Cast Iron Electrodes
SUPERLINK BRONZE
A phosphor bronze (Cu-Sn) electrode for braze welding of cast iron, copper alloys, and dissimilar metal joining. Lower heat input than fusion welding. Weld metal is highly machinable and corrosion resistant. Useful for joining or repairing cast iron, copper, brass, and bronze components.

Welding procedure & parameters
DC+ (DCEP). Low heat input — small diameter preferred. Flat position preferred. Preheat cast iron to 200°C–300°C. Clean surfaces with wire brush and flux if required.
Typical applications
Braze welding of cast iron, joining copper to copper alloys, repair of bronze valves and fittings, joining dissimilar metals (copper/brass to steel), ornamental metalwork, plumbing fittings.
Storage & handling notes
Lower joint strength than fusion welding — suitable for non-structural/light-duty applications. Do not use for structural CI repairs. Store dry.
