We apply thin metallization layers to ceramic parts like alumina, zirconia, and silicon carbide to promote wetting and bonding with brazing filler metals. Common metallization materials include:
- Nickel – Diffuses well with silver-based braze alloys
- Copper – Excellent wettability but requires plating with gold or nickel
- Kovar or Invar – Alloys match ceramics’ CTEs to minimize residual stress
- Tungsten or Moly-Manganese – Active metal brazes readily bond to these layers
Proper surface preparation ensures strong adhesion of the metallization layer to the ceramic. Our engineering experts work with you to select the best metallization materials and processes to achieve reliable, high-strength brazed joints, even with challenging geometries.
