So I made a bar took it to yard and they told me it is 50 50 zinc lead ??
so I am almost sure during some kinda transition wheel weights where also made as 50 50
some are Zinc
I am told Ammo people do put a little zinc in with the lead so the 50 50 might be desired
can any one help with whats up ?
From what I am reading 50 50 is great for larger calibers

What do they pay for wheel weights as is?

only pay .09 but a zinc bar is .20 lead bar .35 per pound
50 50 no go
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.Originally Posted by Copper Head

I have 148lbs of mixed wheel weights an have no idea what to do with them. Don't really feel like sorting them any ideas?

My opinion is based on my yard so there still may be a open door at another yard . First lead is .35 per pound and I remember that price for a few years now give or take . I also remember wheel weights used to pay better a few years ago and even 2 months ago it was .16 now it's down to .09
lead is fading away from the mix and the yards are responding with a pay out in there favor
steel weights are as good as short ZINC HAS MORE VALUE THEN SHORT AND LAST OF THE LEAD FLOATING AROUND IN THE MIX IS ICING ON THE CAKE.
If you separate you will have customers who need it for AMO but even my yard cares not , to them they are WW.
If you melt . I read that some people control the heat so only the lead melts and they skim off what floats to the top . That will be the steel & zinc.
That skim later can be melted to be zinc . Yet some Amo people have said that it's easy to make a mistake and melt zinc with it.
For me the good news is the lead weights are easy to find as they are soft and score with a cutter . also the sound is dull when let fall to a hard surface.
For me isolating the zinc is hard as I felt i did my best yet a tool at the yard picked up 50% lead ??? So who made the mistake Me or Them ???
All scrap is the same situation organized isolation of metal is the way to get top dollar .
I feel these are still the last days we can find lead zinc copper easy . Years from now the door will shut more and more . I see it clear
---------
the future less TV's to find
More electric motors AL
WW will be steel
We are urban minors and like any source, in time it is going to dry up ,and we best of all know the truth cause we see the replacement items . that the future scrapper will find.
Take advantage you can still sort

This is going to take some time
But are you saying if I have a bar of zinc and a bar of lead and each bar is same size the density can be measured with water displacement on the graduated scale ?
Interesting if some thing can be that sensitive
From what I have read there is a Zinc known to be pure
then a zinc known as (Good Ordinary Brand) that has about 2% lead
It's my hunch that NOW with lead laws getting strict WW saying ZN are proper
But if you study WW you will notice some have no letters telling you ZN
so I feel there are WW out from a few years ago that were made with Lead Zinc alloy as it was not a concern then.
I can confirm some ZN wheel weights are hard as rock and some wile not like lead are a little softer
only 5% Zinc is Ideal for Amo If the amo is going to be use fast. I have read amo with zinc does not age well ( but this is stuff from other forums so ....)_ . But as mentioned some large caliber Amo is very pleasing to shooters when it's a 50 50 mix
so zinc with lead will find a home with Amo people (some)
A complete separation of zinc from lead can be achieved by distillation

Yes, weigh your sample in grams then find out how much water is displaces in milliliters. Dividing your weight by your displacement will give you your density. I would think a postal scale with accuracy plus or minus 1 -2 grams, a container marked so that you can read volume to the milliliter and a sample of about 100 grams should give you a fairly accurate result.But are you saying if I have a bar of zinc and a bar of lead and each bar is same size the density can be measured with water displacement on the graduated scale ?

At work years ago a welding supply place accidently send us a handfull of 'Zinc sticks'.
I didn't know what they were, so I asked & was told
"Its a stick of low melting temp metals, mostly Zinc & Lead & tin. You make a arc weld & then before it cooled down, rub the stick onto the weld. The metal melts & sticks to the weld, giving it a galvanised Zinc surface coating.
Its handy for repairing galvanising thats oxidised from salt air & galvanising welds that will later on rust. Or fixing welds on galvanised metals."
zilt sticks, zinc repair sticks
Instructions from a site> Methods of use
If the item to be repaired has just come out of the galvanising bath and hence is still hot, the stick can simply be rubbed over the area required.
If the item is cold The method for there use is as follows:
Heat up the area of galvanising to be repaired ( take care not to exceed 200oC as this will damage the galvanised surface).
Heat up the end of the stick with blow torch or similar until the stick starts to melt.
Rub the end of the stick onto the area.
Re heat the stick and surface as required < end.
