ECuSi-B (also known as CuSi3, UNS C65500, or CW102C) is a copper-silicon alloy welding rod/wire designed for welding copper alloys, silicon bronze, and dissimilar joints between copper alloys and carbon steel or stainless steel.
This alloy features excellent fluidity, low crack sensitivity, and good corrosion resistance, producing smooth and clean weld beads.
It is widely used in automotive parts, mechanical components, piping systems, and general industrial fabrication.
