1. Industry Overview

Extruded Heat Sinks – The Core of LED Thermal Management

Extruded aluminum heat sinks, manufactured primarily from 6063 aluminum alloy, enable efficient heat dissipation through finned structures that accelerate conduction and convection. Their advantages include:

• Lightweight (density: 2.7 g/cm³)

• High thermal conductivity (201 W/(m·K))

• Flexible, customized design (power range: 1W–500W)

Applications: Streetlights, indoor downlights, tunnel lighting, and industrial high-bay fixtures.
