A mavis teck and another tire teck confirmed yes some factory weights were 50 50 Lead Zinc
the codes i am trying to figure are Mc - Zn or P - Zn some just say ZN
Or could it be that i used the same mold that was used with lead so I got a false read
My first batch started out as 4.5 pounds and not one was soft and could not be crimped , it also took longer to melt
go figure
cant get one reference on the net to the 50 50 so who knows
gota be a false read

The density of lead is 11.34 grams per cubic centimeter or milliliter. Zinc is 7.14 grams per cubic centimeter. With a graduated cylinder, scale and a calculator you can quickly get a pretty good idea of what you have.
