Yep, stung again by an Amazon supplier. Advertised as 0.3mm Stainless Steel Wire. Absolutely not, as you can see. Some plated copper muck:
So three spools of that can go in the bin. My first clue was that it started copper-plating the spoon, er, cathode in my electrolysis setup:
FYI I was using 1% nitric acid rather than my usual salt water. I intended to see if that would stop the production of cloudy iron hydroxide so I could tell when the end fell off the etched probe more easily. Turns out I need to try a different batch of wire, huh?
My sympathies. Not long ago I bought some expensive, super thin, Nitinol wire for some experiments, turns out the stuff they sold me was not prepared to "remember" anything.
ReplyDeleteOn the plus side, you've invented a very expensive way to manufacture copper plated spoons.
ReplyDeleteThere may be practical applications if I ever lay hold of conductive resin.
