Common Industry Alloys
- P&I Gold Braze 7008 (AWS BAu-6 / AMS 4786) - 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.
- P&I Gold Braze 5025 (AWS BVAu-7 / AMS 4784) - Gold Braze 5025 wets a wide range of high temperature iron & nickel base alloys such as the stainless steels, A286, Inconel & Inconel X very well. It does not alloy excessively with these materials nor produce the severe intergranular penetration normally associated with the nickel based brazing alloys containing boron. Gold Braze 5025 has increased ductility compared to the other gold/nickel alloys, due to its increased level of Pd. Joint clearances of 0.0015” - 0.003” are normally suggested.
- P&I Gold Braze 8218 (AWS BAu-4 or BVAu-4 / AMS 4787) - 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 the aerospace and powergen industries, AMS 4787 can be used in brazing of fuel line assemblies and aero-engine components.
