Metals-Aluminium heat exchangers

NOCOLOK® Flux is used in brazing aluminum heat exchangers. Once the surfaces have been freed from residue with this ideal fluxing agent, condensers and evaporaters can be joined together.  Products ANTAROX BL-225 ANTAROX BL-225 low foaming surfactant for brazing flux suspensions (up to 50 °C) CsAlF-Complex Cesium fluoroaluminates are particularly suitable for flame brazing at temperatures between 430° - 480° C. NOCOLOK Binder (water soluble) Component for flux binder mixtures for selective fluxing NOCOLOK Flux plus Binder Mixture -Preparation ready for use- Flux-binder mixture for selective fluxing NOCOLOK System Binder (water-based) Binder system for flux binder mixtures for selective fluxing NOCOLOK Thickener (water soluble) Component for flux binder mixtures for selective fluxing NOCOLOK® Cs Flux NOCOLOK® Cs Flux is specifically made for brazing magnesium-containing aluminium alloys NOCOLOK® Flux NOCOLOK® Flux is not only suitable for both furnace and flame brazing applications, but also for induction applications. It is used in the automobile sector, households, refrigeration applications, and for tube connections. NOCOLOK® Flux Drystatic NOCOLOK® Flux Drystatic is a flux for brazing of aluminium using electrostatic/dry powder application NOCOLOK® LM Flux NOCOLOK® LM Flux is a flux for brazing aluminium. Particularly suitable for process conditions with a maximum brazing temperature below 595 °C. NOCOLOK® Sil Flux (coarse grade) Particularly suitable for brazing aluminium without additional filler metal. NOCOLOK® Sil Flux (fine grade) Particularly suitable for brazing aluminium without additional filler metal. NOCOLOK® Zn Flux NOCOLOK® Zn Flux: During brazing, potassium fluoroaluminates ( flux ) are generated by the brazing agent in contact with Al / Si filler metal. In addition, zinc is produced and diffuses into the aluminium surface.   Back
