What is this?

[montanamike]

I found a few pounds of these rods. There really soft. What got me was they aren't dull grey like lead gets. Hopefully they're lead free solder. Let me know. Here's a pic with a 200gr 45 swc for comparison.
Thanks

What did your bullet weight out at, could give you an idea of the lead 'rod' you have.

Honestly, how are we supposed to know? Get it analyzed somewhere. That is the only way you'll know.

That's a boolit for size comparison, not cast from the rod asked about.

I cast a boolit out of soww and one from the mystery metal. The soww weighed 207.6gr the rod bullet weighed 183.5gr. The rod boolitt poured a beautiful boolit the soww one i had to get waaay hotter and it still didnt fill out completely. Assuming it's only tin and lead it should be around 33% tin and 67% lead not bad for 75 cents a pound.

if it's high tin content it would be 'hard' to bend and would make a creaking popping sound when bent.
that's the tin nodules pulling apart.

just looking at it in the picture it doesn't look like a lead-tin alloy it's rough and crystalline white looking.

Probably some solder alloy? Sorry, my crystal ball is cloudy today.

Get is analyzed if you really want to know.

Looks like the bar solder we used to use in the flow solder machines a while ago.

Incase anyone stumbles across some of this it is pretty much 29/70 solder with 1% Antimony

That may be body lead solder for patch ing car bodies sheet metal. Many years ago before bondo and fiberglass rust holes were filled with lead and sanded down to finish. The bars came in about that form or shape. Filling in holes and damage with lead was accepted practice years ago.

[montanamike]

That's what I fugured they were. I took a small course on leading vehicle awhile back.

Imperfections in new bodies were also "lead filled". It's use was quiet an art form.
Race cars of that era were burned to rid the excess body weight.

Great!! I have about 90lbs of the stuff (just like your picture) -- often wondered what it was!! Real easy to bend -- I take it that the first number is lead and the 2nd number is tin?

[montanamike]

Sorry, first number is tin.
