Guten Tag! My Deutsch is a bit rusty, but I think there was an error in translation. Instead of using my telephone with it I think the translator program meant to say you found out. I also think you meant that as a statement rather than a question. Aren’t translators wonderful? I am not finding any paramagnetic element which fits the data. All the paramagnetic elements I checked are either too hard, to dense, too reactive with air or water, too light, or don’t occur naturally in the elemental state. It is possible it has impurities, as elemental iron and iron (III) are paramagnetic. Now, if you meant to say it is weakly magnetic rather than paramagnetic, then galena can be weakly magnetic due to iron ore impurities. Link to comment Share on other sites More sharing options...
Geologyhound Posted October 8, 2023 Share Posted October 8, 2023 OK, that density changes the equation a bit. Checking… Link to comment Share on other sites More sharing options...
Geologyhound Posted October 8, 2023 Share Posted October 8, 2023 Aluminum is paramagnetic and has a density of 2.7 g/cm3. Link to comment Share on other sites More sharing options...

If you did the specific gravity test accurately then yes - it's almost certainly aluminum. Streak color matches too. Probably some melted piece of some junk that got water tumbled/worn later.

BigSkyGuy Posted October 8, 2023 Share Posted October 8, 2023 I find aluminum "nuggets" all the time on fresh water beaches. People build a campfire on the beach and throw in beer cans, pulls tabs, etc. which melt into nuggets. Link to comment Share on other sites More sharing options...
