my grandfather owned large scrap yard before he passed away there was a box of this metal in picture below i have no idea what it is .i tried few tests to try to figure it out .
1] burning it does melt with pocket torch and can flatten it
2] its hard and kind of heavy each little piece
3] not magnetic tested
4] cutting with wire cutters to test if was lead not as soft as lead
im really confused i have look at alot of metal in my time im stumped so any help will be greatly appreciated.thank you
