Most of our alloys are available as solid core (no flux in the center). The most popular diameters are between 0.010”/0.254mm and 0.062”/1.52mm; however, SnAg and AuSn alloys are available in diameters less than 0.010”/0.254mm.
Flux-cored wire is generally used for manual soldering or rework, and is increasingly used in robotic soldering applications. It contains the flux in the center to facilitate the soldering process and eliminate the need for a separate flux. A variety of flux cores are available including no-clean, water-soluble, and halogen-free. Flux-cored wire is also used for soldering processes that do not involve electronics. Typical alloys for flux-cored wire include:
Indium Corporation is quickly becoming known as one of the highest quality, full line suppliers of flux-cored wire solder. Indium Corporation uses only “conflict-free” and grade A (per ASTM B32) metals, as well as other high purity metals for its flux-cored wire. Our materials have been tested and certified to meet IPC J-STD-004B and other relevant industry specifications, including the legacy military specification QQ-S-571f. Indium Corporation’s flux-cored wire is well known for its:
Evenly layer winding
Low oxide shiny appearance over time
Non-offensive odor for the 800 series and 200 series fluxes
The unique characteristics of indium metal make it an ideal solution for many soldering and sealing applications. As a wire, pure indium provides an excellent hermetic seal since it fills the imperfections in the mating surfaces. Pure indium also remains malleable at cryogenic temperatures so that sealing applications operating in harsh conditions are not compromised.
