What is the correct technique for brazing with the Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube?

Proper joint preparation is critical for sound brazed joints: clean all joint surfaces to remove oil, oxide, and scale using emery cloth or a wire brush. Maintain proper joint clearance for capillary flow. Heat the base metal — not the filler rod — to brazing temperature before touching the rod to the joint. The heat-to-flow sequence ensures proper capillary action. Allow the joint to air cool before quenching to avoid thermal shock cracking.

Q: What is the Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube used for?

The Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube is a silver brazing alloy (Safety-Silv 45). Silver brazing alloys produce strong, ductile joints on ferrous metals, copper, copper alloys, and many dissimilar metal combinations. They flow at lower temperatures than conventional copper-phosphorus alloys, reducing base metal distortion. Always use the appropriate brazing flux (Harris Stay-Silv White or Black Flux) with silver brazing alloys.

Q: What diameter is the Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube available in?

The Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube is available in 1/8 diameter. Rod or wire diameter selection depends on joint gap clearance and feeding method: narrow-gap joints with tight clearances benefit from thinner rod (easier to feed into the joint), while larger-gap joints require more filler and may work better with thicker rod. Pre-placed rings or preforms are available for production brazing of consistent joint geometries.

Q: Does the Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube require brazing flux?

Silver brazing alloys require a compatible brazing flux to prevent oxidation during heating and to aid flow. Harris Stay-Silv White Flux is recommended for most silver brazing applications at brazing temperatures up to approximately 1600°F. For higher-temperature alloys or extended-cycle brazing, Stay-Silv Black Flux handles temperatures up to approximately 1800°F. Apply flux to all base metal surfaces before heating.

Q: What package size is the Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube available in, and how should I store it?

The Harris 45F618L - Safety-Silv 45F Flux-Coated Silver Brazing Alloy - 1/8 in (3.2 mm) - (2) 1 lb bags/Tube is available in 1 lb packages. Store brazing rod in a clean, dry location away from oils and solvents. Silver alloys are stable at room temperature with no special storage requirements. Protect rod surfaces from contamination that could interfere with flux wetting and flow during brazing.

Safety-Silv 45 flux-coated high silver brazing alloy 1/8 x 18 in. x (2) 1 lb. bags/tube

Overview

Safety-Silv 45 flux-coated high silver brazing alloy performs like a 45% silver cadmium-bearing alloy, but is cadmium-free. The flux coating on the wire eliminates the need for manual flux application. It has a lower melting temperature than Safety-Silv 45. Its excellent fillet-forming quality produces high-strength ductile joints. Certified to NSF Standard 51 for food service equipment.

Features

General purpose cadmium-free silver brazing alloy
Excellent joint strength and ductility at moderately higher temperature with a melting range of approximately 145◦F (63◦C)
Good ductility and capillary flow
Fillet forming qualities are suitable for filling loose connections
Recommended joint clearance of 0.003 in. - 0.006 in. (0.08 mm - 0.15 mm)
Popular choice to braze copper, brass, steel and Stainless Steel
Fluidity rating of 6.5
Flux-coating eliminates the need for manual flux application
Conforms to EU RoHS directive
