Pro-One Flux Cored Silver Brazing Alloy
Argeco 108T

This proprietary new family of brazing & soldering products eliminates the need for a separate fluxing operation, which can result in a significant increase in productivity while minimizing flux exposure to your personnel and plant equipment.
Pro ONE PRODUCT
Pro One is a trademark for a family of flux-cored brazing materials Small logothat offers numerous advantages compared to traditional metal joining methods. It consists of a filler metal in strip form that is rolled around a powdered flux. Formulations currently exist for silver (and aluminum based) brazing filler metals and it is available on spools, coils or rods for wire feed applications and as preformed rings and shapes for automated production lines.
Some of the primary advantages of Pro One cored wire include:
  • It simplifies the brazing process by eliminating the manual fluxing operation; this also reduces flux exposure to your brazing personnel.
  • Joint quality and throughput can be improved due to the consistent application of flux and filler metal.
  • Reduces heating time and secondary post braze operations, increasing productivity and throughput.
  • Improved strength due to a reduction in flux inclusions at the joint interface.
  • Reduces the flux in your wastewater effluent by as much as 75%.
  • Multiple formulations exist for a variety of base metals, joint designs and heating methods.
These materials will join ferrous and non-ferrous metals including steel, stainless steel, copper, brass and bronze.
USES
Argeco 108T is a good general purpose, intermediate temperature brazing alloy for use on copper, brass, nickel-silver, bronze and other nonferrous alloys as well as mild steel, stainless steel, nickel and Monel metal.
BRAZING CHARACTERISTICS
Argeco 108T is an intermediate temperature filler metal that may be used as a cadmium free substitute for Easy-Flo 30 or used in applications where an intermediate silver-copper-zinc alloy is needed. It liquates moderately, but this property is useful in bridging gaps where poor joint fitups cannot be avoided. It flows well on steels, copper and copper alloys.
BRAZING FLUXES AVAILABLE
Protechno has several different fluxes available depending upon the material form (wire or preformed shape) as well as base metals and heating methods utilized.
    Restrictive Flux - protects the parts being joined, yet restricts the flow of the filler metal, enabling the building of fillets and minimizing post braze secondary operations. This flux is recommended for most hand feed or wire feed applications. Flux content is typically 12% (+- 3%) of the total volume.
    Free Flowing Flux - This very fluid flux provides excellent protection of your parts and facilitates filler metal flow. Recommended for preformed ring applications, it is typically 18% (+- 3%) of the total volume.
    Heat Resistant Flux - Boron modified flux for large mass assemblies or long heating cycles. It is also typically 18% (+- 3%) of the total volume and also recommended for preformed ring applications.
    Please Note: Flux percentages may vary depending upon material size and finished form, please contact Protechno's Technical Services Department for specific product and process parameters. phone 414-769-6000, fax 414-769-1093.
