brass is what you use. from what I'm told u work it like lead to smooth out the welds or whatever else you're wanting to smooth. it doesn't have to be a metal that can be magnetized, it just needs to be able to conduct a sufficient electrical charge. I don't think lead would work because, although a metal, lead is a poor conductor as compared to other metals such as copper, steel, brass, aluminum, etc...
