For most applications, aluminum heat sinks are the superior choice due to their lower cost, lighter weight, and adequate thermal conductivity, provided the power density is under 5
A custom heat sink in 2026 typically costs between $2.50 and $45.00 per unit for extruded aluminum, $8.00 to $120.00 for CNC machined copper, and $15.00 to $200.00 for skived or bo
Direct Answer: Which Material Should You Specify?For most forced-convection applications, aluminum heat sinks are the correct engineering choice due to their 50-60% lower cost, 70%
Thermal grease and thermal pads serve the same fundamental purpose—filling microscopic air gaps between a heat source and a heat sink—but they achieve this with dramatically differ
Choosing a heat sink for LED lighting requires matching the thermal resistance of the heatsink to the LED junction temperature limit, typically 85°C to 105°C for high-power chips.
