Elemental Metals
Here are several 1oz samples of pure elemental metals. I tried to get a nice variety - bars, rounds, and hand-poured ingots.
Top: copper, zinc, nickel
Middle: indium, bismuth, lead
Bottom: tin, silver, titanium
I have a very large magnet that I used on these. The nickel is very ferromagnetic. Most of the others are diamagnetic, with copper and silver producing the strongest response. Lead and bismuth have the weakest response. Titanium is very slightly paramagnetic, but it's hard to tell.
The copper and silver I've had for a while, and they show some oxidization. The rest are new arrivals from eBay. Indium was the most expensive, followed by silver. The rest were all under $8 each. I have a 1oz bar of pure iron on the way, and plan to pick up some others.
I have samples of tungsten and gallium as well, but not 1oz samples.
