Copper has bounced and is back on the rise. From a low of $2.40 a few weeks ago, it’s gone back up to $3. It’s still a whole lot better than the $4 it hit a while back, but not nearly low enough or stable enough for metal stampers to specify it reliably.
Zinc, having hit $2, is down to $1.45, but there was a short run up a few weeks ago.
Nickel, which was $3 5 years ago, is now $22, more than 5 times the price of 5 years ago and shows no sign of slowing down.
