                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
