Medical Devices: Alumina ceramics are widely used for medical equipment such as surgical instruments and diagnostic machines, where their biocompatibility and non-reactivity are critical.
Semiconductors: These components can be used in semiconductor manufacturing for handling or positioning sensitive materials, providing excellent insulation and thermal stability.
Industrial Equipment: Due to their mechanical properties, alumina arms are used in industrial robots or machinery, especially where precision is key.

Processing Challenges

Machining Precision: Alumina ceramics require extremely precise machining, particularly with advanced CNC equipment, to achieve the tight tolerances necessary for functional components.
Tool Wear: High hardness and abrasiveness of alumina lead to rapid wear of cutting tools. Specialized tools and coatings are often required to ensure machining efficiency.
Brittleness: Alumina ceramics are brittle, making the material prone to cracking or chipping during machining. Proper handling, cutting, and cooling processes must be employed to avoid damage.
Surface Finish: Achieving a smooth surface finish on alumina ceramics can be challenging, as polishing and grinding must be carried out with care to avoid imperfections.
