Inweld Silicon Bronze, years ago referred to as “Everdur” 656, contains 3% silicon and residual amounts of manganese, tin and zinc. The high silicon content allows this alloy to be used in welding and brazing procedures. Silicon Bronze is best known for welding plain or galvanized steel sheet metal. Principal applications include MIG, TIG or oxyacetylene welding of copper, coppersilicon and copper-zinc base metals to themselves and to steel. Silicon Bronze is also used for surfacing parts that may be exposed to a corrosive environment. The weld deposits of this alloy demonstrate high strength, excellent corrosion resistance and good weld ability. Apply a high boric acid flux before and during welding. When oxyacetylene welding, the gas flame should be slightly oxidizing. Keep a small weld pool that promotes rapid solidification and this will also minimize cracking.
