Company profile

Being a former ceramics and porcelain factory of Siemens, LAPP Insulators Alumina has over 40 years of experience with components made from ceramic materials. Lapp Insulators Alumina GmbH manufactures annually about 300 000 metal-ceramic composites such as thyristors and vacuum interrupters for use in high-vacuum technology (HVDC - High-voltage direct current transmission, vacuum technology). 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-logical connecting technology, both passive and active brazing technique are used. With this, high-strength composites can be produced which are permanently proof and vacuum-tight in the temperature range from -150 °C up to + 500 °C. The core competencies in connection technology "Metal-ceramic composite" enables LAPP Insulators Alumina to open up other fields of application. These are in products such as vacuum feedthroughs (standard program), for CO2 lasers and printing of circuit boards. Further experience exist in the bonding and shrinking of metal ceramic composites. LAPP Insulators Alumina stands as technology partner in the range of the metal-ceramic adding technology for electrical applications into the fields of:
• Vacuum technology
• Medical technology
• Laser technology
• Measuring and sensor engineering
• Energy technology
• 3D-printed ceramics
• FEA – Analysis (Finite Element Analysis)
From single prototypes to series with thousand pieces, we offer our customers a flexible range of production of a mid-sized company.
