Lead wheel weights

Typical for a curb hunter or Dumpster diver , when you see you grab it, & don't stop till it's all in your truck.
Is that greed nope it's the rules of the hunt. But to be honest if I see others out I will let some things pass cause I do share .(not to say that about CU)

Ok I found I can get wheel weights from auto stations But as my intro stated thats where one has to calm down, See the stations will give you some @ 4 to 5 pounds but the whole bucket NOPE .
I see that some weights are pure steel
some are zinc and some Lead
problem I am having is
a few do say ZN or PB but many say nothing or say type A or MC I did see Mc-Zn
or the name of company like micro
Is it safe to say if it's not listed it's zinc or another factor I figure is simply Lead bends
and zinc is way hard to bend Or should I say lead snaps in half easy .
-----------------------
I am up to 50 lbs of Lead ingots (I made them) I have a mold for baking, I fill to top and you get a 4 lb bar
my next endeavor is I want to make a zinc bar same size for the reason to see the difference of Lead to Zinc at same size.
then pot metal these other metals are needed so if i ever need a compelling debate of my product i can show same size but weight truth.
-------
Just for the record 90% of my lead is from cast iron plumbing pipes and the soft lead from old toilet traps . 5% is from electric company stuff , 5% batteries
Wile I will use a bat. I will not let them dominate my mix for ethical reasons
