Call Ford? Look up the msds?
Take it to your scrap yard and see if they can xray it and tell you what it is. When you drop it on cement does it make a clang or a thud?
Do you have any more information on which engines used lead in their harmonic balancers?
Mallory metal is used primarily. Its a tungsten alloy with nickle and other metals. I doubt there is any lead in there.
It's a definite THUD when I drop them, and they do scratch a bit using my thumbnail. The man I got them from said his Father used them to cast 44 bullets, but he didn't know what the alloy might be.
Mallory metal is hard and shiny afaik. It's usually machined I thought. Mallory metal wouldn't need those sleeves in there, they press this stuff into crankshafts and TiG weld it to balance crankshafts with.
Stick a torch to the corner of one, if it melts like solder it's mainly lead, if it smokes greenish and whitish powdery smoke it is mainly zinc.
Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6° 30min chamfer?

If it makes a good thud instead of a clang and you can scratch it with your nail its probly faily soft lead.
