FAQ – Aluminum Extruded Radiator

Q1: What is an Aluminum Extruded Radiator?
A: An Aluminum Extruded Radiator is a passive heat dissipation component manufactured by forcing 6063/6061 aluminum alloy billets through specialized molds. It forms high-density fins, complex flow channels, or irregular structures in a single extrusion, providing efficient thermal management for electronics, vehicles, and industrial equipment.

Q2: How does an Aluminum Extrusion Heat Sink differ from traditional radiators?
A: Unlike traditional cast or machined radiators, an Aluminum Extrusion Heat Sink eliminates porosity, increases thermal conductivity, and allows for more complex structures like microchannels and wave-shaped fins. This improves heat transfer efficiency while reducing weight.

Q3: What materials are used?
A: Commonly used materials are 6063 and 6061 aluminum alloys, which contain 0.2–0.6% silicon and 0.45–0.9% magnesium. These alloys offer high thermal conductivity, lightweight properties, and excellent corrosion resistance.

Q4: Can the radiators be customized?
A: Yes. Custom Extruded Aluminum Radiator designs are possible, including variable fin thickness (0.5–2 mm), irregular cavities, and cross-sectional complexity ≤8. Molds can be developed in 15–20 days for small or large batch orders.

Q5: What are the advantages of Extruded Aluminum Cooling Fins?
A: They provide:

• Increased heat dissipation area with lower air resistance

• Higher thermal conductivity than cast aluminum

• Lightweight and strong mechanical properties

• Long-lasting corrosion resistance after anodizing

Q6: Where can Aluminum Extruded Thermal Management Components be applied?
A: Typical applications include:

• New energy vehicles: battery pack liquid cooling plates, motor controllers

• 5G communication: base station RF units, server GPU cooling

• Industrial power: photovoltaic inverters, energy storage systems

Q7: How resistant is the anodized surface?
