Product Detail

Shanghai Metal Corporation is a leading Silicon Bronze Welding Wire supplier and manufacturer.

Silicon bronze is the easiest type of copper alloy to be welded. Because of its lower thermal conductivity than other copper alloys, it does not require preheating before welding. It is a liquid metal with good fluidity and silicon also has a good deoxidizing effect ERCuSi-A Silicon Bronze is primarily used for TIG, Plasma and Oxy-Acetylene welding or brazing on Steel and Copper Alloys. A chemical analysis of Copper and Zinc as well as alloying elements of 3% Silicon and small amounts of Tin and Manganese produce welds with excellent mechanical properties. High strength, ductile and sound welds are easily attained by using a neutral or slightly oxidizing flame (especially on Copper Alloys). Keep the weld pool small to promote fast solidification and minimize cracking. Silicon bronze welding wire is usually used for welding copper-zinc alloys, stainless steel sheets and galvanized steel sheets, etc.
