custom insulator microcrystalline ceramic machinable structural parts
Product Description
Macor mica machinable Ceramics:
A. corrosion resistant
because it is completely composed of inorganic materials, so there is no aging and no deformation, very stable to various organic solvents and good acid and alkali corrosion resistance.
B. Excellent weather resistance and durability
The acid-resistant and alkali-resistant glass-ceramics are superior to granite and marble, and are inherently inorganic materials. Even when exposed to wind and rain and polluted air, they will not cause deterioration, fading, and inferior strength.
C. High intensity and light weight
Glass-ceramics are harder than natural stone and are not easily damaged. The thickness of the material can be matched with the construction method, which is in line with the light and sturdy mainstream of modern buildings.

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.
