Item # White Flux
White Brazing Flux
Designed for use with all silver alloys on all metals except aluminum, magnesium or titanium, White Flux is active in the 1100 ºF to 1600 ºF range. Choose from 1#, 5#, 30# and 50# containers.
White Flux is a water base paste consisting of a unique combination of potassium salts of fluorine and boric acid. It is recommended for use with torch, induction, furnace, resistance, dip and other heating methods. Our quality control ensures a creamy consistency. White Flux can be used in the concentrated form or can be diluted. Heating the flux to 150 ºF – 175 ºF dilutes it to a thin consistency without water. White Flux also readily dilutes to a thin consistency using 60 cc of cold or hot water per pound of flux.
5 lbs. flux – mix with 300 cc water (1/3 quart)
30 lbs. flux – mix with 1800 cc water (2 quarts)
50 lbs. flux – mix with 3000 cc water (3 1/4 quarts)
Water diluted flux retains good suspension without settling.
White Flux can be applied using a brush, dip or spray. The wetting ability is excellent. Vertical adherence as applied and upon heating is excellent. There is no spatter on heating with concentrated flux, slight spatter will occur with water diluted flux due to escaping steam. Ultra Flux has excellent adhesion without cracking when applied to parts which are air dried or heat dried before brazing. It also has a long storage life without crystallizing or caking.
Protection of parts and flux life under heating are excellent. Oxide absorption and brazing alloy flow are also excellent on all metals when White Flux is used. Flux residue removal is easy with hot water. This feature saves time and problems with corrosion later on.
When brazing with White Flux, the braze joint quality is excellent. White Flux conforms to the various AMS, AWS and Government specifications which are listed on the flux label.
