Composite Ceramic AlN-BN, Machinable AlN-BN Ceramics

Boron Nitride Composite Ceramic AlN-BN referred to as AlN-BN composite ceramics, refers to a type of composite ceramic product obtained by combining AlN and BN based on the principle of composite performance superposition. Aluminum nitride-boron nitride composite ceramics have excellent thermal conductivity, low dielectric loss, high elastic modulus, and bending strength of aluminum nitride, and good thermal shock resistance and processing performance of boron nitride. It is a type of high-performance composite material.
