I got about 60lbs of truck wheelweights a while ago. These are from 35,000GVWR to 49,000GVWR trucks. The WW are huge compared to cars.
I melted them slowly this time so if there was any zinc, I could dish it out before ruining the entire melt. No problems with that. When I got it melted and cleaned, I tried casting a few bullets. Looks like it is not bad, but it will need a little tin to get it to fill out easily. I remelted them and dropped everything into ingots.
After it was all cooled off, I tested one of the ingots for hardness. It showed Bhn 17-18. I was surprised, so I tested two other ingots and got the same. That is a lot harder than any WW I have ever gotten before.
I am guessing it is higher in antimony. Any other ideas or experience with this kind of stuff?
