Aluminum nitride (AlN) ceramics offer high thermal conductivity (170-200 W/(m·K)), significantly surpassing common ceramics like alumina (20 W/(m·K)) and even metals like copper and aluminum. This allows efficient heat dissipation, improving reliability and lifespan in high-power applications.

AlN also provides excellent electrical insulation, with a resistivity of 10¹⁴ Ω·cm and a breakdown voltage up to 15 kV/mm, making it ideal for high-voltage and high-frequency environments. Its high mechanical strength (12 GPa hardness, 308 GPa Young’s modulus) ensures resistance to impact and wear.

Additionally, AlN ceramics are chemically stable, corrosion-resistant, and offer electromagnetic shielding, reducing external interference and improving electromagnetic compatibility.
