I think titanium is the only choice but I don't know about monel. The PCB holder in my tank was made using a titanium rod, since professional etching tank equipment is also made of titanium. ST

Titanium works fine with CuCl2 or FeCl. Most of the others won't though I have no experience with Monel. Les
