Indium CW-901 Acid-Cored Wire
• Versatile acid-type inorganic flux for use in industrial applications
• Excellent for use with all metals, except aluminum and magnesium
• Water rinse necessary to remove flux residue after soldering
• Not suitable for electrical or electronics applications
CW-901 wire solder is cored with an inorganic acid flux for industrial applications. It is highly active to accomplish rapid soldering at controlled conditions for most metals, including copper, brass, bronze, nickel alloys, mild steel, and stainless steel.
Due to the corrosive nature of this flux residue after soldering, CW-901 requires removal of the flux residue. Complete residue removal can be accomplished by a chemical neutralizer rinse followed by several water washings. A first rinse in water with the addition of 2-3% HCl helps remove flux residues and facilitates better second- and third-stage cleaning. All flux residues should be thoroughly removed to prevent corrosion.
CW-901 has a shelf life of 2 years when stored in a dry, non-corrosive environment such as a low-humidity dry cabinet. Direct sunlight, excessive humidity, and storage near heat sources should be avoided.
