Aluminum nitride ceramic washers

  • Aluminum nitride ceramic spacers have high thermal conductivity and electrical insulation, so they can be used in various electronic devices.


Advantages Of Aluminum nitride ceramic washers

Aluminum nitride ceramic washers has high thermal conductivity, low expansion coefficient, high strength, high temperature resistance, chemical corrosion resistance, high resistivity, and low dielectric loss. It is an ideal high temperature insulation ceramic product.AIN ceramics can replace toxic beryllium oxide ceramics and are widely used in the electronics industry.

Aluminum nitride ceramic washers Applications

Aluminum nitride (AlN) ceramics have high thermal conductivity and electrical insulation, so they can be used in various electronic devices. The thermal conductivity of aluminum nitride is more than 170W/(mk), it has good thermal shock resistance, and can be used in a high temperature environment of 2200℃.. Therefore, aluminum nitride ceramic products are an ideal choice for many industries, such as:

  • Heat sinks & heat spreaders
  • Substrates for electronic packages
  • Substrates & insulators for microelectronic devices & opto electronic devices
  • Laser heat management components
  • Electrical insulators
  • Molten metal fixtures

Aluminum nitride (AlN) Basic Information

Aluminum nitride (AlN) is a covalent bond compound, atomic crystal, diamond-like nitride, hexagonal system, wurtzite crystal structure, non-toxic, white or grey white.

  • Very high thermal conductivity (> 170 W/mK);

  • High electrical insulation capacity (>1.1012Ωcm);

  • Strength according to the double ring method >320 MPa (biaxial strength);

  • Low thermal expansion 4 to 6×10-6K-1(between 20 and 1000°C);

  • Good metallization capacity.
