C-Component - Aluminum Nitride (AlN) Ceramic Substrates

SHARE

С-Компонент specializes in the production of aluminum nitride (AlN) ceramic substrates, known for their exceptional thermal conductivity and excellent electrical insulation properties. These substrates are critical for electronic, optical, and renewable energy applications due to their near-silicon thermal expansion coefficient and high radiation resistance. Unlike toxic beryllium oxide (BeO) substrates, AlN maintains its thermal conductivity even at elevated temperatures, making it a safer and more efficient alternative. Available in thermal conductivities of 170, 200, or 230 W/m·K, these substrates can be custom-fabricated to precise specifications, including complex contours, holes, and surface finishes. With reliable production and consistent batch-to-batch quality, С-Компонент ensures optimal supply efficiency and cost-effectiveness.

S-Component manufactures substrates based on aluminum nitride (AlN), ensuring minimal prices and delivery times with consistently high quality.

Aluminitride ceramics are always available in our warehouse and can be quickly processed to the desired design, including any complex contours, hole drilling, ablation, grinding and polishing. Substrates are manufactured according to TU 3493-001-86724983-2016.

Aluminum nitride (AlN) is a ceramic material with a unique combination of high thermal conductivity and excellent electrical insulation properties, while having a coefficient of thermal expansion close to silicon. Aluminitride ceramics have high chemical inertness and excellent radiation resistance. Aluminum nitride substrates are the best alternative to toxic beryllium oxide (BeO), the thermal conductivity of which decreases significantly with increasing temperature, while a similar decrease in the thermal conductivity of aluminum nitride is insignificant. All this makes aluminum nitride a critically important material for many promising applications in the field of electronics, optics and renewable energy sources. Depending on the task, you can place an order for AlN products with a thermal conductivity of 170 W / m K (standard, optimal price), 200 W / m K or 230 W / m K * in the desired geometric design. Our production will ensure careful manufacturing in compliance with all required tolerances and repeatability from batch to batch.
