Custom Metallized Alumina Ceramic Ring For Vacuum Seals
1. Product Superiority
- Exceptional Solderability & Adhesion: Our proprietary Mo-Mn metallization process ensures a bond strength exceeding 150 MPa. This solves the common issue of metal layer peeling during high-temperature brazing or subsequent soldering processes.
- Micron-Level Dimensional Precision: Utilizing advanced centerless grinding and CNC machining, we maintain tolerances as tight as ±0.05mm. This solves the “fitment and alignment” problems in automated micro-assembly lines.
- Guaranteed Hermeticity: Each ceramic ring is designed for a helium leak rate of <1×10⁻⁹ Pa·m³/s. This prevents vacuum degradation in sensitive electronic packages, extending the operational life of sensors and laser modules.

2. Product Description
In the realm of micro-electronics and precision sensors, the smallest component often bears the greatest responsibility. A single failure in a ceramic-to-metal seal can compromise an entire aerospace system or medical device. For engineers searching for uncompromising reliability in miniature components, our Metallized Alumina Ceramic Rings provide the perfect intersection of high dielectric strength and robust brazing integrity.
Engineered from high-purity 95% or 99% Alumina, these rings feature a precision-applied metallization layer (Mo-Mn) that is co-fired for maximum adhesion. These rings are the preferred choice for RF connectors, laser diode housings, and high-pressure sensor feedthroughs. By matching the Coefficient of Thermal Expansion (CTE) with common metal alloys like Kovar or Stainless Steel, we eliminate stress-induced cracking, ensuring a hermetic seal that lasts.
We don’t just supply parts; we enable high-tech integration. Our integrated manufacturing process—from ceramic forming to final plating—ensures consistent quality across every batch, whether you need 100 or 100,000 pieces.
