A must-have for scientific instruments that isolate the vacuum side from the atmospheric side! It features high airtightness and stable productivity.
Our company provides "metallized brazed products" using our own alumina, tailored to your specifications. By using the "molybdenum-manganese metallization method" on our alumina, we enable bonding with dissimilar metals. Molybdenum-manganese metallization aims to improve the wettability of the filler material and to form electrical circuits, characterized by high airtightness and stable productivity. Additionally, we can also offer "Au (gold) metallization" aimed at preventing charge-up, and "Ag (silver) metallization" for the formation of electrical circuits. Regarding bonding methods, we support "active brazing" using silver brazing with added active metals, and we can also perform "glass bonding" that does not require metallization. 【Features】 ■ Ceramic type: Alumina (no supplied materials allowed) ■ Bonding metals: Primarily Kovar, along with Mo, Cu-W, etc. ■ Airtightness: Guaranteed to be below 1×10^-11 Pa·m3/s (in the case of Kovar + silver brazing combination) ■ Bonding materials: Silver brazing, gold brazing, active brazing, glass bonding *For more details, please refer to the PDF document or feel free to contact us.
