97CuSi silicon bronze has a wider range of general
purpose applications than DAIKO CuSn, including overlaying
of steels and cast irons.
Applications include plate for chemical plant and
molds, stills and calorifiers, rods and wires for
electrical components and tubes for heat exchangers. Preheat is not required when welding silicon bronze
and interpass temperature should be kept below
If welding copper then preheat of about 100°C will
be required for 6mm material increasing up to about
400/500°C for 15mm thick material.
Pure copper deoxidized with 3% silicon.
Single phase (fcc).
Materials to be welded
General purpose including phosphorus deoxidized
copper, silicon bronze, nickel silver and some brasses.
