Product Overview<\/b><\/strong><\/h3>\n

Aluminum Nitride (AlN) Ceramic Discs, also known as precision perforated ceramic rings, are high-performance materials made from aluminum nitride (AlN) ceramics. These discs are characterized by excellent thermal conductivity, electrical insulation, and thermal stability. The precise perforation design enhances their heat dissipation capabilities, while also providing structural support and optimal thermal management. With high purity and outstanding physical stability, these ceramic discs play a crucial role in a variety of high-end applications, particularly in high-temperature, high-pressure, and electrically insulated environments.<\/p>\n

Features<\/b><\/strong><\/h3>\n
    \n
  • High Thermal Conductivity & Electrical Insulation<\/strong>: AlN ceramic discs have a thermal conductivity of up to 170 W\/m\u00b7K and a dielectric breakdown strength of 17-19 KV\/mm, making them ideal for environments that require both heat dissipation and electrical insulation.<\/li>\n
  • Precision Perforation Design<\/strong>: The discs feature precise perforations that enhance heat dissipation and allow for the flow of gases or liquids, optimizing thermal management in devices.<\/li>\n
  • Low Thermal Expansion Coefficient<\/strong>: The thermal expansion coefficient ranges from 3.2-3.4\u00d710<sup>-6<\/sup>\/\u00b0C, closely matching some metals and semiconductor materials, which helps reduce mechanical stress due to temperature differences.<\/li>\n
  • Exceptional Physical Stability<\/strong>: These discs can withstand operational temperatures up to 1000\u00b0C and have excellent thermal shock resistance, ensuring reliable performance in high-temperature environments.<\/li>\n
  • Uniform Appearance & High Purity<\/strong>: With a smooth surface and consistent gray-white color, the discs reduce friction and improve contact efficiency.<\/li>\n<\/ul>\n

    Applications<\/b><\/strong><\/h3>\n
      \n
    • Electronics Cooling<\/strong>: Widely used in power semiconductors, power LEDs, and high-performance computing equipment to ensure effective heat dissipation and stable performance.<\/li>\n
    • Electrical Insulation & Structural Support<\/strong>: Provides mechanical support and electrical insulation, particularly suitable for high-temperature or fluctuating operational environments.<\/li>\n
    • Chemical & Medical Equipment<\/strong>: Due to their chemical stability and high-temperature resistance, these discs are ideal for chemical and medical devices that need to withstand stringent sterilization and cleaning processes.<\/li>\n
    • Precision Machinery & Optical Equipment<\/strong>: Used in high-precision, thermally stable equipment such as laser systems and high-end optical devices, providing reliable support.<\/li>\n<\/ul>\n
