ALN part

Thermal Conductivity: Standard grade ≥170 W/m·K, high thermal grade up to 230 W/m·K, 7–10x higher than alumina ceramic, rapidly export heat of high-power chips to reduce junction temperature by 12–18℃
Density: 3.25–3.32 g/cm³, zero water absorption, fully dense microstructure
Electrical Insulation: Dielectric strength ≥15 kV/mm, volume resistivity ≥10 14Ω·cm, low dielectric loss 3×10 -4 @1MHz, stable insulation under 1000V high frequency
Thermal Expansion Coefficient (CTE): 4.4×10-6/K, highly matched with silicon/SiC/GaN chips, effectively eliminate thermal stress cracking during cold & heat cycles
Mechanical Property: Flexural strength ≥330 MPa, Vickers hardness 1100–1200 HV, excellent wear & corrosion resistance, long service life over 20,000 working hours

Aluminum Nitride (AlN) Ceramic Precision Custom Parts

Q1: What thermal conductivity grades of AlN custom parts can you supply? What's the difference?
Standard grade: 170–180 W/m·K, cost-effective for general power modules, LED heat sinks
High thermal grade: 190–210 W/m·K, for SiC/GaN third-generation semiconductors, high-frequency RF equipment
Ultra-high thermal grade: 220–230 W/m·K, for high-power laser, semiconductor wafer heating plates 
All grades provide independent thermal conductivity test reports.

Q2: What's the difference between AlN and alumina ceramic custom parts?
A: Alumina thermal conductivity only 20–30 W/m·K, AlN is 7–10 times higher; AlN has lower CTE matching silicon chips, higher insulation voltage, better anti-thermal shock performance, suitable for high-power miniaturized electronic products, while alumina is only for low-power low heat scenarios.
