Erosion Resistant Aluminum Nitride AlN Ceramic Rod

The aluminum nitride (AlN) ceramic has high thermal conductivity(5-10 times as the alumina ceramic), low

dielectric constant and dissipation factor, good insulation and excellent mechanical properties, non-toxic,

high thermal resistance, chemical resistance ,and the linear expansion coefficient is similar with Si,which is

widely used in communication components, high power led, power electronic devices and other

fields.Special spec products can be produced upon requests.

PRODUCT PERFORMANCE

– High thermal conductivity, high flexural strength, high temperature
– Good electrical insulation
– Low dielectric constant and loss

– Able to be laser drilled, metallized, plated and brazed

Aluminum Nitride is one of the few materials that offers electrical insulation and high thermal conductivity. This makes AlN extremely useful in high power electronic applications in heat sink and heat spreader applications.

Aluminum Nitride (AlN) is an excellent material to use if high thermal conductivity and electrical insulation properties are required. Because of it’s qualities, it is an ideal material for use in thermal management and electrical applications.
Some common applications of Aluminum Nitride include the following: Heat sinks & heat spreaders Electrical insulators for lasers Chucks, clamp rings for semiconductor processing equipment Electrical insulators Silicon wafer handling and processing Substrates & insulators for microelectronic devices & opto electronic devices Substrates for electronic packages Chip carriers for sensors and detectors Chip lets Collets Laser heat management components Molten metal fixtures Packages for microwave devices
