Product Details
The 95% alumina metallized ceramic ring is designed for electrical, electronic, vacuum and ceramic-to-metal assembly applications that require reliable insulation together with a bondable metal interface.
Manufactured from 95% alumina ceramic, the ring provides good electrical insulation, mechanical strength, dimensional stability and resistance to high-temperature operating environments. Its large OD216 × ID40 × 20 mm structure makes it suitable for applications requiring a rigid ceramic insulating and supporting component.
The ceramic surface is metallized using a Mo/Mn metallization system with a layer thickness of 8 ± 1 μm, followed by 9 ± 1 μm electroplated nickel. This metallized structure provides a suitable surface for subsequent brazing, joining and ceramic-to-metal assembly processes while maintaining the insulating properties of the alumina ceramic substrate.
The nickel-plated metallized layer also helps provide a stable and consistent interface for further assembly operations. The combination of alumina ceramic, Mo/Mn metallization and nickel plating makes the component suitable for electrical insulation structures, vacuum components, high-voltage assemblies, electronic packaging and other applications requiring ceramic-to-metal integration.
INNOVA Supplies provides customized ceramic metallization services, including ceramic dimensions, metallized areas, metallization systems and plating specifications according to customer requirements.

Frequently Asked Questions
The ceramic substrate is made from 95% alumina ceramic, which provides good electrical insulation, mechanical strength, dimensional stability and resistance to high-temperature environments.
The ceramic ring uses a Mo/Mn metallization system. The Mo/Mn metallized layer has a thickness of 8 ± 1 μm, providing a metal-compatible surface for subsequent joining and assembly processes.
A 9 ± 1 μm electroplated nickel layer is applied over the Mo/Mn metallization. The nickel coating provides a stable metallic surface for subsequent brazing and ceramic-to-metal assembly while protecting the underlying metallized layer.
Metallized alumina ceramic rings are commonly used in ceramic-to-metal assemblies, electrical insulation structures, vacuum components, high-voltage equipment, electronic packaging and other applications requiring both ceramic insulation and a bondable metal interface.
The Mo/Mn metallization with nickel plating provides a suitable surface for subsequent ceramic-to-metal brazing and joining processes. Actual brazing materials, temperatures and process conditions should be selected according to the mating metal and assembly requirements.
Yes. INNOVA Supplies provides customized ceramic metallization services, including ceramic dimensions, metallized areas, metallization patterns, Mo/Mn metallization specifications and plating requirements according to customer drawings and application needs.
