Overview of aluminum nitride ceramics

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of aluminum nitride ceramics

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

5 FAQs of 2.5mm Thick Customized Aluminium Nitride/AlN Ceramic Sheet

What is Aluminium Nitride used for?
Aluminium Nitride (AlN) ceramic sheets work well in high-tech fields. They handle extreme heat, insulate electricity, and resist corrosion. Common uses include electronics, LED lighting, semiconductor parts, and heat sinks. Their thermal conductivity makes them ideal for managing heat in devices that need fast cooling.

Can AlN sheets be customized for specific needs?
Yes. We machine AlN sheets to match exact requirements. Custom shapes, sizes, holes, or surface finishes are possible. CNC tools ensure precision. Tell us your design details, and we produce sheets that fit your project.

How does 2.5mm thickness affect performance?
The 2.5mm thickness balances strength and heat transfer. Thinner sheets might break easily; thicker ones add unnecessary weight. This size suits most industrial uses. It provides enough durability for handling and installation while keeping heat dissipation efficient.

Is AlN better than alumina ceramics?
AlN conducts heat 8-10 times better than alumina. This makes it superior for applications needing quick heat removal. Alumina costs less but works poorly in high-power systems. AlN’s higher price is justified for projects where overheating risks matter.

How should AlN sheets be stored and handled?
Store AlN sheets in dry, room-temperature areas. Avoid moisture and direct sunlight. Handle gently—AlN is hard but brittle. Use gloves to prevent scratches. Clean surfaces with alcohol before installation. Follow safety guidelines to avoid cracks during setup.
