Product Summary of MACOR® machineable glass ceramic

Traditional ceramic materials can normally only be machined by diamond grinding once they have been fired, which can be costly. MACOR® machineable glass ceramic offers a potentially lower cost solution to this problem.

MACOR® can be quickly, accurately and economically machined into high-precision components using ordinary metalworking tools, and does not require any post-firing after machining has been completed, removing a production process, reducing manufacturing time and potentially reducing costs.

Characteristics of MACOR® machineable glass ceramic include:

  • Maximum use temperature of 1000°C
  • Strong and rigid
  • Good electrical and thermal insulation
  • Zero porosity
  • Radiation resistant
  • Low thermal conductivity
  • Can be highly polished
