Today, we continue to discuss the performance characteristics of 99% aluminum oxide.

Compared to 96% aluminum oxide, 99% aluminum oxide is a high-quality material with a very high purity of aluminum oxide and minimal chemical impurities. It is mainly used in ceramic PCB that require excellent mechanical, electrical, thermal performance, or corrosion resistance to cope with harsh operating environments. Here are the main advantages of 99% aluminum oxide material:

1. Uniform heating and rapid heat dissipation: Due to its superior thermal conductivity compared to 96% aluminum oxide, 99% aluminum oxide ensures uniform heating of the material and aids in efficient heat dissipation. This characteristic is particularly important for industrial equipment that generates a lot of heat during operation.

2. Smooth surface and high mechanical strength: The 99% aluminum oxide material has a smooth surface, which enhances its mechanical strength. This ensures that the material remains robust and less susceptible to damage during use.

3. Acid and alkali corrosion resistance: Due to its high purity, 99% aluminum oxide material exhibits excellent resistance to acid and alkali corrosion, ensuring the material's long service life and safety in corrosive environments.

4. Precision and accuracy: The higher purity of 99% aluminum oxide material results in better precision and stability in various electrical performance characteristics. This feature is particularly advantageous in the manufacturing of electronic devices that require high performance and precision.

Now that we have confirmed the properties of both materials, in the cover image, we compare 96% and 99% aluminum oxide materials side by side to clearly highlight their differences.
