Copper and Nickel banned in the USA?
Have you got prrof of this?
Have they banned everything containing Copper or Nickel ?
It's all in the nuance of course but, as Americans are keen on copper guttering and common coinage the world over uses copper nickel alloys then no, copper and nickel are clearly not banned in the states. I'm sure stainless steels are popular over the pond too.
As far as my knowledge goes with this stuff; it's used offshore on fire water systems because barnacles and crustations don't or can't latch on to it and so it's a prefered material for that most important of tasks.
I don't want to be a rumour monger but this mix is not good. I'd heard the Scandinavians had kicked it out too but again, hearsay.
I tested out on CuNiFer in the mid nineties and we were scared of it then (and my comments stem from that time) but then, I was told white asbestos was ok in the late eighties, it was the blue and brown stuff that was bad. Go figure.
