieve high strength while maintaining light weight, reducing the overall weight of equipment. For NEVs, this directly improves battery life and energy efficiency; for wind turbines, it reduces the load on the tower and improves power generation efficiency. Compared to traditional cast iron parts, aluminum parts can reduce weight by 40% while ensuring structural strength.

3.3 Corrosion Resistance & Thermal Conductivity

Many New energy CNC aluminum parts work in outdoor or harsh environments (e.g., solar panels, wind turbines, outdoor energy storage systems), so corrosion resistance is a key requirement. Through surface treatments such as anodizing and anti-corrosion coating, these parts can resist rain, humidity, and chemical corrosion, extending their service life. At the same time, thermal conductivity is critical for parts like motor housings and heat sinks—aluminum’s excellent thermal conductivity (200–230 W/m·K for common alloys) allows for efficient heat dissipation, preventing equipment overheating and ensuring stable operation.

3.4 Compatibility & Assembly Precision

New energy CNC aluminum parts need to be perfectly compatible with other components (e.g., electronic components, mechanical parts) in the equipment, requiring high assembly precision. The parts must match the installation dimensions of other components seamlessly, avoiding gaps or loose fits that could affect equipment operation. For example, energy storage enclosure parts must be precisely machined to ensure seamless assembly with battery modules and achieve IP67/IP68 sealing to prevent water ingress.
