What is Ceramic to Metal Brazing?
Ceramic to Metal Brazing is a specialized joining technique that bonds ceramic components to metal parts, offering unmatched durability, biocompatibility, and resistance to extreme environments. Widely used in medical devices, laser assemblies, microwave tubes, and electrical feedthroughs, this method provides high joint strength for vacuum, high voltage, and high-pressure conditions. With growing demand in aerospace, defense, and biomedical sectors, this technology is becoming essential for advanced engineering systems.
Key Materials & Brazing Processes
Brazing ceramics like Polycrystalline Alumina (94%-99%), Sapphire, BeO, Si3N4, AlN, and ZrO2 to metals such as Kovar, Molybdenum, Titanium, Inconel, and Nickel Alloys requires precision. Common brazing methods include:
- Vacuum Brazing
- Active Metal Brazing
- Hydrogen Brazing
- Reactive Air Brazing
The choice of braze alloy—gold, silver, copper or their alloys—depends on application-specific requirements for conductivity, strength, and corrosion resistance. Pre-metallization through Mo/Mn thick film or sputtering thin film enhances bond quality and reliability.
Custom Hermetic Products for High-Reliability Systems
When creating mission-critical systems, ensuring a hermetic seal is paramount. Solutions such as hermetic connectors, glass to metal seals, ceramic to metal seals, and hermetic headers are all vital components in devices requiring long-term performance in harsh environments. Whether for implantable medical devices or satellite communication modules, these hermetic products protect sensitive electronics from moisture, pressure shifts, and chemical exposure.
