CuSi

Silicon bronze 97CuSi stands out for its versatility, offering a wide array of applications beyond those covered by DAIKO CuSn. Its utility spans overlaying steels and cast irons, making it a preferred choice for various needs. Applications range from plates used in chemical plants and molds to stills, calorifiers, rods, and wires for electrical components. The alloy also finds its place in tubes for heat exchangers. Notably, when working with silicon bronze, the convenience of not requiring preheating adds to its appeal. It's recommended to maintain an interpass temperature below 100°C. However, if welding copper, a preheat of around 100°C for 6mm material is essential, rising to approximately 400/500°C for thicker materials of about 15mm.
