Self-Fluxing Manganese Bronze Brazing Rod for Steel, Cast Iron & Malleable Iron Repairs
CIGWELD Comweld Comcoat C is a premium, flux-coated manganese bronze filler rod engineered for braze welding steel, cast iron, and malleable iron. Classified as RB CuZn-C under AWS standards, this self-fluxing, low-fuming rod eliminates the need for separate flux application, making it a fast, reliable choice for workshop maintenance, fabrication, and general repair welding.
Key Features
- Self-Fluxing Formula – Blue flux coating is factory-applied, so there's no need to dip or apply separate brazing flux, saving time and reducing prep work
- Low-Fuming Manganese Bronze – Produces significantly less smoke and fume during use compared to uncoated bronze rods, improving workshop air quality and operator comfort
- High Bond (Transverse Tensile) Strength – Delivers strong, durable joints with excellent load-bearing capability, ideal for structural and repair applications
- Approx. 460 MPa Tensile Strength with ~35% Elongation – Produces tough, ductile joints that resist cracking under stress and vibration
- Distinctive Blue Coating – Allows instant visual identification in busy workshops, reducing mix-ups with other filler rods
- Gas (Oxy-Acetylene) Braze Welding – Purpose-built for gas welding processes
Recommended Applications
Comweld Comcoat C is the go-to maintenance rod for a wide range of braze welding jobs, including:
- Joining and repairing cast iron components (engine blocks, machine housings, brackets)
- Malleable iron repairs
- Steel fabrication and general repair welding
- Workshop maintenance where a versatile, reliable braze rod is essential
Note: This rod is not recommended for copper pipework carrying hot water or seawater, due to the risk of dezincification in bronze alloys. For those applications, a dedicated copper-based brazing alloy is more suitable.
