SUPERFLOW 56 CF BAg-7 Cadmium-Free Silver Brazing Alloy – 1/16" x 20"

56% silver, cadmium-free brazing alloy with a narrow melting range and low working temperature.
SUPERFLOW 56 CF is a high-silver brazing alloy classified as AWS A5.8/A5.8M BAg-7. Formulated with approximately 56% silver, this cadmium-free alloy provides excellent flow, wetting, ductility, and joint penetration while operating at a lower working temperature than other cadmium-free alloys in the SUPERFLOW family.

SUPERFLOW 56 CF is commonly used to join compatible combinations of copper, brass, steel, bronze, and stainless steel. Its high-silver composition, narrow melting range, and light-colored finished joint make it especially useful for precision brazing, food-handling equipment, stainless steel fabrication, and applications where appearance and controlled heat input are important.

Important Ordering Information: This product is supplied in 1/16" diameter x 20" long brazing alloy wire and is priced by the troy ounce (TO).

Chemical Composition

Physical Data

High-Silver BAg-7 Brazing Alloy

SUPERFLOW 56 CF is a high-silver BAg-7 brazing alloy formulated with silver, copper, zinc, and tin. Washington Alloy specifies a silver content of 55.0–57.0%, giving the alloy approximately 56% silver.

The alloy is designed to provide premium flow and wetting characteristics while maintaining good ductility and penetration. Its narrow melting range helps provide controlled brazing performance for precision joining applications.

Cadmium-Free Formulation

SUPERFLOW 56 CF is a cadmium-free silver brazing alloy. Its listed chemical composition consists primarily of silver, copper, zinc, and tin.

The cadmium-free BAg-7 formulation makes it suitable for applications where a high-silver, cadmium-free brazing filler metal is specified.

Lower Brazing Temperature

One of the key characteristics of SUPERFLOW 56 CF is its relatively low working temperature. Washington Alloy lists a solidus temperature of 1145°F (618°C) and a liquidus temperature of 1205°F (652°C).

The manufacturer lists a brazing range of 1205–1400°F (652–760°C). This lower temperature range can be beneficial in applications where controlling heat input to the assembly is important.

Stainless Steel & Food-Handling Applications

Washington Alloy identifies SUPERFLOW 56 CF as a strong choice for food-handling equipment and applications requiring a good color match on stainless steel and nickel alloys.

The alloy's white-to-light-gold color and high-silver formulation also make it useful where the appearance of the finished brazed joint is an important consideration.

How This Product Is Sold

Please Note: This product is priced using a troy-ounce (TO) unit of measure. The brazing alloy is supplied as 1/16" diameter x 20" long wire.
