Aluminum nitride insulating ceramics are a type of engineering ceramic that combines excellent electrical insulation with superior thermal conductivity.
Unlike alumina ceramics, aluminum nitride offers not only outstanding insulation properties but also exceptionally high thermal conductivity (reaching 200 W/m·K at 25°C). Additionally, its coefficient of thermal expansion closely matches that of silicon, making it ideal for a wide range of electronic applications.
Key applications for aluminum nitride insulating ceramics include power electronics, semiconductor equipment, RF devices, LED packaging, and electric vehicles.
GORGEOUS CERAMICS (GGS) offers custom manufacturing of aluminum nitride insulating ceramic components in various shapes and specifications—including precision-machined parts such as plates, substrates, spacers, sleeves, and rings. Leveraging our extensive expertise in forming and precision machining, we provide customers with diverse solutions for electrical insulation and thermal management.
