Gold Braze 7008™
Gold Braze 7008™ Technical Data
Uses
Gold Braze 7008 can be used on any of the common ferrous, non-ferrous, and super alloys. Typical applications include brazing of electron tubes, vacuum tubes, wave guides in electronic industry. In aerospace industry, Gold Braze 7008 can be used in brazing of fuel line assemblies and aero-engine components.
Brazing Characteristics
Gold Braze 7008 is a high strength, high ductility alloy that exhibits higher corrosion and oxidation resistance in comparison to standard gold-copper alloys. The addition of nickel render this alloy somewhat more sluggish in flow characteristics but improves wettability on ferrous alloys.
Properties of Brazed Joints
The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design and brazing technique. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for gold base alloys fall within 0.000in – 0.002in (0.00mm-0.05mm) range.
