Product detail
AlN Ceramic Heat Sink is made from high-purity Aluminum Nitride Ceramic, a material known for its exceptionally high thermal conductivity and stable electrical insulation. Compared with alumina or zirconia ceramics, High Thermal Conductivity AlN offers a significant advantage in applications where heat must be transferred quickly and reliably.
With thermal conductivity up to 170–180 W/m·K, this ceramic heat sink provides an efficient thermal path for high-power electronic modules, laser devices, RF components and compact circuit assemblies. Its thermal expansion coefficient matches closely with semiconductor materials, ensuring better reliability under thermal cycling.
Mascera supports customed AlN ceramic designs according to drawing requirements. Finned blocks, flat plates, precision-machined surfaces and special-shaped structures can all be manufactured to meet different installation spaces and cooling demands.
