Machinable Glass Ceramic

Machinable ceramics not only exhibit excellent processing capabilities, vacuum compatibility, electrical insulation, high-temperature resistance, and chemical corrosion resistance, but they also stand out for their ability to be machined using conventional metalworking techniques. This makes them an ideal choice for low-volume, high-mix, and confidential components.

Material Characteristics

High strength with lightweight properties
Rich and varied colors
Excellent weather resistance and durability
Superior high-temperature electrical insulation performance
Resistant to aging and deformation
Excellent acid and alkali corrosion resistance

Material Applications

Machinable ceramics are suitable for a wide range of applications, including:

Automotive
Military and defense
Aerospace
Precision instruments
Medical equipment
Electric vacuum devices
Electron beam lithography systems
Textile machinery
Sensors
Mass spectrometers and energy spectrometers

For thin-walled coil bobbins, insulating supports for precision instruments, and high-accuracy components with complex shapes, machinable ceramics are particularly well-suited. They can be machined into virtually any desired form.
