Hi Guys,
In a trade for some range brass, I got two 8" x 4" x 2" Blocks of, what the guy told me, are from a guy whose Father works in the Nuclear Medicine department of a local hospital. I have no idea what the stuff is but I know I can scratch it with my fingernail somewhat and it has that dark gray appearance of pure lead.
One of the blocks looks layered like it was in a mould and molten lead was added to it a number of times ( about 8 layers are discernible). The other block is a solid pour.
He told me he could probably get me more of these if I could use them.
I looked up the composition of " Large & Small Cores" on the Alloy calculator from CB site it it shows beside mostly lead there is some tin and antimony in those….. but I'm just not sure if it really is that stuff or not.
Any thoughts?
Thanks
Jim
