Company profile

LAPP Insulators Alumina produces semiconductor housings for high performance electronics. A key technology used in this process is the vacuum-tight brazing of aluminum oxide ceramics with metals, such as ultrapure copper or various Ni-Fe alloys and stainless steel. LAPP Insulators Alumina has more than 30 years of experience. For housings LAPP is worldwide quality leader with high power throughput in excess > 1 GW. Approx. 300,000 housings are produced every year in Redwitz. As manufacturer of metal-ceramic joined parts LAPP produces components for vacuum, plasma, laser, accelerator and energy technology. LAPP Insulators Alumina uses FEM-supported component for designing optimized parts. So development time and cost can be reduced. For vacuum technology LAPP offers a commodity program of power feedthroughs and vacuum insulators
