What is the Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R used for?

The Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R is a brazing filler metal used in torch brazing, induction brazing, and furnace brazing applications. Brazing produces strong, leak-tight joints on a wide range of base metals at temperatures above 840°F (450°C) but below the base metal's melting point. Select the filler alloy based on base metal type, service temperature, and required joint strength.

What diameter is the Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R available in?

The Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R 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.

Does the Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R require brazing flux?

A compatible brazing flux is required for most brazing operations to prevent oxidation on base metal and filler surfaces during heating. Apply flux to joint surfaces before heating. After brazing, remove all flux residue with warm water and a brush — flux residue is corrosive and will attack the joint over time if not cleaned.

What is the correct technique for brazing with the Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R?

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.

What package size is the Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R available in, and how should I store it?

The Harris BLOCKADE 1/16 DIA X 36 X 25# PKG - BK336R is available in 25 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.
