Ceramic – Metal Components
High-precision ceramic-to-metal brazed assemblies for demanding environments
AVELION is an ideal partner for the design and manufacture of brazed assemblies, from prototype development to series production. AVELION custom-manufactures components in which dissimilar materials are required to meet specific technical requirements. Ceramics (aluminium oxide, sapphire, zircon, etc.) and metals (beryllium, titanium, copper, ferrous and non-ferrous alloys, etc.) are the core materials used across manufacturing processes such as forming, machining, grinding, surface treatment, vacuum and controlled-atmosphere brazing, welding, and bonding for demanding applications in electron microscopy, defense, nuclear, and subsea environments.
Ceramic-to-Metal Brazed Mechanical Components for Electron Microscope
- High dimensional accuracy
- Ultra-clean components with controlled deburring
- Expertise in brazing dissimilar materials
- Compatibility with UHV environments
Ceramic-to-metal brazed mechanical components for electron microscopes are critical elements that ensure precise positioning, mechanical stability, and vacuum integrity within the instrument. High dimensional accuracy is essential to guarantee proper alignment of electron-optical elements and to maintain imaging resolution.
Manufacturing processes are optimized to achieve exceptional cleanliness, controlled deburring, and surface quality, minimizing particle generation and contamination risks. The controlled brazing of dissimilar materials — typically ceramics and metallic alloys — ensures robust mechanical joints while accommodating differences in thermal expansion and mechanical behavior.
These components are specifically developed to meet the stringent mechanical, vacuum, and cleanliness requirements of electron microscopy applications.
Ceramic and Metal Feedthrough
- Reliable electrical transmission across sealed vacuum or pressure boundaries
- Made from dissimilar materials and resistant in harsh environments
- Feedthroughs designed and constructed for civil and military applications
Ceramic-to-metal feedthroughs are critical components used to transfer electrical signals or power across a vacuum or pressure boundary while maintaining electrical insulation and environmental sealing. They are designed to ensure reliable electrical performance while preserving vacuum integrity and mechanical robustness.
These feedthroughs combine ceramics and metallic parts through controlled joining processes, allowing the use of dissimilar materials optimized for thermal, electrical, and mechanical performance. Their robust design makes them suitable for operation in harsh environments, including applications subject to severe thermal, mechanical, and electrical stresses.
All designs are developed to meet the reliability and qualification requirements of civil and military applications.
