ERCu Spools Deox Copper Welding Wire Blue Demon

ERCu (Deoxidized Copper) is a filler metal
containing 98% or more copper with small
amounts of Phosphorus and Silicon used for
joining copper to itself or with galvanized or
mild steel where high strength joints are not required.
This easy flowing alloy produces weld
deposits that match the color of copper, are
electrically conductive and porosity free.

Applications
• Joining copper pipes, tanks, and copper fittings
• Joining deoxidized copper
• Overlaying steel surfaces to resist corrosion
