Product Description
Macor mica machinable Ceramics:
Microcrystalline glass ceramics, also known as machinable ceramics, are mica glass-ceramics with synthetic mica as the main crystalline phase, and are ceramic
materials that can be machined. Microcrystalline glass ceramics have excellent processing properties, vacuum properties,
electrical insulation properties, and high temperature and chemical
resistance.
Macor ceramics have excellent processing properties, vacuum properties,
electrical insulation properties, and high temperature and chemical
resistance. Glass-ceramics with high mechanical strength of
glass-ceramics, machinable glass-ceramics and bioactive glass-ceramics.
Application industry:
Machinery, electronic, limitary, aerospace etc.
Specific application: Machined equipment high temperature insulated
parts, electronic equipment high temperature insulated parts.
Macor ceramics are particularly suitable for automotive, military, aerospace,
precision instruments, medical equipment, electric vacuum devices,
electron beam exposure machines, textile machinery, sensors, mass
spectrometers and energy spectrometers. For some thin-walled coil
bobbins, precision instrumented insulation brackets, and
complex-shaped devices with high precision requirements, glass-ceramics are more suitable, and they can be processed into any shape.
