Company profile

Company profile:

ALUMINA SYSTEMS GmbH manufactures vacuum-tight ceramic-to-metal joined assemblies for a wide variety of applications. Its specialized expertise lies in the joining technology of ceramics and metals. The dynamically growing company is repeatedly recognized for its innovative products: ALUMINA SYSTEMS has repeatedly received the title of Top Innovator, the Innovation Life Award from Bayern Innovativ, and the Best Components Award from the trade journal „Ceramic Application“. ALUMINA SYSTEMS GmbH traces its roots back to the ceramics division of the Siemens Group. The company has been manufacturing at its Redwitz/R. site since 1970.

CERAMIC-METAL COMPONENTS FOR USE IN HIGH-TECH APPLICATIONS
Vacuum-tight metal-to-ceramic joined assemblies – manufactured from the high-performance material aluminum oxide and a metallic joining partner – are the core business of ALUMINA SYSTEMS GmbH. These components are used wherever switching extremely high energies is required, e.g., in energy, laser, X-ray, plasma, medical, and accelerator technology. A major advantage of technical ceramics is their high electrical insulation, even at high tem-peratures. Application areas include, for example, sensors in ship engines (thin-wire bonding), precursor gas distribution rings in wafer coating (PE-ALD), or small thrusters for satellites. Ceramic-to-metal brazed components are essential for making these applications possible. In addition to standard products such as ceramic feedthroughs, vacuum interruptor tubes, and vacuum insulators, the demand for custo-
mized, high-end applications is constantly increasing. At ALUMINA SYSTEMS, the design of these components is analyzed for mechanical and thermal stresses using the finite element
analysis (FEA). The optimal design for the application can then be
selected before the first prototypes are produced.
