Polished insulating aluminum nitride sheet
Alias: Aluminum nitride ceramic heat-sink sheet

Description：

Polished insulating aluminum nitride ceramic sheet is a precision ceramic material with high insulation properties, excellent mechanical strength and high temperature resistance. Its main component is aluminum nitride (AlN), which is treated with a special polishing process to achieve a smooth surface with extremely high surface flatness and wear resistance. This type of ceramic sheet is widely used in industries that require high insulation and excellent thermal conductivity, such as electronics, semiconductors, optoelectronic equipment, etc.
Aluminum nitride ceramic products have attracted much attention due to their excellent physical properties and chemical stability. In industry and technology, aluminum nitride ceramics are often used to manufacture components at high temperatures and pressures. Its high strength, corrosion resistance, and excellent thermal conductivity make it the material of choice for aerospace, energy, and more. In addition, aluminum nitride ceramics are also widely used in the manufacture of chemical equipment and electronic devices, and their chemical inertness and high-temperature stability provide reliable support for these applications.

Features:

1. High Insulation Properties:
Polished insulating aluminum nitride ceramics have excellent electrical insulation properties and low dielectric constant, making them suitable for use in electronic and electrical equipment to avoid current short circuits and current leakage.

2. Good thermal conductivity:
Despite its high insulation, aluminum nitride ceramics maintain good thermal conductivity, helping to dissipate heat and prevent equipment from overheating.

3. High Temperature Resistance:
The material can withstand high-temperature working environments, reaching temperatures above 1000℃, ensuring its stability under high-temperature conditions.

4. Mechanical Strength:
Aluminum nitride ceramics have high mechanical strength, are not easy to deform, and are resistant to wear, making them suitable for complex applications.

5. Smooth Surface:
The polishing process results in a flat and burr-free surface, which increases aesthetics and reduces frictional losses due to rough surfaces.

6. Lightweight design:
Compared with traditional metal materials (steel, iron, etc.), aluminum nitride ceramic sheets have a lower density, reducing the weight burden of the overall equipment.

Applications:

1. Electronics Industry:
It is widely used in electronic components, integrated circuit (IC) packaging, electronic device substrates, and other fields, providing efficient electrical insulation performance and thermal management.

2. Semiconductor Industry:
In the semiconductor manufacturing process, as a heat dissipation material, aluminum nitride ceramic sheets help dissipate heat from equipment and extend the service life of equipment.

3. Optoelectronic Equipment:
Aluminum nitride ceramic sheets can work for a long time in high-temperature environments and are widely used in optoelectronic fields such as LED lighting, lasers, and optical sensors.

4. Power and High Voltage Equipment:
As an insulating material for high-voltage electrical appliances, aluminum nitride ceramics are widely used in power equipment, such as transformers, switchgear, fuses, etc.

5. Aerospace & Aviation:
Due to its excellent high-temperature resistance and high-strength characteristics, polished aluminum nitride ceramic sheets are also widely used in the aerospace field, especially in high-temperature and high-pressure working environments.

6. Automotive Industry:
In the electronic control system of new energy vehicles and traditional vehicles, aluminum nitride ceramics play a role in protection and heat dissipation as a high-quality insulation and thermal management material.
