Product Description

Product Description

Thermal Shock Resistance Macor Electrical Insulator White Machinable Glass Ceramic Structural Part

These custom-made Macor electrical insulators are complex-shape structural components precision CNC machined from premium grade machinable glass ceramic blanks. Featuring multi-step raised profiles, positioning notches and central mounting holes, these white Macor structural parts are engineered for high precision mechanical assembly, electrical isolation, thermal barrier and positioning duties.

White Machinable Glass Ceramic Structural Part

Unlike traditional alumina or zirconia ceramics which require high temperature sintering followed by expensive diamond grinding, Macor glass ceramic can be directly machined with standard carbide cutting tools. Intricate geometries such as step-down profiles, positioning lugs, notches, counter-sinks and mounting holes can be milled accurately in one process. No secondary sintering after CNC machining eliminates dimensional shrinkage, ensuring precise hole-position accuracy, flatness and tight tolerance control for these complex multi-feature insulators.

Main Application Scenarios
Laser equipment insulating support blocks and positioning structural insulators.
Vacuum chamber internal isolation fixtures and mounting components.
High voltage electrical modules, power supply insulating structural parts.
Laboratory high temperature test jigs, positioning bases and sample holders.
Semiconductor and optoelectronic processing equipment components.

Machinable Glass Ceramic Features

The high performance machinable glass ceramic features zero water absorption rate and low apparent porosity. Its moderate hardness supports CNC turning, milling, drilling, slotting and chamfering. Custom non-standard diameter, thickness, stepped surfaces and hole layouts are available with no high cost mould. With dependable mechanical strength, heat resistance and insulating property, the discs are widely applied in heating equipment, precision testing instruments, semiconductor jigs and laboratory high temperature fixtures.
Physical feature. Mohs hardness ranges 4 to 5. Edges stay smooth after turning and drilling with little edge chipping. The density is 2.6g/cm³ with waterproof dense texture.
Thermal resistance. The average thermal expansion coefficient equals 72×10^-7/℃ from minus 50℃ to 200℃ for excellent thermal shock resistance. 
Mechanical property. Flexural strength exceeds 108MPa and compression strength exceeds 508MPa to endure component pressing, bolt fastening and machine vibration loads.
Electrical insulation. The permittivity ranges 6 to 7 alongside low dielectric loss for stable high temperature insulation.
