LucasMilhaupt® Handy Flo® 6 Brazing Rods Copper to Copper/Brass .125" x .050" x 20" (28 pk)

APPLICATIONS

Handy-Flo 6 is a silver-copper-phosphorus alloy used for brazing copper to copper or copper to copper alloys, most often in the HVAC industry. It should not be used on ferrous or nickel base materials due to the brittle intermetallic that forms. The phosphorus in the Handy-Flo 6 serves as a fluxing agent, so the alloy does not require flux for copper to copper joints. Flux is recommended for copper to brass joints.

FEATURES

• Handy Flo 6 is a copper-rich, intermediate temperature alloy that is self-fluxing on copper by virtue of its phosphorus content. The self-fluxing property of this alloy is effective on copper. With copper-base alloys, such as brass or bronze the joints should be fluxed with Handy Flux. Handy Flo 6 should not be used on nickel-base or ferrous alloys, as the phosphorus reacts with the nickel or iron to form brittle compounds at the interface of the joints.
• Handy Flo 6 is useful where close clearances cannot be maintained or where fillets are specified. It has a tendency to liquate if heated slowly through the melting range.
• Joins CU to CU (phosphorus serves as flux)
• Joins CU to Brass (flux is recommended)
• Melts & flows at temperatures very close to 15% Ag
• Slow flow
• Made in USA
