DAIKOWT CuSn9

CuSn is used for welding a wide range of copper-based alloys, both with each other and with C-Mn steels or cast iron. It is also ideal for repair and joining of castings. When a low dilution is obtained, the material is suitable for overlays aimed at providing support surfaces and/or corrosion-resistant coatings on steel components, such as shafts and other mechanical parts. However, it is not suitable for stainless steels because the chromium released during the process can cause embrittlement. Tin bronze welding metal tends to stasis due to its wide melting range. Preheating to approximately 200 °C can improve fluidity in welding thick sections. To prevent hot cracking, it is advisable to keep the interpass temperature below 200 °C.
