Design Features

High Insulation Performance: 

Polished insulating aluminum nitride ceramics possess excellent electrical insulation properties and a low dielectric constant, 

making them suitable for use in electronic and electrical equipment to prevent short circuits and current leakage.

Good Thermal Conductivity: 

Despite its high insulation properties, aluminum nitride ceramics maintain good thermal conductivity, aiding in heat dissipation 

and preventing overheating.

High Temperature Resistance: 

This material can withstand high-temperature operating environments, with operating temperatures exceeding 1000°C, ensuring 

its stability under high-temperature conditions.

Mechanical Strength: 

Aluminum nitride ceramics have high mechanical strength, are not easily deformed, and are wear-resistant, making them suitable 

for complex applications.

Smooth Surface: 

Through polishing, the surface is smooth and burr-free, increasing aesthetics and reducing frictional losses caused by surface roughness.

Lightweight Design: 

Compared to traditional metal materials (steel, iron, etc.), aluminum nitride ceramic sheets have a lower density, reducing the 

overall weight of the equipment.
