Yes! Alumina can be polished to a submicron-level surface roughness (Ra < 0.1 μm) using
diamond lapping and fine grinding.
Lead times depend on part complexity and quantity, but standard orders typically take 2-4
weeks. For urgent projects, expedited manufacturing options are available.
Alumina offers higher hardness and thermal resistance than many ceramics. Compared to
Zirconia (ZrO₂), Alumina is more thermally stable. Compared to Silicon Carbide (SiC), it is
more electrically insulating.
Yes! We offer custom Alumina compositions and tolerances for unique applications.

Because Alumina is brittle and hard, the best techniques include diamond grinding, ultrasonic-assisted machining, and high-precision CNC milling.
Alumina is used in high-precision machining for electronics, aerospace, and medical devices, thanks to its high strength, temperature resistance, and electrical insulation.
