Can be used to shape fillets and to bridge large gaps. Fillets may be used for bridging large gaps or for distributing stresses in the assembly. Tendency to liquation. Light yellow color. Maximum service temperature 204 °C (intermittently 316 °C). Gap 0.1–0.25 mm. Cadmium-free alternative is BAg-24. 15.5: 15.5: 50: 3: 16: Ag 44 Cu 27 Zn 13 ...
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
Close-up of top seal, opening notch, and internal reclosable strip. Resealable packaging is any type of packaging that allows the consumer or user to reseal or reclose the packaging. Often packaging needs to be resealed in order to maintain product freshness or prevent spillage. Reusable packaging allows for multiple uses which can help reduce ...
Brazing practice. Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work
Adjustable-length seals can fit many applications from securing the neck of a bag or mail sack to sealing chemical drums, first aid kits, and fire extinguishers. They have an adjustable length much like a cable seal but offer a much higher security level and an audit trail due to sequential numbering and the ability on some seals to be bar ...
Seams, creases, access points, and heat seals are critical to end-use performance. For example, the glass of a bottle may have an effective total barrier, but the screw cap closure and the closure liner might not. Performance verification and validation of complete containers, structures, or irregular objects is often recommended.
Ground glass surfaces are shown with gray shading. By assembling them in the direction of the arrows, they can be joined. The conically tapered ground glass joints typically have a 1:10 taper and are often labeled with a symbol S T, consisting of a capital T overlaid on a capital S, meaning "standard taper". This symbol is followed by a number ...
Glass frit bonding, also referred to as glass soldering or seal glass bonding, describes a wafer bonding technique with an intermediate glass layer. It is a widely used encapsulation technology for surface micro-machined structures , e.g., accelerometers or gyroscopes . [ 1 ]
