Extruded Aluminum Plate Fin Heat Sink-FAQ's
What materials are used for the plate fin heat sink?
We use high-quality aluminum alloys such as 6063-T5 or 6061-T6 for excellent thermal and structural performance.
Can I customize the fin size and spacing?
Yes, all fin parameters including thickness, height, and gap can be tailored to your thermal requirements.
Do you offer black anodized finishing?
Absolutely. Black anodizing is a standard surface option that improves radiation and corrosion resistance.
What’s the maximum length of each extrusion?
Up to 6 meters per piece, cut to your specified length with tight tolerance.
Can you include mounting holes or rails?
Yes, we can integrate assembly features such as screw holes or PCB slots during the extrusion or machining process.
What’s your minimum order quantity?
The typical MOQ is 200kg, depending on the complexity and profile design.
Do you support rapid prototyping or small batch orders?
Yes, we provide flexible production for both prototyping and volume orders.
