Al₂O₃ Ceramics Machining Services

Precision CNC Machining for 95%, 99%,99.5%,and 99.8% Al₂O₃ Components with Tight Tolerances and Fast Turnaround

Materials We Support

We specialize in machining various grades of alumina ceramics, including:

  • 95% Alumina – cost-effective, general-purpose

  • 99% Alumina – high-purity for mechanical and thermal applications

  • 99.5% Alumina – ideal for demanding vacuum and electronic insulation environments

  • 99.8% Ultra-Pure Alumina – available upon request for semiconductor and medical use

Our experience covers a wide range of part sizes, shapes, and material hardness.

Machining Capabilities

With our advanced equipment and rich experience in machining, we can achieve:

  • Processing accuracy as low as 0.001mm
  • Flatness accuracy up to 0.002mm
  • Surface roughness (Ra) as low as Ra0.02um
  • Micro-hole drilling as small as 0.16mm diameter
  • Custom-shaped parts, slots, grooves, and thin walls
  • No-crack edge finishing and complex contours

We handle everything from rapid prototyping to small- and medium-volume production runs.
