Product Description
ECuSn-B (CuSn6 / UNS C51900 / CW452K) Tin Bronze Welding Rod / Wire
ECuSn-B (also known as CuSn6, UNS C51900, or CW452K) is a tin bronze welding rod/wire primarily used for welding tin bronze alloys, copper alloys, and dissimilar joints between copper alloys and steel.
With a controlled tin (Sn) content, this alloy provides excellent wear resistance, good corrosion resistance, and stable mechanical properties. It is well suited for applications requiring durability, low friction, and reliable weld performance in industrial environments.
Chemical Composition (Typical)
| Element | Content (%) |
|---|---|
| Copper (Cu) | Balance (~93-95) |
| Tin (Sn) | 5.0 - 7.0 |
| Zinc (Zn) | ≤ 1.0 |
| Lead (Pb) | ≤ 0.05 |
| Iron (Fe) | ≤ 0.5 |
| Others | ≤ 0.5 |
Note: Exact composition may vary slightly depending on manufacturing standard and application requirements.
