I have a lot of Wheel Weight in pails (about 3,000 Lbs.) and mixed with it is a lot of the flat stick-on weights.  I seperate this from the other and am wondering if it's pure lead?   How can I tell?;} Thanks, Gary

Stick-on Wheel-weight is nearly pure lead with less than 1% trace elements, you can easily scratch stick-on with a fingernail and see that it scratches easier than Clip-on Wheel-weights.

It is good to keep it separate as stick-on can be used the same as pure lead in formulas for bullet alloys. Stick-on is also excellent just by itself for casting muzzle loading round balls and muzzle loading bullets that call for pure lead. Stick-on will have a BHN hardness very close to pure lead and usually tests at BHN 6. 

You can verify hardness with a hardness test kit. I use the Lee Hardness Test Kit:

Gary is correct, at least as my testing shows. About 1% scrap metal and the rest lead. The only reason is that these are pressure extruded, and anything harder doesn't work well and costs to much to replace dies.

There is a lot of good information being shared out there if you just take the time to look around.  This link might help with your question on Wheel Weights of all types.

Might even keep you from adding zinc to your pot.

3000 lbs of lead... now that is just teasing us isn't it?

It depends what style SOWW you have. Some are nearly identical to COWW. This member BNE and myself have done more testing of wheel weight alloys than just about anybody (I think) because we both have access to XRF testing equipment.

I have handled the COWW, and BNE has done extensive testing of the SOWW. He tested each configuration and posted the results on CB forum.

Nowadays there are a lot more zinc and steel tape weights.

Use pliers if you're not sure, the lead deforms very easily and the zinc/steel ones are obviously much harder. Or use the drop test, the iznc and steel ones have a distinct ring or 'tink' and the lead ones just 'thunk'. But yes, the lead stick-ons are nearly pure lead as opposed to the normal lead WW alloy

Using BNE's chart, I separated the stick on wheel weights. The one's shown as having 3% antimony with his XrF gun were separated from the rest of the lead stick one's. The ones separated definitely “clinked” when dropped on concrete. The rest were more like pure lead and “thunked” on the concrete.
