Aluminum Nitride

Aluminum Nitride (AlN) is highly valued for its ability to combine exceptional thermal conductivity with excellent electrical insulation, making it a critical material across a wide range of high-performance applications.

Its unique combination of properties – including thermal shock resistance, mechanical strength and chemical stability – positions Aluminum Nitride as an ideal solution for demanding industries.

Key Features of Aluminum Nitride Products

• Exceptionally high thermal conductivity (up to 180–220 W/m·K)
• Excellent electrical insulation even at high temperatures
• High mechanical strength and fracture toughness
• Low thermal expansion coefficient (close to silicon)
• Outstanding thermal shock resistance
• Good chemical resistance to most molten metals and corrosive environments
• Non-toxic and environmentally friendly• High purity and low outgassing for semiconductor and vacuum applications

Applications of Aluminum Nitride Products

• Thermal management substrates and heat sinks for high-power electronics
• Components for semiconductor processing equipment (heater plates, chucks, focus rings)
• LED packages, laser diode submounts, and optoelectronic components
• RF and microwave communication systems (5G, satellite)
• Aerospace and defense electronics requiring thermal stability and insulation
• Medical imaging devices (CT scanners, MRI equipment)
• Industrial equipment operating under high temperatures and corrosive conditions

At AdValue Technology, we provide both direct-sintered and hot-pressed Aluminum Nitride products, tailored to each customer’s application needs. Our Aluminum Nitride components can be customized in a wide range of sizes and shapes to suit precise specifications.

We also offer Aluminum Nitride substrates made by tape casting method. With thermal conductivity exceeding 170 W/m·K, AlN is one of the best heat-spreading materials available among electrically insulating ceramics, making it ideal for demanding thermal management applications.
