Alumina ceramic, also called Al2O3 ceramic, is one of the most practical materials for custom technical ceramic parts. It is hard, insulating, temperature resistant and suitable for many drawing-based components.

Common buyer need: replace a metal, plastic or lower-grade ceramic part with a harder insulating component that can fit an existing assembly.

Alumina Ceramic Wear Parts

For wear applications, alumina can be made into guide pins, rods, sleeves, washers, plungers, rings and sliding contact parts. Final grinding or polishing can be used for critical surfaces.

Alumina Ceramic Insulation Parts

Alumina is also selected for electrical insulation, high-voltage spacing and furnace-related parts. Typical shapes include tubes, spacers, washers, sleeves, plates and custom insulators.

Typical Custom Shapes

  • Alumina rods, shafts, pins and plungers.
  • Alumina tubes, insulating sleeves and spacers.
  • Alumina ceramic rings, washers and bushings.
  • Custom ceramic fixtures, plates and support parts.

Design and Cost Factors

Cost depends on size, shape, tolerance, surface finish, forming method and quantity. Mark only truly critical dimensions as tight tolerance. Chamfers and reasonable wall thickness can improve yield and reduce chipping.
