GORGEOUS CERAMICS (GGS Ceramic) is an advanced manufacturer specializing in precision ceramic machining. We focus on the research and development and production of high-performance aluminum nitride ceramic heat sinks, providing reliable customized heat dissipation solutions for industries such as semiconductors, power electronics, new energy, communications, laser equipment, and medical equipment.
Compared to metal heat sinks, aluminum nitride ceramics not only possess near-metal thermal conductivity but also electrical insulation properties that metal heat sinks lack, allowing them to be used directly as insulating heat dissipation structural components.
We offer free samples of aluminum nitride ceramics. Custom designs based on provided drawings are also available, offering various complex structures, high-precision machining processes including metallization and brazing, to meet the diverse needs of our clients.
Features of aluminum nitride radiators
Conduttività termica superiore
Aluminum nitride typically boasts a thermal conductivity of up to 200 W/m·K (25℃), several times that of alumina ceramics. This makes it particularly advantageous for high-power applications compared to alumina heat sinks.
Electrical Insulation Properties
If your application operates in a high-voltage environment, aluminum nitride heat sinks maintain stable insulation properties, allowing direct cooling of power electronic devices without the need for additional insulation layers.
Matching Thermal Expansion Coefficient with Chip Materials
If your application involves the semiconductor industry, aluminum nitride heat sinks are ideal. Aluminum nitride’s thermal expansion coefficient is very close to that of semiconductor materials such as silicon (Si) and silicon carbide (SiC), effectively reducing thermal stress and minimizing the risk of chip cracking.
High Temperature and Corrosion Resistance
If your application operates in a high-temperature environment for extended periods, aluminum nitride heat sinks are also suitable because aluminum nitride is resistant to oxidation and corrosion by most chemical media.
Applications of aluminum nitride heat sinks
For New Energy Vehicles
Aluminum nitride (ANT) heat sinks can be used in various power modules of new energy vehicles, such as IGBT modules, SiC power modules, and OBC on-board chargers, helping to stabilize heat dissipation and extend the lifespan of electronic modules.
GORGEOUS CERAMICS (GGS Ceramic) has collaborated successfully with new energy vehicle component suppliers multiple times, and the project has entered the mass production stage. We have customized dedicated ANT ceramic heat sink base plates for power modules, effectively improving module heat dissipation efficiency and significantly reducing thermal stress.
For Semiconductor Equipment
ANT heat sinks can be used as heat dissipation base plates for power modules, as heat dissipation components for vacuum equipment, and as heat dissipation platforms for wafer equipment. A semiconductor equipment company has ordered multiple batches of customized ANT insulated heat dissipation structures from GORGEOUS CERAMICS (GGS Ceramic), which perfectly solve the heat dissipation problem inside vacuum equipment.
We provide one-stop solutions for the semiconductor industry, supplying high-insulation, high-dimensional-precision ceramic structural components.
Used in the telecommunications industry
Aluminum nitride ceramic heat sinks can also be used in the telecommunications industry, such as in 5G power amplifiers, RF modules, and microwave communication equipment, all of which require excellent heat dissipation conditions to ensure long-term stable operation.

Which industries are suitable for aluminum nitride ceramic heat sinks?
The main application industries for aluminum nitride ceramic heat sinks include semiconductor equipment, SiC/GaN power devices, IGBT power modules, new energy vehicle electronics, lasers and optical communication equipment, 5G communication equipment, power electronic equipment, medical electronic equipment, and aerospace electronic systems.
What is the difference between aluminum nitride and alumina heat sinks?
The biggest difference between alumina and aluminum nitride heat sinks lies in their thermal conductivity. Aluminum nitride ceramics have a thermal conductivity several times that of alumina ceramics, making them more suitable for high-power, high-heat-flux-density equipment. Alumina ceramics, on the other hand, are less expensive and suitable for low- to medium-power electronic products. If your application requires high heat dissipation efficiency, GORGEOUS CERAMICS (GGS Ceramic) recommends using aluminum nitride ceramic heat sinks.
What custom processing services does GORGEOUS CERAMICS (GGS Ceramic) offer?
We support a variety of customization services, including: custom processing, sample processing, OEM/ODM, CNC precision machining, irregular shape machining, micro-hole machining, deep hole machining, ultra-thin machining, metallization, brazing, nickel plating, gold plating, and other surface treatments.
Can aluminum nitride ceramic radiators be connected to metals such as copper and aluminum?
Yes. Depending on your specific application, we can perform metallization, active brazing, DBC/AMB, and other processes to achieve a reliable connection between aluminum nitride ceramics and copper, aluminum, or other metal components.
How to choose the right aluminum nitride ceramic radiator?
GORGEOUS CERAMICS (GGS Ceramic) recommends that you consider the following factors based on your actual application: heating power, operating temperature, whether high thermal conductivity is required, whether insulation is required, product dimensions, installation method, and operating environment (vacuum, corrosive media, etc.). If you provide drawings or application parameters, we can assist you in evaluating material specifications and processing solutions and provide customization suggestions.
