Properties / Main use conditions
Its French name is "DILVER ®" because this alloy has same expansion as glass. It is used for jointing glass/metal, and ceramics/metal. It has a rate of thermal expansion extremely low, between -100 and +450°C.
Sealing for electronical tubes or X-rays with high tightness vacuum ; integrated circuit supports.
