Red Metal Alloys

Deoxidized Copper is a filler metal containing 98% copper and small amounts of phosphorus and silicon. The C189 alloy is easy flowing and produces weld deposits that are porosity free, electrically conductive, and copper-color matched. C189 is used to repair weld copper castings, to weld galvanized steel and deoxidized copper to mild steel where high strength joints are not required. (Specification AWS A5.7 / ASME SFA 5.7 Class ERCu)

Deoxidized Copper (C189) ERCu

Silicon Bronze (may also be known as Everdur) is a copper-based filler metal containing about 3% silicon and may have small percentages of manganese, tin, and zinc. C656 is typically used for gas-tungsten arc welding and gas-metal arc welding of copper, brass, bronze, steel, galvanized steels and also cast iron. It is also used for surfacing areas that are subjected to corrosion. (Specification AWS S5.7 / ASME SFA 5.7 Class ERCuSi-A)
