简要说明：CLASSIFICATIONS: ERCuNi AWS A5.7 ASME SFA 5.7 UNS C71580

ERCuNi is formulat-ed for the welding of 70/30,80/20 and 90/10 copper-nickel alloys.The weld
metal provides outstanding corrosion resistance,particularly against ses water.
CLASSIFICATIONS:
ERCuNi

APPROVALS:
MIL-E-21526
MIL-EN/RN67
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.
