Silicon Bronze is a copper base welding alloy used in MIG and TIG applications but can also be oxyfuel welded. Commonly known by the name “Sil Bronze” and “Everdur 656”, this alloy is a popular choice in automotive shops.

APPLICATIONS

XTR Silicon Bronze is typically used to join and overlay welding of copper zinc alloys, low copper materials and through galvanized sheet steel, also for an excellent option for overlay welding on low and unalloyed steel as well as cast iron. Corrosion resistance is good and therefore is suitable for surfacing in some corrosive applications. For MIG overlay welding of large work pieces preheating is recommended and is best practice to keep your weld pool small to minimize cracking issues post weld. For multilayer welding on steels, pulsed arc welding is recommended.
