Insulating Sitall Microcrystal Glass Macor Ceramic Machining Cover Lid
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. Glass-ceramics with high mechanical strength, glass-ceramics, machinable glass-ceramics and bioactive glass-ceramics 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.
