Design Features

Machinable ceramic components (aka: macor ceramic parts) are a unique engineering material specifically designed to meet the needs of industrial applications with high precision and complex shapes. The following are the design features and main application areas of these ceramic components:


Easy to process

Macor machinable ceramics can be drilled, milled, ground and polished using conventional metalworking tools, without the need for dedicated ceramic processing equipment. This reduces the cost and time of manufacturing complex components.


High temperature stability

The ability to maintain mechanical stability and dimensional accuracy at temperatures up to 800°C makes it suitable for high temperature applications.


Excellent electrical insulation

The extremely high electrical insulation strength (30 KV/mm) and volume resistivity (10^16 Ω.cm) make it an ideal material for electronic and high voltage applications.


Thermal management performance

The low thermal conductivity (1.71 W/(m·K)) and good thermal shock stability (△T 200℃) make it suitable for environments that require rapid temperature changes.


Chemical stability

It does not absorb water and has zero permeability, indicating that it can maintain its performance in a variety of chemical environments.


Application Areas

Aerospace

Used to make insulators and brackets in thermal management systems of spacecraft, and components for handling extreme temperatures.


Semiconductor Manufacturing

Used as handling arms or support structures in semiconductor manufacturing equipment, its low dust characteristics are particularly important for maintaining clean room environments.


Laboratory Equipment

In laboratory analysis and testing equipment, macor ceramics are used to make precision parts because they can be accurately machined into complex shapes.


Electrical Insulation Applications

In power and high-voltage equipment, it is used to make insulators to prevent arcing and current leakage.


Thermal Management Applications

Used as heat dissipation components in electronic equipment, especially in temperature-sensitive or highly insulated equipment.


Macor machinable ceramic structures have shown great application value in aerospace, semiconductor manufacturing and electrical insulation with their high-precision machining capabilities and superior thermal and electrical properties. These characteristics make it an indispensable material in modern high-tech industries, especially in high-end applications with strict material performance requirements. Its easy machinability further enhances its appeal in the design and manufacture of complex industrial components, providing an economical and efficient solution.
