Product Description
Metallized ceramic rings, tubes and bodies prepared for drawing-based ceramic-to-metal brazing assemblies.
Brazing ceramic components are ceramic bodies with interface areas prepared for joining to a compatible metal counterpart.
A suitable metal interface enables a braze alloy to wet the ceramic joining area, combining a ceramic insulating body with a metal connection.
Product Features
- Brazing Interface
- Electrical Insulation
- Ceramic-to-metal interface design
- Assembly-Specific Geometry
Typical Applications
- Electrical Equipment — Insulating ceramic-to-metal assemblies: Supports a controlled brazing interface in the submitted design.
- Vacuum and Process Equipment — Sealed ceramic-metal components: Provides a prepared ceramic body for joining evaluation.
