There are special fluxes for welding, soldering and brazing. Saru Silver is involved with the manufacturing and exporting of varied fluxes and pastes which are used in brazing, welding and soldering. Our fluxes are in the form of paste or powder and widely applicable for various joining process. It is very important to use the right flux for the right purpose because the use of the wrong flux or a poor application technique can have a significant bad effect on joint quality. Brazing flux plays an important role in virtually all brazing processes. Soldering fluxes are usually categorized as corrosive, non-corrosive or intermediate. However, the choice depends on the melting range of the solder, the metals being joined, and whether the residues are to be removed after soldering. Similarly there are special fluxes for welding.


Specifications

	Product Name Applications Comments Super Flux-A (Powder) This is an all purpose , low temperature flux. It is used in brazing both ferrous and non-ferrous metals. It is also used in alloys using silver brazing filler metals. The flux in powder form begins to melt and dissolve oxides at 340°C. At about 600°C, it is fully molten and provides adequate protection upto 750°C. Such type of flux is excellent in hot rodding operation. It is used to braze weld where the hot brazing rod is moved into the dry powder. It is easily cleaned in hot water. Equivalent to ESAB's Rupatam A flux Super Flux-A1 (Powder) Such type of flux is used for applications where a dry low volatile flux is need. When the temperature is in 650-815°C range, it is recommended for use. It is excellent in hot rodding operations and can easily be cleaned. Equivalent to Handy Dry Flux 6040. Super Flux-A (Paste) This again is a general purpose, low temperature flux. This type of flux provides excellent adhesion and creamy smooth consistency. It is used for brazing all ferrous and non-ferrous alloys. The flux begins to melt and dissolves oxides at 320°C. It is fully molten at 600°C and excellent protection of parts upto 870°C is provided. It is easily cleaned with hot water. Equivalent to Handy Flux (Paste) Super Flux Type D & DB (Slurry) Having the same formulations as Super Flux-A (Paste), it is used for automatic dispensing as controlled dabs or sprays. There are additives in this flux to provide a lower (pourable) viscosity. Type DB flux has an additional ingredient for use with more refactory oxides, as seen in automated brazing of carbides. Equivallent to Handy Flux Type D & DB (Slurry). Super Flux-B (Powder/Paste) Available in both powder and paste form. It is used for brazing high chromium stainless steels, chromium and tungsten carbides, and molybdenum alloys. The temperature range is 600-925°C. Such type of flux is useful in applications where local overheating may occur, as in fast induction heating. Equivalent to Handy Flux Type B-1 Super Flux-C (Powder/Paste) Available in both powder and paste form. It is used for brazing aluminium-silicon bronze (A1-7, Si2, Cu-bal.), aluminum bronze (A1-5 to 8,Cu-bal.), and nickle-aluminium-bronze(A1-9.5, Ni-5, Fe-2.5, Mn-1, Cu-bal.) using silver brazing filler metals. This flux is not recommended for use with aluminum or titanium-base alloys. Equivalent to Handy Flux Type A-1. Super Flux-D (Powder/Paste) Like in furnace brazing, this is used for applications with long heating cycles. It is also used in induction heating operations, where there is the tendency of overheating. Active range: 650-870°C. Equivalent to Handy Flux Type LT. Super Flux Hi- Temp This type of flux is used where brazing temperature is in the range 870-1100°C or for long periods of time above 785°C. Equivalent to Handy Hi- Temp Flux. Super Flux-E (Liquid) This flux is in liquid form. It is used for blazing in furnaces with poor atmosphere . Super flux E is used for joining jewelry parts above 625°C. This is basically used where only a limited fluxing ability is required. Equivalent to Handy Liquid Flux. Super Flux Hi-Temp M (Powder/Paste) It is used in the brazing of carbides, stainless steels, alloy steels, and nickel based alloys using gold and copper alloys filler metals. The required brazing temperature is between 900 and 1200°C. Equivalent to Handy Flux Hi-Temp M. Super Flux-BRS (Powder) This type of flux is used for brazing or fusion welding various ferrous and non-ferrous metals. It is also used in alloys like cast iron, steels, brass etc. using Cu-Zn (brass) filler metals. Equivalent to ESAB's Brazotectic Flux. Super Flux BRZ (Powder) This flux in powdered form is used for brazing various ferrous and non-ferrous metals and alloys using Cu-Sn (bronze) based filler metals. Equivalent to ESAB's Bronzotectic Flux. Alumibraze-A (Powder) Used for brazing aluminum and its alloys using A1-12%Si filler metal. Equivalent to ESAB's Albratectic Flux. Alumibraze-B (Powder) It is similar to Alumibraze-A. It becomes active at a lower temperature which minimizes damage to the aluminum base metal. Such type of flux is suitable for brazing thin sections. Equivalent to Handy Flo-700 Flux. Alumiweld (Powder) This flux is used for welding aluminum and its alloys. Equivalent to ESAB's Alotectic Flux. Stainweld (Liquid) Stainweld is used for welding stainless steels using niobium and other stainless steel rods. Equivallent to ESAB's Botectic Flux. Castweld-A (Powder) For welding cast iron. Equivalent to ESAB's Castox Flux. Cupopaste-A This flus is a copper brazing paste for furnacing brazing steels. Solderflux-A (Paste) Used for soldering applications. Active range: 260-425°C. Equivalent to Handy Flux Type TEC.
