Aluminum LED Heat Sink Die Casting Composition & Structure
Material: High-thermal-conductivity aluminum alloys (e.g., ADC12, A380) with excellent fluidity and durability.
Monobody Design: Integrated one-piece structure combining:
Base Plate: A flat, machined surface for direct attachment to LED modules, ensuring minimal thermal resistance.
Fins/Radiation Structure: Optimized fin arrays (straight, radial, or pin-fin) cast seamlessly to maximize surface area for heat dissipation.
Mounting Features: Pre-cast threads, slots, and bosses for easy installation of LEDs, drivers, and lenses.
Surface Treatment: Options include anodizing (enhancing corrosion resistance and emissivity), powder coating, or chemical passivation.
