Product Description
Metallized alumina bodies with controlled joining or electrical interface areas for ceramic-to-metal assemblies.
Metallized alumina components use a process-specific metal layer on selected ceramic areas to support joining, plating or electrical connection.
The alumina body supplies electrical isolation while localized metal areas provide surfaces for joining or electrical connection, rather than making the entire ceramic body conductive.
Product Features
- Ceramic Electrical Isolation
- Controlled Metal Interface
- Brazing Preparation
- Drawing-Based Metallization
Typical Applications
- Electronic Packaging — Metallized ceramic package and support bodies: Supports defined joining and connection areas.
- Vacuum and Sensor Equipment — Ceramic-to-metal insulating assemblies: Provides a metallized ceramic interface for assembly review.
