Product FAQ's

Are Aluminum Nitride discs the same as Aluminum Nitride plates?

Yes, many manufacturers refer to flat AlN components as Aluminum nitride plates or substrates.
The main difference is shape:

Aluminum nitride plate – rectangular or square shape
Aluminum nitride disc – round/circular shape

Both offer the same performance properties depending on thickness and purity.

What affects the Aluminum nitride plate price?

Ans: The Aluminum nitride plate price (including discs and substrates) depends on:

Diameter or plate size
Thickness
Purity and density
Polished vs. unpolished surface
Custom machining or drilled holes
Quantity ordered

Higher-density, polished Aluminum nitride substrates cost more due to tighter tolerances.

Do Aluminum Nitride discs offer electrical insulation?

Yes. Aluminum nitride is an excellent dielectric material. Aluminum nitride substrates are used in power modules and RF components because they provide both:

High electrical insulation
High thermal conductivity

This makes AlN discs superior to alumina in high-power applications.

Are custom Aluminum Nitride plates and discs available?

Yes. Custom options include:

Specific diameters
Precise thickness tolerances
Polished surfaces (Ra < 0.2 µm available)
Laser-cut holes or slots
Machined edges

This is ideal for custom Aluminum nitride substrate requirements.

Where can I find Aluminum nitride discs or substrates for sale?

You can find Aluminum nitride discs, plates, and substrates for sale from specialized ceramic manufacturing companies and semiconductor material suppliers. Choosing the right Aluminum nitride substrate supplier ensures consistent purity, machining accuracy, and reliable delivery times.

How long is the delivery time for Aluminum Nitride discs?

Delivery varies based on stock and custom specifications:

Stock discs/plates: 3–7 business days
Custom discs or substrates: 2–5 weeks
Large-volume orders: scheduled production

A reputable supplier will provide clear timelines and support.
