CuSi

The silicon bronze 97CuSi offers superior versatility compared to DAIKO CuSn for various industrial applications. It is ideal for overlaying on steels and cast irons, making it perfect for the fabrication of plates for chemical plants, as well as molds, distillers, radiators, rods and wires for electrical components, and tubes used in heat exchangers. Preheating is not required when welding silicon bronze; it is crucial to maintain the interpass temperature below 100 °C. For copper welding, preheating is necessary: approximately 100 °C for materials with a thickness of 6 mm, rising to 400-500 °C for thicknesses of 15 mm.

Pure copper deoxidized with 3% silicon.

Single phase (fcc).

General purpose including phosphorus deoxidized copper, silicon bronze, nickel silver, and some brasses.
