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.
