    Another vote of appreciation!
    It shows me I can cut back on the added tin from 2% to 1%, and that's good news.

    Al. designates a weight that is safe to use on aluminum wheels and is either coated or of an alloy that will not corrode the wheel.

    I'll give you A for effort, but there is a problem with your testing... The MC/AL/P/AWN/EN/TN etc... are the types of wheels they fit, not the manufacturer. I have a chart on my balancer. I think BADA makes/made most of them, at least the new ones I have.

    Thanks. I would appreciate knowing how to match each type to the manufacturer. Either way, I sorted and grouped them by the label I could find on the weight. I added two more tonight.

    richbug is correct, the two letter code that you are sorting by is just the indicator for the rim type that the coww fits. There really are only three major producers of wheel weights in the USA, BADA is the largest, Perfect Equipment , and the third escapes me at the moment.

    Thank you for this!!

    Your research REALLY puts paid to all the people who say they NEED 92/6/2 Hardball alloy for 45 auto or other low velocity/low pressure loads...when we've been using straight clip WW the whole time which are roughly 97% lead, 2% antimony and 1% tin.

    Next time cast bullet makers insist you need Hardball and 16 BHN for your pistol bullets, remember this study when you get leading.
    Due to market fluctuations I am no longer buying range scrap jackets.

    I think he was filling in the third one, but he wasn't sure, hence the question mark!

    # MICRO?
    *****************

    The third company is PLOMBCO.
    Yeah, that is why he put a "?". He was guessing!

    Micro is made by BADA. The third company is PLOMBCO.

    I think that you will find that the formula changes very often due to the fact that the requirements for COWW is not very difficult. I would bet that raw materials are always out for bids, and the formula changes slightly each time raw materials are purchased. My guess would be that most COWW are made from recycled materials to begin with, which will constantly move the formula around.
    Don't know any of this for a fact, but that is exactly what was done in the factory that I used to work for.

    I would also like to nominate this thread for stickie status. This is information we can all use. Especially when it is completed.

    Where did you get the analysis done at? What was the cost?

    Thx!

    Correct, I also have all of these NEW at work, I also, and for the most part use "I7" and "TAL" TRUCK wheel weights!, we use the "Perfect" brand at work.

    Since one might typically melt a fairly large batch of COWW I am looking forward to finding out a combined average from all the different sets. Figure a hundred pound batch should follow the the composite average pretty well.

    I have access to several XrFs at work. The cos is just my time. I am very careful to not test during normal work hours or to get in the way of the off shifts. My boss is fully aware of me using the machines for a "government project" and I intend to not abuse this privilege. Between business being good and some travelling my time is limited. I hope to get another group in this week.

    If your thinking of maybe having your lead assayed this is what I found looking for XrF services. I have yet to use them but will be sending my Lino/Mono/Foundry alloy in for a break down of material make up.

    Have to commend BNE for the excellent post and information!

    If we look at the average of the 4 different makes (how many of us really separate COWWs by make?), since most of us just smelt 'em down as they come out of the bucket, we see the average content of tin is .71% and the average content of antimony is 2.85%. I we add 2% tin as I always suggest we have 2.71% tin and 2.85% antimony. That is almost a perfect balance for the tin and antimony to mix as SbSn. That then mixes perfectly in solution (refer to the "Metallurgy" articles in Lyman's' CBHs).No wonder it turns out to be such an excellent alloy for fillout and hardness that is actually very close to Lyman's #2 alloy in performance.

    Thanks again BNE.
