TECHNICAL DATA SHEET
SUPER FLUXO 03 – White Brazing Flux
SUPER FLUXO 03 white paste flux is a homogenous brazing flux ideally suited for use with a variety of base
metals. A mixture of boric acid and fluoride compounds, it is formulated to provide smooth flux application, even
coverage, and excellent protection during braze heating cycles.
Fluxo Prata white flux is recommended for brazing copper and copper alloys, (except aluminum bronze), steel,
stainless steel, nickel alloys and other ferrous base metals. It is used with many high silver brazing filler metals
of the AWS A5.8 BAg classifications and ISO 17672 class Ag alloys.
It is also suitable for use with many phosphorus-copper-silver alloys, (AWS BCuP and ISO CuP), for brazing
copper to brass.
Flux may be water thinned but care should be taken to avoid excess dilution.
Flux turns clear, (transparent), close to brazing application temperature. This is a useful indicator you are ready
to apply braze wire or rod.
ACTIVE RANGE
550°C – 950°C
FLUX REMOVAL
Post braze flux residue should be removed to avoid potential corrosion. A Flux condition near brazing temperature
hot water wash and brushing with a rag or non-woven abrasive pad, (e.g.
Scotch-Brite™), is often sufficient. Additional measures include mechanical cleaning with a wire brush, steam
jet, or abrasive blasting media such as grit, soda, or dry ice.
Production post-braze cleaning can also be accomplished with proprietary chemical formulas such as Bernite®
45 available from Harris Products Group. This approach is suitable where parts lend themselves to a water
bath/tank immersion.
