Aluminum Nitride Tube Features
The characteristics of aluminum nitride material itself are fully utilized, and after being processed into ceramic tubes, they are used in corresponding scenarios, especially in thermal management and electrical applications.
-High thermal conductivity;
-High mechanical strength under compression load；
-Good thermal shock resistance；
-Low coefficient of thermal expansion；
-Good electrical insulation and resistivity；
-Low dielectric constant.

Aluminum Nitride Tube Applications
-Cooling systems for equipment requiring heat dissipation;
-Thermal insulation sleeves for devices.
– Semiconductor electronic device reactors;
AlN ceramic tubes are used in many industrial fields such as electronics, electricity, locomotives, aerospace, national defense and military industry, communications, etc., and have broad potential markets in laser technology and new energy.
At 25°C, the thermal conductivity of AlN (200W/mK) is 6.7 times that of aluminum oxide (30W/mK); at 300°C, AlN still maintains >180W/mK, while aluminum oxide drops to 15W/mK. This allows AlN tubes to reduce thermal management energy consumption by 40% in semiconductor equipment.
Yes. Through gel casting combined with ultra-precision grinding, we can produce microtubes with an inner diameter of 0.5 mm and a wall thickness of 0.1 mm, with a roundness tolerance of ≤ 0.005 mm. These are suitable for medical laser catheters and MEMS sensor packaging.
Pre-metallization treatment is possible. Active brazing (Ag-Cu-Ti alloy) is used to achieve a welding strength of >50MPa between AlN and Kovar alloy, meeting the vacuum chamber sealing requirements .
