Aluminum Heat Sink Extrusion

What is an aluminum extruded heat sink?

Aluminum heat sink Extrusion is an efficient heat sink component manufactured by aluminum extrusion technology. Its core function is to reduce the operating temperature of the equipment and extend its service life through heat conduction and heat dissipation.

Aluminum is an ideal material for heat sinks due to its high thermal conductivity (thermal conductivity is about 205 W/m·K), lightweight (density is about 2.7 g/cm³), corrosion resistance and easy processing.
