Active alloy. Can be used for brazing ceramics, metal-ceramics, graphite, diamond, corundum, sapphire, ruby. Needs at least 850 °C for wetting ceramics, higher temperatures improve wetting. For use under argon or vacuum, in vacuum silver may evaporate above 900 °C. 19.5: 72.5: 3: In 5: Ag 96 Ti 4: active 970 [98] – BrazeTec CB2. Active alloy.
Undercut studs have a shank equal to the pitch diameter of the screw thread. Undercut studs are designed to better distribute axial stresses. In a full-bodied stud the stresses are greater in the threads than in the shank. [5] Undercut studs (rolled thread) are also stronger because the metal is "rolled" up to the major diameter, not removed.
The center metal is often copper; its role is to act as a carrier for the alloy, to absorb mechanical stresses due to e.g. differential thermal expansion of dissimilar materials (e.g. a carbide tip and a steel holder), and to act as a diffusion barrier (e.g. to stop diffusion of aluminum from aluminum bronze to steel when brazing these two).

ASTM A354 is an ASTM International standard that defines chemical and mechanical properties for alloy steel bolts, screws, studs, and other externally threaded fasteners.It is officially titled: Standard Specification for Quenched and Tempered Alloy Steel Bolts, Studs, and Other Externally Threaded Fasteners.
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
