Company profile
Company profile:
The roots of ALUMINA SYSTEMS go back to the Siemens ceramic plant founded 1942 in Redwitz. ALUMINA Systems is producing ca. 400.000 p. a. ceramic-to-metal-joined integrated systems e.g. for thyristors (HVDC - High-Voltage Direct Current transmission), vacuum interruptors and x-ray systems.
Using primarily aluminum oxide ceramics and various non-ferrous metals, such as OF Cu (oxygen-free copper) or NiCo (nickel-cobalt), soft magnetic
alloys; NiFe (nickel iron) or stainless steel (1.4301), as connecting agents. As a material connecting technology, both passive and active brazing technique are used. With this, high-strength composites can be produced.They are permanently proof and vacuum-tight in the temperature range from –150 °C up to + 600 °C.
The core competencies in connection technology „Metal-ceramic composite“ enables ALUMINA SYSTEMS to open up other fields of applications. These are products such as vacuum feedthroughs (standard program), systems for CO2 lasers and ceramic batteries. Further experience exist in the bonding and shrinking of metal ceramic composites.
ALUMINA SYSTEMS stands as technology partner in the range of the metal-ceramic adding technology for electrical applications in:
• Vacuum systems
• Medical systems
• Laser systems
• Measuring and sensor engineering
• Energy technology
• 3D-printed of ceramic components
• X-ray systems
• FEA-added Product Development (FEA: Finite Element Analysis).
From single prototypes to serial production, we offer our customers the full range of customized solutions made by a innovative mid-sized company.
