Economics and China

Copper is self sanitizing. Same reason some hospitals are starting to use copper door knobs and fixtures.

True. I think there are some plastics that can also be anti-microbial.

It probably comes down to price and availability of a pipe, fixture, or a door knob. I prefer metal fixtures, but then again I'm not all that ecologically focused sometimes in my more emotionally driven purchases, like water faucets. So, Feng yuck, who'd want a plastic water faucet?
