Ceramic-metal composite for the highest demands
The demands on modern technologies are constantly growing: higher temperatures, more aggressive environments, and increasing power densities. Conventional materials often reach their limits. The solution is ceramic-metal composites, which combine the best properties of both worlds.
Alumina Systems has been developing and producing ceramic-metallic components specifically designed for extreme loads for many years. Our components are characterized by vacuum-tight feedthroughs, absolute gas tightness, and exceptional mechanical stability.
Our expertise: permanently joining metal and ceramic
Joining ceramic and metal is technically challenging, as both materials have very different coefficients of expansion. Alumina Systems has mastered this process for decades – particularly through brazing and other innovative joining techniques.
The result is ceramic-metal components that:
- withstand high thermal cycles,
- are vacuum-tight,
- are electrically insulating, and at the same time, are mechanically resilient.
Typical applications of ceramic-metallic components
Our solutions are used in a wide variety of industries:
- Semiconductor industry: Vacuum-tight components for production facilities.
- Sensor technology: Hermetic feedthroughs for pressure and gas sensors.
- Energy and power electronics: Ceramic insulators for high-voltage switches and power modules.
- Vacuum technology: Components for coating systems, fusion reactors, and accelerators.
- Medical technology: High-purity, biocompatible components for implants and analytical devices.
- Aerospace technology: Ceramic-metal housings for satellites and propulsion systems.
- Oil and gas industry: High-pressure-resistant seals and insulators.
Each of these sectors benefits from our experience in developing high-performance components precisely tailored to their respective applications.
