Materials can be freely selected according to the purpose! Various metal tubes can be converted into glass tubes!
Our "Glass-Metal Joining" technology enables the direct bonding of Kovar metal and Kovar glass, which have matching coefficients of thermal expansion. By using Kovar metal, various metal tubes can be converted into glass tubes. In development cases, we have implemented stepwise joint bonding using intermediate glass, not just Kovar glass. Materials can be freely selected according to applications, ranging from Pyrex glass to quartz glass and soda-lime glass, which have significantly different coefficients of thermal expansion. 【Features】 ■ Kovar metal and Kovar glass with matching coefficients of thermal expansion can be directly bonded. ■ Various metal tubes can be converted into glass tubes through Kovar metal. ■ Environmental performance of the joint - Heat resistance temperature: -196℃ to 400℃ - Leakage rate: 1×10^-7 Pa·m3/sec (He) or less *For more details, please refer to the PDF document or feel free to contact us.
