Fluxes

ALU-FLO brazing fluxes are chloride and fluoride-based, designed for low-temperature aluminium brazing in air.

EASY-FLO are general-purpose silver brazing fluxes. They can be used on the common engineering metals including copper, copper alloys (brass, bronze, nickel silver, copper nickel), nickel alloys, steel, stainless steel and tungsten carbide. They are available in both paste and powder form and with varying working range, activity and overheat resistance and can be supplied according to Rolls-Royce (MSRR 9500) specification. EASY-FLO™ flux powder has excellent flux pick-up onto warm brazing rod when using the hot rodding technique.

Soft solder fluxes are available in forms with both corrosive and intermediate/low corrosivity residues. They can be used on copper, copper alloys, carbon steel and stainless steel.

TENACITY No. 6 contains an addition of elemental boron which improves filler metal wetting on refractory metals and difficult to wet materials such as tungsten carbide and PCD. Variants, such as TENACITY No. 125 are also available which are suitable for bronze welding and components requiring extended heating cycles, low silver or copper-based brazing filler metals.
