Easy-flo Silver Brazing Fluxes-General Purpose

 Easy-flo Flux Powder 550-800C     EN1045 FH10  The leading brand general-purpose flux, good for hot rodding.
 Easy-flo 100 Flux Paste 550-800C     EN1045 FH10  Smooth general- purpose flux with good overheat resistance.

 These products are popular 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. Specialised fluxes are often required for aluminium bronze, stainless steel and tungsten carbide.

Easy-flo Silver Brazing Flux Pastes- Special Purpose

Easy-flo Low Temperature Grade Flux Paste            550-800C       EN1045 FH10  Smooth paste good for copper alloys and induction heating
Easy-flo Medium Temperature Grade Flux Paste              600-800C       EN1045 FH10  A general-purpose flux paste with good overheat resistance
Easy-flo High Temperature Grade Flux Paste            575-825C       EN1045 FH10  good overheat resistance but provides less cover when molten.

 

Easy-flo Silver Brazing Fluxes for Special Applications

Easy-flo Stainless Steel Grade Flux Paste    550-775C   EN1045 FH10 Additional fluoride, good for stainless steel with short heating cycles.
Easy-flo Stainless Steel Grade Flux Powder    550-775C   EN1045 FH10 Additional fluoride, good for stainless steel with short heating cycles.
Easy-flo Aluminium Bronze Grade Flux Paste    550-775C   EN1045 FH11 For brazing on parent metals (aluminium bronze) containing 2-10% AL

 

Tenacity Brazing Fluxes-Boron Modified

Tenacity No 6 Flux Powder     550-800C     EN1045 FH12  This powder contains boron for improved wetting on tungsten carbide.
Tenacity No. 6 Flux Paste     550-800C     EN1045 FH12  This paste contains boron for improved wetting on tungsten carbide.
Tenacity No. 5A Flux Powder     600-900C     EN1045 FH12  A higher temperature boron-modified flux powder.
Tenacity No 3A Flux Paste     600-875C     EN1045 FH12  This boron modified flux conforms to AMS 3411.

The addition of elemental boron to brazing fluxes improves filler metal wetting on refactory metals and difficult to wet materials such as tungsten carbide. It should be noted that boron-modified fluxes are not suitable for use on low or nickel-free stainless steel if interfacial corrosion is likely to be a hazard in service because they can promote the corrosion mechanism.

Tenacity Brazing Fluxes- Medium and High Temperature

Tenacity No. 4A Flux Powder    600-850C     EN1045 FH10 For brazing larger copper parts and prolonged heating cycles.
Tenacity No. 5 Flux Powder    600-900C     EN1045 FH10 For stainless steel, heavy parts and prolonged heating cycles.
Tenacity No. 20 Flux Powder    750-1000C     EN1045 FH21 For brass/bronze welding with the Argental range.
Tenacity No. 125 Flux Powder    750-1200C     EN1045 FH21 For brazing with JM Bronze filler metals such as F Bronze.
Tenacity No. 125 Flux Paste    750-1200C     EN1045 FH21 For brazing with JM Bronze filler metals such as F Bronze.

These products are designed for components requiring extended heating cycles, low silver or copper based brazing filler metals.

Specialised Tenacity Fluxes

Tenacity No. 2 Modified Flux Powder     550-800C     EN1045 FH10 Specially modified for use as coating on brazing rods.
Tenacity No. 14 Flux Powder     550-750C     EN1045 FH10 A very fluid flux that prevents red staining on brass.

 

Alu-flo Fluxes For Brazing Aluminium

Alu-flo No. 1 Flux Paste      450-650C   Corrosive Flux Residues A chloride based flux suitable for use with Alu-flo HT and MT.
Alu-flo No. 2 Flux Powder       575-650   Non-Corrosive Residues A fluoride based flux suitable for use with Alu-flo HT and MT.

These products are designed for low temperature aluminium brazing in air. 

Stop-flo Stop off or Parting Compounds

Stop-flo No. 1 Braze Stop-off        Up to 1600C Standard stop-off compound for use on general engineering metals.
Stop-flo No. 2 Stop-off        Up to 1600C Specially formulated stop-off compound for use on titanium alloys.

These products are formulated to prevent the flow and wetting of molten brazing filler metal across the surface of a component during the brazing process. They are suitable for vacuum furnace, controlled atmosphere or air brazing processes. Stop-flo No. 1 and Stop-flo No. 2 are available in paint, paste or tape form. Residues of Stop-flo No. 1 or No. 2 before and after brazing are best removed using a water wash.
