Silicon Bronze Tig Sheet Metal

Silicon bronze is a copper alloy rod containing 3 silicon and used for tig or oxyacetylene welding of copper brass bronze steel and cast iron.

Silicon bronze tig sheet metal.

While er70s 2 filler metal is a common choice for steel another popular option for welding sheet metal is silicon bronze. It can also be used for surfacing areas subjected to corrosion. It is softer and finishes well while reducing the heat required to weld it. It s nice for sheet metal work because the lower melting temps means less heat which equals less warping when compared to tig with say an er70 rod.

It s also important to select a filler metal that is thinner than the base metal or as close as possible. While the melting point of steel is around 2700 f. The silicon bronze rod s lower melting point makes it ideal for joining together thin sheet metal galvanized steel and nuts and bolts too. The melting point of silicon bronze tig rod is between 1800 and 1990 f.

Silicon bronze is a copper based filler metal primarily used for mig tig and oxyacetylene welding of copper copper silicon and copper zinc base metals to themselves and to steel. Silicon bronze is best known for welding plain or galvanized steel sheet metal in the manufacturing of steel cabinets metal furniture and ductwork. A chemical analysis of copper and zinc as well as alloying elements of 3 silicon and small amounts of tin and manganese produce welds with excellent mechanical properties. Silicon bronze can be used for on plain or galvanized steel sheet metal.

Tig welding with silicon bronze is technically tig brazing because usually the base metal being welded brazed has a much higher melting point than silicon bronze filler rod. Silicon bronze filler metal is made up of mostly copper with 2 8 4 silicon and and trace amounts of manganese tin and zinc that lower the melting point to around 1900f.
