3 lb. tube 36 inch lengths - Harris Siliicon Bronze TIG welding wire is a copper-silicon alloy used to weld similar composition base metals, brass, and
to weld these copper alloys to steel. Silicon bronze is also frequently used in GTAW
“brass welding” of coated sheet steels.
Preheat: Silicon bronze base metals generally do not require preheat. Brass or
copper base metals may require some preheat depending on copper content and

what is the chemical composition of this welding wire? Equivalent UNS number or similar?
Thank You. Mark
The manufacturer Harris Products advises that the UNS # for Harris ERCuSi-A Silicon Bronze TIG Welding Wire 3# is UNS-62000.. The chemical composition is shown below
Manganese 1.5 % max. Tin 1.0 % max.
Lead 0.02 % max. Zinc 1.0 % max.
Copper Remainder Iron 0.50 % max
Silicon 2.8-4.0 % Aluminum 0.01 % max.
Others 0.50 % max.
Used for welding some bronze sailboat hardware together, flowed and wet in nicely, perfect color match. I have also used for tig "brazing" on mild steel and thin stainless and it works very well for that.
How well the wire flows with low heat.

Have not used it very extensively, to the point where I can comment

This is a great rod for light welding (brazing) and looks good too.
