Product Description Initially utilized in vacuum electronic devices, this technology has since found application across diverse sectors such as semiconductors, integrated circuits, aerospace, and more. Material selection plays a pivotal role in achieving optimal vacuum brazing outcomes. This discussion primarily focuses on three key material categories for ceramic-to-metal applications: Ceramic materials, notably Al2O3, are preferred for their high-temperature stability and compatible thermal expansion coefficients. Overcoming challenges such as non-wettability and thermal expansion differentials between ceramics and metals is achieved through meticulous soldering or brazing processes. Ceramics :>Al2O3 >BeO >BN >AlN >Metals Kovar alloy:>OFC (Oxygen-Free Copper) >Stainless steel >Mild steel Solders :>Ag (Silver)>Ag-Cu (Silver-Copper) >Cu (Copper) >Au-Cu (Gold-Copper) >Au-Ni (Gold-Nickel)hrough the innovation of Kovar Brazing Feedthrough Metallized Ceramic Components, the performance of welded joints is enhanced, enabling operation in elevated temperatures and hostile environments, thereby expanding the spectrum of application possibilities. By leveraging the ultimate fusion of ceramics and metals, this breakthrough technology heralds a new era of engineering excellence, poised to drive advancements across diverse industries.
