Suitable for brazing ceramics to metals as well as other non-metallic components without the need for prior metallization of the contact surface.
Available Forms
Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste.
Characteristics
Suitable for use in all vacuum brazing applications as well as under partial pressure of argon gas. Brazing of active alloys under protective nitrogen atmosphere is not recommended. It is important to maintain a high purity, oxygen-free environment; any oxidation of reactive elements will limit alloy wettability across the non-metallic surface. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for silver-base alloys ranges between 0-0.002 in (0-0.05 mm).
Properties
The properties of a brazed joint are dependent upon the base metal, joint design and brazing technique. This alloy in particular is ductile and will exhibit exceptional corrosion resistance due to the high silver content.
