Product Specifications

Uses

AM Au-6 Gold Brazing Alloy is used on ferrous, non-ferrous, and super alloys and provides an extremely ductile, high-strength braze joint. AM Au-6 primary applications include brazing of aero-engine components (heat exchangers), and aircraft fuel systems (nozzles and elliptical spray bars). AM Au-6 alloy is also heavily used in electron tubes, vacuum tubes, and wave guides in the electronic industry. Uses also include medical applications, carbide, tube fabrication, and anywhere a critical braze joint is required. AM Au-6 can also be examined after brazing to verify joint integrity and to certify to a Class-A Braze joints (AWS Specification). 

 

Brazing Characteristics

AM Au-6 Gold Brazing Alloy can be successfully brazed onto a wide range of high temperature nickel & iron-based alloys including stainless steels, carbide, and Inconel. A minimum brazing temperature of 1949°F (1065°C) is recommend for furnace and vacuum applications and the use of high-temperature (Black) flux is required when brazing without a protective cover or shielding gas. AM Au-6 is not recommended for joining copper or copper alloys.
