| CLASSIFICATIONS: |
| ERCuNi |
| AWS A5.7 |
| ASME SFA 5.7 |
| UNS C71580 |
| |
| APPROVALS: |
| MIL-E-21526 |

| |
| APPLICATIONS: |
| Dissimilar welding applications for Arcos 813 include joining nickel-copper alloys and Nickel |
| 200 to copper-nickel alloys.The exceptional resistance to corrosion in sea water makes |
| ERCuNi the ideal choice for welding in offshore constuction and desalination and marine |
| environments. |
