What is the correct technique for brazing with the Harris 40350H - Safety-Silv 40 Silver Brazing Alloy - 1/16 in (1.6 mm) - 50 toz Coil/Box?

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 40350H - Safety-Silv 40 Silver Brazing Alloy - 1/16 in (1.6 mm) - 50 toz Coil/Box used for?

The Harris 40350H - Safety-Silv 40 Silver Brazing Alloy - 1/16 in (1.6 mm) - 50 toz Coil/Box is a silver brazing alloy (Safety-Silv 40). 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 40350H - Safety-Silv 40 Silver Brazing Alloy - 1/16 in (1.6 mm) - 50 toz Coil/Box available in?

The Harris 40350H - Safety-Silv 40 Silver Brazing Alloy - 1/16 in (1.6 mm) - 50 toz Coil/Box is available in 1/16 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 40350H - Safety-Silv 40 Silver Brazing Alloy - 1/16 in (1.6 mm) - 50 toz Coil/Box 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 40350H - Safety-Silv 40 Silver Brazing Alloy - 1/16 in (1.6 mm) - 50 toz Coil/Box available in, and how should I store it?

Brazing alloys are sold in various rod lengths and weights — common sizes include 1 lb, 5 lb, and 25 lb packages. Store in a dry location free from oil and solvent contamination. Silver brazing alloys are stable at room temperature and do not require special controlled-atmosphere storage. Keep surfaces clean to ensure proper flux adhesion and capillary flow.

Safety-Silv 40 high silver brazing alloy 1/16 in. x 1 ea. 50 toz. coil/box

Overview

Safety-Silv 40 is a ductile, free-flowing alloy that offers economy, good penetration into tight connections and medium temperature. Silver to light yellow color like polished brass.

Features

Cadmium-free, silver brazing alloy
Good ductility
Often used for corrosion applications or high temperature service, so suitability for the brazing alloy should be evaluated for the intended condition
Good replacement for hazardous cadmium-bearing filler metals
Moderate temperature alloy with a medium plastic range, making it suitable for brazing assemblies with wider gaps
Corrosion resistance is generally similar to copper base metal, but due to its zinc content it should not be used if the braze is exposed to concentrated corrosive liquid for long periods of time
Fluidity rating of 8.0
Complies with the EU Reach & RoHS directive
