It is commonly used for electronics, telecommunications, and aerospace components, such as hermetic seals for devices like vacuum tubes and transistors, telecommunications equipment, and turbine blades. Its ability to nearly match the coefficient of thermal expansion of glass enables airtight sealing, preventing moisture or contaminants from damaging sensitive electronic
