JO FLUX

• Mix readily with water to form a smooth paste free from coarse crystals.
• Retain its paste form for a reasonable time and be capable of being re-mixed if it dries out.
• Wet the work to which it is applied as an aqueous paste.
• Cover the work adequately while in the stage of being dried by heating, without separating to exposed islands of bare metal.
• Remain on vertical surface when fused.
• Melt at a lower temperature than the melting point of brazing material to be used with it.
• Be capable of dissolving the oxides of the metals on which it is used.
• Retain low viscosity to permit its ready displacement from capillary gaps by brazing material.
• Have a reasonably long life without tiring when brazing operations are prolonged.
• Have residues which are easy to remove.

Unfortunately it is not possible to combine all these properties in a universal flux capable of satisfactory performance at low & high temperature and with all base metals. The JO FLUX range of fluxes does however; cater for most circumstances which arise in low & high brazing temperature operations on a wide variety of materials.
