Mel, In the table you mentioned from AWWA research foundation, does it include the ppm of ammonia threshold for SCC in 90-10 Cu-Ni?  In addition, does anyone have data on the cracking initiation time of 90-10 Cu-Ni? There are some data on other copper alloys, but I couldn't find any for Cu-Ni.  Thanks, ...
