ERCuSi A Silicon Bronze Rod is a copper-based filler metal containing 3% silicon and small amounts of manganese, tin, and zinc. Primarily used for MIG, TIG and oxyacetylene welding of copper, copper silicon and copper-zinc base metals to themselves and to steel. Excellent for plain~or galvanized steel sheet metal as well as other coated steels. Alloy Silicon Bronze is also used for surfacing areas subjected to corrosion. The oxyacetylene gas flame should be slightly oxidizing. Keep the weld puddle small in order to promote fast solidification and minimize cracking.
