Lead?

[tmattox]

An older man came into our gun club today. He's a trucker hauling chemicals in tanker trucks. He's delving into casting (without supervision) . He said his company puts metal seals on the trucks to prevent theft of whatever chemicals they're carrying. He's melted a quantity of these seals (don't know the melting temp.) and asked me to see if they were safe to cast into boolits. I tried to get a reading on my Lee hardness tester but it wouldn't make a mark. Does anyone know what these seals are made of and should he use them for casting? Since I haven't gotten the hang of getting answers here, please email an answer @ tmattox69@yahoo.com.

I'd be willing to bet they are zinc

They are Zinc. How else would they allow these into CA?

Yeah, I believe they are zinc.

So, they're zinc, dedicate a pot and ladle and learn to paper patch :mrgreen:

If they are zinc, could he not get in contact with the gentleman that trades lead for zinc lb. for lb. to make cannonballs?

Put a drop of Muriatic acid on one and if it "fizzes" it is Zinc.
