Product Feature:
1. High use temperature
2. Machinable by ordinary machine tools
3. Excellent electrical insulator
4. Excellent thermal insulator
5. Dimensionally stable
With Machinable Glass Ceramic (MGC), fabrication is fast - because it can be machined into complicated shapes and precision parts with ordinary metal working tools, quickly and inexpensively, and it requires no post firing after machining. That means no frustrating delays, no expensive hardware, no post fabrication shrinkage, and no costly diamond tools to meet specifications.
Property of Machinable Glass Ceramics
1. MGC can be machined with ordinary metal working tools and there is not need for post firing - meaning fast turnaround
2. It has a continuous use temperature of 800 C and the the max. Is up to 1000 C.
3. MGC has low thermal conductivity, it is a exellent temperature insulator.
4. MGC has no porosity and will not outgas when properly baked. It is widely used in ultra high vacuum applications.
5. MGC has high electric insulativity and it is used extensively throughout the semiconductor and electronic industries.
6. MGC has radiation resistant and plays a key role in nuclear applications and nuclear-related research and development.
7. MGC is unlike high temperature plastics, it will not creep or deform.
8. MGC can be thick or thin film metallized, brazed, epoxy and frit bonded.
