Custom sizes, thicknesses, holes, slots, chamfers and surface finishes are available based on drawings or samples.
Application Industries:
Power electronics, high-voltage equipment, semiconductor modules, new energy systems, EV controllers, charging modules, heating equipment, sensors, transformers and ceramic substrate and plate applications.
Lead Time:
Lead time depends on material grade, part size, structure, tolerance requirements, machining complexity and order quantity. Please send drawings, samples or application details for evaluation.
CERAMPRO ceramic insulation plates are made from high-purity alumina ceramic, with Al₂O₃ content available from 96% to 99.8% according to application requirements. These ceramic plates are designed for electrical insulation, heat resistance, structural support and isolation protection in high-temperature, high-voltage and power electronic applications.
This product is mainly made from alumina ceramic. Alumina ceramic offers a practical balance of electrical insulation, mechanical strength, high-temperature resistance and cost control, making it widely used for electrical insulation plates, support plates, thermal barriers and structural ceramic parts.
For applications that require better thermal conductivity, machinability, thermal shock resistance or wear performance, CERAMPRO can also evaluate alternative materials such as aluminum nitride, boron nitride or ZTA ceramic. Material selection should be based on working temperature, voltage level, installation method, part structure and actual operating environment.
Ceramic insulation plates are suitable for applications where metal or plastic materials may not provide enough insulation, heat resistance, corrosion resistance or dimensional stability. They can work as both insulating barriers and structural support parts.
CERAMPRO focuses on custom precision ceramic components and can provide ceramic insulation plates based on customer drawings, samples or application requirements. We do not only supply ceramic materials; we also help customers evaluate suitable ceramic solutions according to working conditions, part structure and machining requirements.

A ceramic insulation plate is mainly used for electrical insulation, high-temperature resistance, structural support and isolation protection. It is commonly used in power electronics, high-voltage equipment, semiconductor modules, new energy control systems and heating equipment.
Alumina ceramic is commonly used because it provides a good balance of electrical insulation, mechanical strength, high-temperature resistance and cost performance for most insulation and support applications.
Yes. CERAMPRO can customize size, thickness, hole patterns, slots, chamfers, surface finish and special-shaped structures based on customer drawings or samples.
Yes. Alumina ceramic has good electrical insulation performance and is commonly used in high-voltage equipment, power electronic modules and electrical isolation structures.
Yes. Ceramic insulation plates can be used in semiconductor modules, power modules, mounting structures and insulation support parts. The final material and dimensions should be evaluated according to the actual working environment.
Yes. We can machine holes, slots, steps, chamfers, outer profiles and other custom structures according to customer drawings.
Alumina is more suitable for general insulation, heat resistance and structural support applications. Aluminum nitride is more suitable when both electrical insulation and higher thermal conductivity are required, such as heat dissipation and power module applications.
Ceramic materials have high hardness and good wear resistance, but their impact toughness is lower than metals. Sharp corners, overly thin structures and strong impact should be avoided during design and installation.
We recommend providing drawings, material requirements, dimensions, tolerance, thickness, quantity, working temperature, voltage requirements, application environment and inspection requirements. More complete information helps us provide a more accurate quotation and process evaluation.
Yes. CERAMPRO can support prototype, small-batch and batch customization for ceramic insulation plates, as well as other electronic ceramic components.
