Flux formulations for aluminium brazing, soldering, and welding electrode coatings
Fluoride flux feedstocks for aluminium brazing (Nocolok-style), silver brazing, stainless-steel and nickel brazing, and arc-welding electrode coatings.
Potassium fluoride and potassium fluoborate as base feedstocks for KAlF4 / K2AlF5 (Nocolok-type) non-corrosive aluminium brazing fluxes used in automotive heat exchangers and HVAC.
Potassium and sodium bifluorides — high-activity fluxes for vacuum and atmospheric brazing of stainless steel, nickel super-alloys, and Hastelloy.
Potassium fluoborate, potassium bifluoride and fluoboric acid as primary actives in silver-brazing flux paste and powder formulations for plumbing, HVAC, jewellery and precision braze work.
Cryolite, calcium fluoride, lithium cryolite and lithium fluoride as basic-coating constituents in stick / SMAW welding electrodes for low-hydrogen and basic-coated rods.
Calcium fluoride and synthetic cryolite as flux components in agglomerated and fused submerged-arc welding fluxes for pipeline, shipbuilding and structural-steel SAW.
Potassium bifluoride and fluoboric acid in flux pastes for oxy-acetylene gas brazing and gas welding of copper, brass and bronze.
