Neptune G Gas Brazing AlloySKU: RM-4502
For aluminum-cast or sheet, used in thin flow joints or for build-up and bridging. Neptune G is for the maintenance welder who has difficulty welding aluminum. This low temperature alloy, used with Neptune Flux, controls the temperature while brazing and produces a dense non-porous deposit without danger of melting the base metal.
Neptune G joints are up to three times the strength of the base metal. This universal alloy may be used on sheet or cast aluminum. In addition, Neptune G may be used for thin flow joints and for building up missing sections and to bridge large gaps. Download PDF
