Product Description
This round sunflower aluminum heatsink is formed via one-step aluminum extrusion, featuring radial sunburst fin structure for excellent heat dissipation performance. Made of 6063 aluminum alloy, this circular aluminum heat sink is processed with precision CNC milling, base facing, mounting hole drilling, deburring and ultrasonic cleaning.
We work as a professional heatsink manufacturer offering full custom & OEM service. Customers can adjust dimensions, mounting hole layout, surface treatments based on drawings or samples. The 6063 extruded led heatsink is an ideal thermal solution for COB LED modules and other electronic devices requiring efficient passive cooling.
