Aluminum Nitride (AlN)

Product Overview
Aluminum Nitride (AlN) is a ceramic material with exceptional thermal conductivity, high density, and outstanding thermal shock resistance. Its thermal conductivity is 2 to 3 times that of aluminum oxide, and it possesses excellent high-temperature and corrosion resistance properties, especially against molten metals like aluminum. AlN is widely used in the electronics industry and high-temperature applications, maintaining stability even in harsh environments.

Key Features

• Excellent Thermal Conductivity: Its thermal conductivity is 2 to 3 times higher than that of aluminum oxide, making it ideal for applications requiring efficient heat transfer.
• High Strength and Thermal Shock Resistance: It retains strength in high-temperature conditions, suitable for use in high-temperature environments.
• High-Temperature and Corrosion Resistance: Stable in high-temperature and harsh environments, with strong resistance to the corrosion of molten aluminum.
• Good Electrical Insulation: Provides good electrical insulation properties, making it suitable for electronic packaging materials.

Applications

• Electronics Industry: Used in the production of integrated circuit substrates, electronic devices, optical devices, and heat sinks.
• High-Temperature Materials: Employed in high-temperature crucibles, thermally conductive silicone rubber, thermal silicone, and thermally conductive plastics.
• Composite Materials: Used in metal-based and polymer-based composites, such as high-temperature sealants and electronic packaging materials.
• Mechanical and Military Applications: Used in lubricants, anti-wear agents, microwave dielectric materials, and thermocouple protection tubes.
• Other Specialized Applications: Applied in semiconductor crucibles, evaporation boats, and surface acoustic wave devices.
