Mascera is a professional supplier for technical ceramic parts, we provide custom manufacturing for alumina ceramics, zirconia ceramics, boron nitride ceramics, silicon nitride ceramics, silicon carbide ceramics, aluminum nitride ceramics and machinable glass ceramics.

Machinable glass ceramics offered by Mascera have very good machining performance. Machining processes of turing, milling, grinding, drilling or tapping could be made easily with ordinary metal working tools. The machining accuracy can reach as precision as micron level and the surface could be very smooth. The good machinability of machinable glass ceramics will greatly save production time and cost for urgent prototyping work of complicated parts.

Product detail

Mascera offers machinable glass ceramics with excellent machining performance. These ceramics can be easily machined using standard metal working tools for turning, milling, grinding, drilling, or tapping processes. The machining accuracy can reach micron-level precision, resulting in smooth surfaces. The outstanding machinability of these glass ceramics significantly saves production time and costs, particularly for urgent prototyping work involving complex parts.

Machinable glass ceramics exhibit both electrical and thermal insulation properties, with a thermal conductivity similar to that of zirconia ceramics. They possess exceptional thermal shock resistance, remaining intact when rapidly cooled from 800°C to 0°C. These ceramics can withstand a maximum working temperature of 1000°C under no-load conditions. Their thermal expansion coefficient matches well with most metals and sealing glasses. Thanks to their high strength, machinable glass ceramics do not creep or deform at high temperatures.

Mascera provides machinable glass ceramics for various applications in mechanical, chemical, thermal, and electrical fields. They are widely used in aviation, aerospace, electronic substrates, high-temperature insulation frameworks, ion coating, vacuum coating, ion microscopes, ion accelerators, lasers, and medical equipment, among others. We offer high-precision machining services for machinable glass ceramic parts. Alternatively, we also have stocked ceramic rods and plates available for fast delivery if you prefer to machine them yourself.


Key properties of machinable glass ceramics:

1. Excellent machinability, allowing for easy shaping and machining processes.

2. Good electrical insulation properties, preventing the flow of electric current.

3. High resistance to elevated temperatures, enabling use in hot environments.

4. Low thermal conductivity, minimizing heat transfer.

5. Exceptional thermal shock resistance, withstanding rapid temperature changes without fracturing.

6. Good resistance to acid and alkali substances, ensuring chemical stability.

7. Thermal expansion coefficient matching that of most metals and sealing glasses, reducing the risk of thermal stress.

8. Zero porosity, resulting in a material without any air leakage.

Typical applications of machinable glass ceramic

  • High voltage insulators

  • Precision coil formers

  • Spacers, cavities and reflectors in laser assemblies

  • Insulating coil support for vacuum feed-throughs

  • Retaining rings for hinge points, windows and doors of space shuttle

  • Nozzles for welding equipment
