Copper-Nickel Filler for GTAW, 90-10??
(OP)
We are welding schedule 80 pipe. Alloy is 90-10 Copper Nickel. Commercial application. We have used Monel wire in the past. We were just told that the Monel is not the alloy of choice, lol. What alloy should I be using that is available for GTAW, Ø 1/16???

SFA 5.7
ERCuNi UNS C71580
I believe you can also purchase bare wire from Europe that closely matches the 90/10 Cu-Ni alloy;
SG CuNi10Fe
