Introducing the world's first boric acid-free smart flux

ECO SMART® is a unique, patent-pending flux that is designed with color change technology that lets you know when it is time to braze.

Its boric acid free environmentally friendly formula starts out as a green color that changes to clear when the flux becomes active.

Green - Color Change Brazing Flux

Harris ECO SMART Color Change powder fluxUsage for powder and paste: brazing steel, stainless steel, Monel®, nickel, copper, brass, bronze and other ferrous and non-ferrous metals and alloys.

Use with Stay-Silv®, Safety-Silv® and other brazing filler metals. Extremely fluid. Will penetrate the tightest joints. Not subject to recrystallization (lumpiness-hardening). May be water thinned. Remove all flux residue on completion of brazing.

Residue can be removed with wire brush and hot water; no acid solution required. Absence of boric acid results in less airborne water absorption and clumping of powder.

DETAILS

Paste Spatter: Very little spatter for undiluted flux.
Powder Splatter: No spatter for undiluted flux.
Paste Life - Base Metal Protection: Excellent throughout the active range - Prevents oxidation of base metal during brazing operation.
Powder Life - Base Metal Protection: Good throughout the active range - Prevents oxidation of base metal during brazing operation. Better protection than Eco Smart Powder Flux.
Capillary: Excellent
Flux removal: Remove flux residue after brazing with wire brush with hot water.
Base Metals: Copper alloys (copper, brasses & bronze) Promotes optimal bonding between like and dissimilar base metals.
Filler Metals: BAg, LAg, LCuP and BCup Alloys
Brazing Methods: Flame, induction and furnace brazing.
Active Temperature Indication: Flux color changes from green to clear to indicate that active temperature has been reached.
Paste Consistency: Smooth, with very little separation; flux remains in suspension when stored for extended periods of time.
Powder Consistency: Uniform. Not gritty.
Powder Hygroscopicity: Absorbs less water from the air, resulting in less clumping than fluxes containing boric acid.
Paste Application: Brazing rod can be dipped in the flux or flux can be brushed on the surface of the braze joint.
Powder Application: Flux is excellent for hot-rodding (Dipping the heated end of the brazing rod into the flux powder to achieve a flux coat). It can also be mixed with water or alcohol as needed, and applied to base metal.

High Heat Brazing Flux

Harris ecoSMART High Heat powder fluxUsage for powder and paste: brazing steel, stainless steel, Monel®, nickel, copper, brass, bronze and other ferrous and non-ferrous metals and alloys.

Use with Stay-Silv®, Safety-Silv® and other brazing filler metals. High Heat flux is designed to extend the temperature and life of the flux. This is helpful during longer part heating cycles, or in cases of intense localized heating, such as induction brazing. Extremely fluid. Will penetrate the tightest joints. Not subject to recrystallization (lumpiness-hardening).

Residue can be removed with wire brush and hot water; no acid solution required. Absence of boric acid results in less airborne water absorption and clumping of powder.
