Description
Washington Alloy Silicon Bronze ERCuSi-A MIG Welding Wire 2 lb. Spool
2 lb. Spool – Washington Alloy Silicon Bronze MIG welding wire is a copper-based alloy containing about 3% silicon and may have small percentages of manganese, tin, and zinc. It is typically used for the MIG welding of copper, brass, bronze, steel, galvanized steels and also cast iron. Available in .030, .035, and .045 diameters.
Preheat: When working with silicon bronze base metal, keep the interpass temperature below 150 F to minimize hot cracking. Base metals of cast iron may need a preheat of 600 F while copper may need a 400-800 F. The use of a small narrow weld puddle will reduce the contraction stresses and give you a faster cooling during the hot-short temperature range.
Shielding Gas:
- Argon 100%
