Hello all, new guy here with a question maybe some of you can answer. A few years ago I came across what I believed to be lead wire while working one day. I picked it up with the intention of using it for casting. Just now I have got around to melting it down, but it doesn't want to melt! I had cut it into 6" strips and left it in my pot for plenty of time(ww were easily melted). A 1" section of this material floated in the alloy left in my pot.
The wire is elliptical in cross section, about 1/2" wide, and has a steel? wire core. It is mallable, but seems harder and tougher that lead. Also, since it seems to float in a pot of ww alloy it is lighter than that, but still pretty heavy.
Anyone ever come across this stuff or have an idea what it is?
