Use & Application
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 100°C. 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.
