Products Description
The Aluminum Nitride Ceramic Cover, made from aluminum nitride (AlN)-a compound with the chemical name aluminum nitride (also known as nitruro de aluminio or nitrure d'aluminium)-is a high-performance aluminum nitride ceramic material. Commonly referred to as AIN ceramic, aluminium nitride ceramic, or aluminiumnitrid keramik, this ALN material is renowned for its excellent thermal conductivity, electrical insulation, and mechanical strength. It is widely used in applications requiring efficient heat dissipation and reliable protection in demanding environments. Key product forms include the aluminum nitride wafer (AlN wafer), aluminum nitride sheet (AlN sheet), aluminum nitride plate (AlN plate), and aluminum nitride substrate (AlN substrate), which serve as foundational components in advanced electronics.

Performance Characteristics
- High thermal conductivity (typically 170-200 W/m·K), making it ideal for AIN high thermal conductivity substrate and ALN heat sink applications.
- Excellent electrical insulation properties and low aluminum nitride electrical conductivity.
- Low thermal expansion coefficient, matching that of silicon, which is critical for aluminum nitride wafers and aluminium nitride substrates.
- High mechanical strength and hardness, suitable for aluminum nitride structural components and ALN structural components.
- Good corrosion resistance and chemical stability.
- Non-toxic and lead-free, meeting environmental requirements.
Products Applications
- Heat sinks and ALN high thermal conductivity substrates for high-power electronic devices (e.g., LEDs, laser diodes, power modules). This includes aluminum nitride ceramic thermal disc and aluminum nitride pads.
- Protective covers, insulators, and components such as aluminum nitride tube and alumina ceramic tube in semiconductor manufacturing equipment.
- Components in aerospace and defense industries, such as radomes and microwave windows.
- Crucibles (AlN crucible, custom aluminum nitride crucible), trays, and aluminum nitride heater components (aluminum nitride ceramic heaters) for metal melting, crystal growth, and high-temperature processes.
- Substrates (aluminum nitride substrates, aln ceramic substrate, AIN polished substrate) for electronic packaging and microwave circuits. Maruwa AlN is a known producer of such high-quality substrates.
- Wear-resistant and corrosion-resistant parts in harsh industrial environments.
- Specialized components like microporous ceramic suction cups and aluminum nitride plates for diverse industrial needs.
