Aluminum Nitride Rod High Thermal Conductivity for Electronics & Semiconductor Cooling

Product Features

Aluminum nitride rod stands as a premium ceramic component engineered for high-temperature, high-thermal-conductivity scenarios, with customizable specifications to meet diverse industrial demands. Crafted from high-purity aluminum nitride (AlN) powder via advanced hot isostatic pressing (HIP) and precision machining, it integrates exceptional thermal conductivity, superior electrical insulation, and robust mechanical strength—outperforming traditional ceramic tubes like alumina and silicon carbide in critical applications. Widely adopted in semiconductor manufacturing, industrial heating, aerospace, and electronics cooling, this custom aluminum nitride rod delivers reliable performance under extreme conditions while adapting to unique design requirements.

The core advantage of our aluminum nitride rod lies in its material superiority, which forms the foundation for customization. With a purity range of 95% to 99.9% (customizable by purity grade), it achieves thermal conductivity of 150-200 W/(m·K)—5-8 times that of alumina tubes and 2-3 times that of silicon carbide tubes. This high thermal conductivity aluminum nitride tube efficiently transfers heat, making it ideal for heat dissipation in high-power electronic components. Meanwhile, its volume resistivity exceeds 10¹⁴ Ω·cm at room temperature, maintaining excellent electrical insulation even at 800℃—a critical trait for applications requiring both heat transfer and electrical isolation, such as semiconductor wafer processing fixtures.

Unmatched customization capabilities set our aluminum nitride tube apart, covering dimensions, surface treatments, and performance tuning. For outer diameter, we offer 5mm to 200mm options, with inner diameter ranging from 3mm to 180mm and length customizable up to 1000mm—supporting both standard sizes and non-standard designs for specialized equipment. Wall thickness tolerance is controlled within ±0.1mm via precision grinding, ensuring tight fits for assembly. 

Our aluminum nitride rod excels in extreme environmental resistance, a key benefit for customized industrial applications. It operates stably across a temperature range of -200℃ to 1200℃, with no thermal shock failure when subjected to rapid temperature changes (ΔT = 500℃). Its coefficient of thermal expansion (CTE) of 4.5×10⁻⁶/℃ matches that of silicon and gallium arsenide, making it ideal for semiconductor packaging tubes that require thermal compatibility with chips. Exceptional chemical resistance resists corrosion from acids (except hydrofluoric acid), alkalis, and molten metals, suiting custom applications in chemical processing and metallurgy.

Versatile custom applications span high-tech industries. In semiconductor manufacturing, custom aluminum nitride tubes serve as wafer transport tubes and plasma etching chamber liners, with 99.5% purity variants preventing metal ion contamination. Industrial heating systems use them as heating element sleeves, where high thermal conductivity ensures uniform heat distribution and 1200℃ resistance handles high-temperature operations. Aerospace applications include satellite thermal management tubes, customized to lightweight designs (density 3.26 g/cm³) for fuel efficiency.

In electronics cooling, high thermal conductivity aluminum nitride tubes act as heat pipes for high-power LED arrays and EV battery modules, with custom inner grooved designs enhancing heat transfer efficiency by 30%. Medical equipment benefits from biocompatible variants (custom surface passivation) used in MRI machine cooling tubes, complying with ISO 10993 standards. For renewable energy, custom tubes with anti-oxidation coatings serve as solar panel thermal management components, withstanding outdoor temperature fluctuations.
