Product Overview
Description
Aluminum Nitride Ceramic
Aluminum nitride ceramic (AlN) has excellent properties such as high thermal conductivity, high strength, high resistivity, small density, low dielectric constant, non-toxic, and thermal expansion coefficient matching with Si. It is a new type ceramic material with excellent comprehensive performance. Due to its extremely high thermal conductivity, aluminum nitride can meet the heat dissipation requirements of high-power devices such as optical communication, microwave communication, LED, and high-speed rail.
Advantages：
1.Very high thermal conductivity
