Dear Expert,

Kindly advise the P No of the material 90/10 CuNi, UNS C70610 to BS 2871
I didn't find out from the table QW-422, ASME section 9.

Kindly advise and support. It is needed prior to PWPS preparation

There is none.

From my experience with 90/10, similar welds are done with the same filler. Dissimilar uses a nickel based alloy which may explain why there is no P number as copper and nickel are in separate groups.

Why aren't you brazing this?
