Crown Alloys Silicon Bronze Wire – ERCuSi-A – 0.030 in – 2 lb Spool | CSSIB/1E

Typical Applications

Crown Silicon Bronze contains 3% silicon and residual amounts of manganese, tin and zinc. The relatively high silicon content ensures that this alloy can be used for both welding and brazing processes. It is used for welding copper, copper-silicon, brass or bronze and for welding steel (primarily sheet metal) to itself or to the aforementioned alloys. Because of its relatively low melting temperature, Crown Silicon Bronze is well suited to weld (or “braze weld”) galvanized steels and other coated steels since it does not destroy the galvanized coating in the vicinity of the weld. The Crown Silicon Bronze weld metal is itself highly corrosion resistant thus retaining the corrosion protection of the original galvanized steel. The corrosion resistant feature makes this alloy ideal for surfacing parts that may be exposed to a corrosive environment.
