Product Description

Product Description

Grey Color 170W/M. K Aluminium Nitride Ceramic Plate Aln Board

This AlN ceramic board blank supports custom CNC machining. Combining high thermal conductivity and superior electrical insulation, it is widely used for high power device thermal insulation gaskets, sensor bases, semiconductor fixture parts and electronic thermal management components.

Aluminum Nitride Board

Ultra-high Heat Conduction
Thermal conductivity reaches ≥170 W/(m·K), enabling uniform temperature distribution under high-temperature working environments. It avoids local hot spots and extends the service life of gas injection components.
 
Excellent Electrical Insulation Performance
Volume resistivity ≥10^14Ω·cm, dielectric strength ≥15 kV/mm, matched with stable dielectric constant 9.0 at 1MHz. It blocks current leakage perfectly under high-frequency & high-voltage working conditions.
 
Excellent  Mechanical & Thermal Matching Property
Flexural strength ≥330 MPa guarantees structural stability during cutting and machining; low thermal expansion coefficient 4.4×10^-6/℃ effectively relieves thermal stress variation caused by temperature fluctuation, and prevents cracking under long-term temperature cycles.

Aluminum Nitride Ceramic Board

Q1:Can these AlN ceramic boards be CNC machined to custom dimensions or features?
 
A1:Yes. Our AlN blanks can be CNC processed for inner holes, notches and special profiles. Custom diameters, thicknesses and tolerances are available against drawings.
 

Q2:How about the insulation safety under high voltage & high frequency working conditions?

A2: It has volume resistivity ≥10^14 Ω·cm and dielectric strength ≥15 kV/mm, with a stable dielectric constant of 9.0 and low dissipation factor (3×10^-4@1MHz). It effectively isolates current leakage and breakdown risks for high-frequency power equipment.
