Silver-flo TM 55 is a silver brazing filler metal. It combines a low brazing temperature with a short melting range. Silver-flo 55 is very free flowing and produces neat joints with small fillets. These characteristics make Silver-floTM 55 an excellent general-purpose silver brazing filler metal. In many countries it is accepted as the best cadmium-free alternative to the low-melting cadmium containing filler metals. For example, it is used as a substitute for alloys such as Easy-flo TM.

Joints made with Silver-flo 55 are suitable for seawater applications, being resistant to dezincification. The optimum joint gap for this filler metal at brazing temperature is normally 0.05-0.15mm.

Melting range:630-660 C

Uses for this Product:

Silver-floTM 55 can be used to join all the common engineering materials (excluding aluminium) such as copper, copper alloys (including, brasses, bronzes, gun metal, nickel silvers, aluminium bronze, copper nickel), steels including, mild, carbon, tool steel, stainless steels, low alloy steel), tungsten carbide and PCD segments. On large or difficult to wet tungsten carbide pieces specialised silver brazing filler metals containing nickel / manganese are often preferred.

Conditions for Use:

This filler metal is mainly used for brazing in air with a flux.

Tenacity No 5 TM Flux Powder

TenacityTM No.5 Flux Powder is a brazing flux suitable for use with silver brazing filler metals. It is active at 600 C and is effective with alloys that melt below 850 C.

TenacityTM No.5 shows good overheat resistance when compared to other silver brazing fluxes. This characteristic is useful when brazing stainless steel components for example, where because of its poor thermal conductivity there is a risk of overheating causing the flux to become exhausted and ineffective.

TenacityTM No.5 also shows an extended life at brazing temperature (time / temperature stability). This feature is important when brazing large assemblies in steel or copper for example, or wherever prolonged heating is necessary.

Conforms to: EN 1045: FH10

Working range: 600-900 C

Directions for use:

TenacityTM No. 5 flux powder should be mixed with water and a few drops of liquid detergent to form a thick paste. Paste should then be brushed onto the joint surfaces before assembly. Further flux should then be applied externally either side of the joint mouth.

It is good practice to mechanically clean and degrease the joint surface before applying flux. Heat slowly and evenly to the brazing temperature, without local overheating. Use the flux as a temperature guide - it will become clear or opaque as brazing temperature is approached. If blackening of the flux occurs this is often a sign of insufficient flux, overheating or flux exhaustion.
