Macor® Board
Macor® has low thermal conductivity. This outstanding insulating material remains continuously stable at 800 °C, with a maximum peak at 1,000 °C. Final Advanced Materials can supply rods with square or round section for your own use.
Macor® square boards are mostly used in the aeronautic, nuclear and welding industry or for the making of props.
They are available in dimension of 50, 100, 150 and 300 mm and thickness ranging from 5 to 55 mm.

- Macor® board, 5 to 55 mm thick
Macor is a machinable vitroceramic with a density of 2.52 g/cm3 and capable of resisting temperatures up to 1,000°C for a short term. Macor stands out for its excellent machinability when dry, and by its low thermal conductivity (1.46 W/(m·K)), making it an effective insulator for high temperatures, and an excellent electrical insulator.
Shapal Hi-M Soft has a high thermal conductivity (92 W/(m·K)) and good mechanical properties. Shapal Hi-M Soft is slightly more difficult to machine than Macor but is excellent for heat dissipation.
Final Advanced Materials recommends Macor for prototyping or complex parts with a maximum continuous temperature of 800°C and a short-term temperature of 1,000°C, and Shapal Hi-M Soft for challenging thermal applications.
Among machinable ceramics, Macor stands out for its high dielectric strength of 45 kV/mm, resistivity of 1015 Ω.m and dielectric constant of 6.01 (at 20°C and 1 MHz). Macor remains stable up to 1,000°C, making it the ideal solution for high-temperature insulators and electronic substrates. For applications where the top priority is high-temperature electrical insulation, Final Advanced Materials therefore recommends Macor for its dielectric stability and its low dielectric loss.
