Please Note: The Non-corrosive flux can be either FL-7 from Esprix Technology or Nocolok® from Solvay. Flux percentages by wire diameter (as provided above) were calculated using Nocolok Flux.

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.
HANDY ONE PRODUCT
Handy One is a trademark for a family of flux-cored brazing/soldering 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 aluminum (and silver based) brazing and soldering filler metals and it is available on spools or coils for wire feed applications or as preformed rings and shapes for automated production lines.
Some of the primary advantages of Handy 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.
  • An environmentally friendly, non-corrosive fluxing system
  • Formulations exist for torch, induction or atmospheric furnace
These materials will join 1100, 3000 and 6000 series Aluminum with torch, induction or atmospheric furnaces. While typically cored with non-corrosive (CAB type) flux, the addition of cesium is recommended for improved wetting on 6000 series aluminum alloys. These materials are also available with additional brazing alloy in the form of a fine diameter wire inside the core. This reduces the percentage of flux and increases the volume of alloy, which can be advantageous in some furnace brazing applications.
USES
AL 718 filler metal is generally used to join aluminum and aluminum alloys. It offers excellent corrosion resistance when joining aluminum base metals.
BRAZING & SOLDERING CHARACTERISTICS
AL 718 is a general purpose free flowing brazing filler metal for use with all brazeable aluminums, in all types of brazing processes.
PROPERTIES OF BRAZE & SOLDER JOINTS
Joints made with Al 718 can be as strong as the base metal if designed and processed properly. Factors such as joint length and thickness, fluxing, heat treatment, amount of filler metal, cleanliness, and heating all have an impact on the final joint strength.
