Glass Metal - borosilicate - quartz

Glass-to-Metal

Solcera glass-to-metal seals are designed, manufactured and tested at our facility in Moissy-Cramayel (formerly known as VERMETAL) located 30 minutes from Paris.

Our technical experts work in partnership with our customers very early in the product development process in order to provide the most suitable solution in terms of design and materials for glass-to-metal sealing technologies.

The main markets served for seals are aircraft, aerospace, defense, nuclear and physical research. The glass-to-metal assemblies meet the very demanding needs of electrical insulation, hermeticity, high-vacuum HV and ultra-high vacuum UHV reliability or high-pressure capability.

Solcera offers material combinations including

Glasses: borosilicate, electronic, quartz
Metals: FeNiCo, stainless steel, copper, molybdenum, tungsten
Sealing technologies: glassblowing, high-frequency, oven furnace glass sealing technology
