What Alumina Systems GmbH does

Alumina Systems GmbH is a German specialty manufacturer of vacuum-tight ceramic-to-metal composite components, founded in 1984 and headquartered at a single manufacturing site in Redwitz an der Rodach, Bavaria, with a workforce of over 100 employees. The company produces custom-engineered components using aluminum oxide (Al₂O₃ 99.9%) and zirconium oxide ceramics joined to metals through proprietary metallization (MoMn/WMn paste fired at ~1,400°C), active and passive brazing (AgCu eutectic and Ti/Zr/Hf active solders), in-house chemical and galvanic nickel plating, ENIG gold plating, glass soldering, and antistatic conductive coatings. It has additionally adopted Lithography-based Ceramic Manufacturing (LCM) for 3D-printed dense ceramic geometries that are unachievable through injection molding, pressing, or extrusion. Its product portfolio is organized into 12 industrial divisions — 3D Systems, Chip Systems, Energy Systems, Oil-Gas Systems, Laser Systems, Plasma Systems, Sensor Systems, Space Systems, Vacuum Systems, X-Ray Systems, HVDC Systems, and Mechanic Systems — addressing semiconductor fabrication equipment, power electronics and HVDC transmission, sensors for marine diesel engines, satellite and propulsion subsystems, coating and vacuum chambers, X-ray tubes and detectors, and oil/gas exploration components.

The company operates a custom project-based B2B manufacturing model with no public pricing or catalog, delivering from prototype through series production with multi-year contracts and direct technical consultation. Go-to-market is exclusively direct enterprise field sales, supported by SEO-optimized technical content on alumina.systems, trade fair participation (Ceramitec, SEMICON), customer success stories, and a small organic social presence (Facebook, Instagram). All revenue is hardware sales; the customer base spans industrial enterprises across semiconductor, power/energy, sensor, space, vacuum, oil/gas, medical, and X-ray/security verticals, with documented multi-decade supply relationships including a 40-year zero-return record in power-industry thyristor and diode housings. Alumina Systems is owned by SWACRIT Systems (strategic operating parent) and is led by authorized managing director Dr.-Ing. Holger Wampers. The company holds the T100 Top 100 German Innovators award (2023), a 2020 Research Seal, and a 2023 ILAward, and maintains helium leak-rate performance of 10⁻⁸ to 10⁻¹¹ mbar L/s with brazed bond strengths exceeding 200 MPa.

Core offering

Alumina Systems GmbH manufactures custom vacuum-tight ceramic and ceramic-metal composite components from aluminum oxide (Al2O3 99.9%) and zirconium oxide for industrial customers. The company combines proprietary metallization, passive and active brazing, in-house nickel/gold plating, glass soldering, and LCM-based ceramic 3D printing to deliver hermetic components, feedthroughs, sensor housings, and insulators. Production is organized into 12 application-specific divisions (3D, Chip, Energy, HVDC, Laser, Oil-Gas, Plasma, Sensor, Space, Vacuum, X-Ray, plus integrated systems) and runs from prototype through series production at the Redwitz/R., Germany facility.

Product overview

Alumina Systems GmbH offers a comprehensive portfolio of vacuum-tight ceramic-to-metal integrated systems, organized into 12 specialized product divisions. The core offering combines aluminum oxide (Al₂O₃) and zirconium oxide ceramics with metallic components through advanced manufacturing processes including brazing, soldering, and 3D printing. Key product lines include: 3D Systems (L CM-based ceramic 3D printing), Chip Systems (semiconductor components), Energy Systems (power electronics), HVDC Systems (high-voltage transmission), Laser Systems, Oil-Gas Systems, Plasma Systems, Sensor Systems, Space Systems, Vacuum Systems, and X-Ray Systems. The company serves demanding applications in extreme conditions including high temperatures, aggressive chemicals, high pressures, and vacuum environments, with a notable track record of zero thyristor/diode housing returns over 40 years in the power industry.
