High quality rosin core solder made by Kester. This is a leaded solder and is commonly used in electronics assembly or repair.

Rosin 44 is a high activity RA core flux designed for excellent instant wetting action, even on Nickel surfaces. Although 44 is a RA-based material, the residues are non-corrosive if not cleaned. Per J-STD-004, 44 is classified as ROM1 flux.

  • Alloy: Sn63Pb37
  • Diameter: .031
  • Core size: 66

    More information from the manufacturer:
    "44" Flux Residues: The question is frequently asked are "44" flux residues harmful to an assembly.
  • The 44 flux residues are non-conductive and non-corrosive. Residue removal would normally be for cosmetic reasons. If the assembly is in a heated environment and sees temperatures of over 160F the flux residues will re-melt. When liquid (at high temperatures) the residues are conductive.
