Product Overview

Our Aluminum Nitride Ceramic Sleeve (AlN Sleeve) is a high-performance technical ceramic component designed for thermal management and electrical insulation applications. With exceptional thermal conductivity (up to 173 W/mK) and a coefficient of thermal expansion closely matching silicon, AlN is the material of choice for power electronics, LED modules, and semiconductor equipment. This ceramic sleeve offers reliable performance in high-temperature and high-voltage environments.

Key Features – Outstanding Thermal & Electrical Performance

- High Thermal Conductivity – Typically 170W/mK, enabling efficient heat dissipation.

- Excellent Electrical Insulation – Volume resistivity > 10¹⁴ Ω·cm, dielectric strength 17-19 kV/mm.

- Thermal Expansion Matched to Silicon – 3.2-3.4× 10⁻⁶/K, reducing thermal stress in assemblies.

- High Temperature Resistance – Maintains properties up to 2000°C.

- Good Mechanical Strength – Flexural strength 466-496 MPa, suitable for structural support .

- Corrosion and Plasma Resistance – Ideal for harsh semiconductor processing environments.
