Polished alumina is a specially treated alumina material that achieves an extremely smooth surface through polishing techniques while maintaining the excellent properties of alumina itself.

In the field of optics: With its high transparency and low roughness surface, it is commonly used to manufacture precision optical components such as optical lenses and lenses. For example, in high-end camera lenses, polished alumina can effectively reduce light scattering, improve imaging clarity and color reproduction.

Precision instrument manufacturing: Due to its excellent wear resistance and dimensional stability, it is often used to manufacture high-precision mechanical components, such as the casing of gyroscopes and sealing rings for aircraft engines. These components require extremely high precision and surface quality, and polished alumina can meet their stringent requirements.

Decorative materials: Due to their beautiful appearance and corrosion resistance, they are widely used in the field of architectural decoration, such as making high-end indoor and outdoor decorative panels, decorative strips, etc. In the decoration of some high-end hotels and office buildings, polished alumina decorative elements can enhance the overall sense of luxury and modernity.
