White Paste Brazing Flux
Weldcote White Paste Flux
Weldcote White Paste Flux is a creamy, white silver brazing paste flux that is active and protective to 870°C/1,600°F. It was formulated for the majority of brazing operations, and is recommended for use with copper and copper-based alloys, steel, stainless steel, nickel, carbides, precious metals and heat-resistant alloys. Weldcote White Paste Flux is available in dispensable form suitable for spraying or other automatic application methods. The flux will not harden or crystallize, retaining its creamy texture up to two (2) years.
- Sold in quantity of 1 lb.
Used in a wide variety of joining applications for many different finished products including; appliances, automotive, carbide tools, dental tools, orthodontia, farm machinery, heat exchanges, heat equipment, maintenance, mining tools, musical instruments, plumbing fixtures, refrigeration and air conditioning, ship repair, steel furniture and welding equipment.
May be used in concentrated form or diluted with water to a thinner consistency. Heating the flux to 60°C/140°F – 82°C/180°F makes it less viscous and more reactive. Heat the flux slowly to reduce spattering or excessive bubbling. The raw flux and residues are soluble in hot water (at least 140°F/60°C). Chipping or grinding is not necessary.
- Remove any oil, grease, or other cont aminants from the surface to be brazed.
- Apply flux to joint by dipping, swabbing or brushing area being brazed. The flux may be used as supplied or diluted.
- Apply, heat, by torch, induction or other means to area being brazed after flux has been applied to activate the flux.
- Feed the braze alloy into the joint, unless a brazing perform is already in place.
- Clean flux residues from brazed joint using hot water (60°C ± 5°C/140°F ± 10°F) for best results. If unavailable, room temperature water may also be used.
