Product details Safety-Silv® 56FC Brazing Alloy HARRIS Safety-Silv® 56FC is a cadmium-free silver brazing alloy formulated for joining copper, steel, and brass alloys in HVAC and industrial brazing applications. The alloy provides a plastic range of approximately 175°F (70°C), allowing dependable brazing performance even when joint fit-up conditions are not tightly controlled. Its wide melting range supports filling of loose connections while still enabling penetration into tighter joints, making it suitable for fabrication, maintenance, and repair brazing work. Corrosion resistance is generally similar to copper base metals, but zinc-containing alloys should not be used where brazed joints are exposed to concentrated corrosive liquids for extended periods. Key Benefits Suitable for brazing copper, steel, and brass alloysCadmium-free composition for safer brazing environmentsWide melting range supports variable joint clearancesProvides dependable alloy flow and joint formationSuitable for industrial fabrication and repair operationsCommonly used in HVAC and maintenance brazing tasks Specifications Product Name: Safety-Silv® 56FCProduct Type: Silver Brazing AlloySuitable Materials: Copper, steel, and brass alloysCadmium Content: Cadmium-freePlastic Range: Approximately 175°F (70°C)Corrosion Behavior: Similar to copper base metals; avoid prolonged exposure to concentrated corrosive liquidsRecommended Flux Options: Stay-Silv® White flux or Stay-Silv® Black flux for extended heating cyclesAvailable Forms: Standard wire diameters, preform rings, coils, and stripSpecification Compliance: ANSI/AWS A5.8, ASME SFA 5.8 Class BAg-7 Applications Copper and brass component brazingSteel assembly brazing operationsHVAC and refrigeration installationsIndustrial maintenance and fabrication brazingProduction brazing processes FAQs Which metals can Safety-Silv® 56FC join?It is suitable for brazing copper, steel, and brass alloys.
