Aluminum Heat Sink Manufacturers & Suppliers
What is Aluminum Heat Sink
An Aluminum Heat Sink is a passive cooling device that transfers heat from electronic components to the environment via aluminum’s high thermal conductivity. Designed with finned structures to maximize surface area for airflow convection, it is widely used in LED lighting, power modules, telecom systems, and consumer electronics for cost-effective thermal management.
1️⃣ Cost-Efficient: 60% cheaper than copper, handling 80% of medium-low power scenarios
2️⃣ Lightweight: 50% lighter than copper (2.7g/cm³ density), ideal for portable devices
3️⃣ Corrosion Resistance: Natural oxide layer protects in -20℃~150℃ environments
4️⃣ Versatile Manufacturing: Extrusion/stamping/CNC with ±0.2mm tolerance
5️⃣ Eco-Friendly: Fully recyclable and compliant with RoHS/WEEE directives
