Machinable Ceramics
 |
 |
 |
 |
MacGlass Ceramic is the traditional machinable ceramic used for years for making prototype and low volume production of ceramic parts. It can be milled, drilled, tapped, turned, sawed, ground or polished using conventional carbide tooling to tolerance of 0.0005". MacGlass Ceramic, usable to 1800°F (1000°C), is non porous, electrically insulating, and is used in a range of electrical, mechanical and thermal applications. |
| Ultra High Temperature Machinable Ceramics | |
| For very high temperatures or where thermal conductivity or thermal shock is important, our machinable alkaline earth zirconium phosphate ceramics are recommended. MC-LD is a lower density material suitable for use where thermal shock resistance is important. MC-MD is a higher density material that is superior where better abrasion and wear resistance are desired. These materials can be used to 2700°F (1500°C), can be water quenched from 2550°F (1400°C), and have a very low thermal conductivity of just 1.0 W-mK°. |
