What this rod is and who uses it

This ERCuSi-A silicon-bronze TIG rod joins copper, copper-silicon and copper-zinc alloys. It is supplied in 36-inch lengths at 3/32 inch diameter and packaged as a 1 lb tube. The rod suits fabricators and repair technicians who need a silicon-bronze filler for dissimilar copper-base metals.

Installation notes and common pitfalls

The rod is ready for TIG (GTAW) use with no additional preparation beyond standard cleaning of the base metal. Common issues include insufficient shielding gas coverage leading to porosity and overheating the thin 0.0938 inch rod, which can cause premature melting before the puddle forms.

Capacity and where it runs out

Each 1 lb package contains multiple 36-inch rods rated at 50 ksi tensile strength as welded. The alloy handles copper-to-copper, copper-to-brass and brass-to-brass joints. It is not intended for structural steel, aluminium or high-stress load-bearing applications where a higher-strength filler is required.

Questions about this item

How can I verify the rod is performing correctly after I start welding?

Check that the bead shows good fusion on copper or copper-silicon joints and that the tensile strength of the deposit reaches the rated 50 ksi value.

What comes in the package and what must I supply separately?

The box contains 1 lb of 36 in ERCuSi-A rods at 0.0938 in diameter; you will need a compatible TIG torch, shielding gas and power source.

Which diameter and length should I choose for copper-to-copper work?

The 3/32 in diameter by 36 in length is the only size offered and is suited for copper, copper-silicon and copper-zinc base metals.
