Stereotype, Linotype, and Clip-on Wheelweight Alloy Question

[Uncle Grinch]

I searched for alloy mixtures using stereotype, Linotype, and clip on wheel weights, but found nothing that answered my question.....

Trying to use these three ingredients to come up with a close #2 alloy for casting pistol and rifle boolits.
It's not that simple...at least for me. I have several hundred pounds of CCWW, almost as much linotype, and close to 100 pounds of stereotype bar ingot.

What ratio of each should I use to reach my goal?

Need something with a higher tin content to get #2 with those... 20# COWW to 5# Stereotype gets 1.6% tin, 5.2% antimony, 93% lead. Add .95#(heck 1# is close enough) of lead free 95/5(95% tin 5% antimony) and you come very close to #2 with 5.02% tin, 5.01% Antimony, 89.6% lead. Pewter would be a replacement for the solder, use 1 pound...

Here is some good info on type metals.

Thanks John, been reading that site for some time now. Lots of info, just not much on stereotype.

What do you need to know? Stereotype is 6%sn/14%sb/80%pb with a bhn of 23

Sorry. You want to make Lyman #2 using Stereotype. Gotcha!
Your probably going to need some pure to mix with the type metals.

Yeah.... trying to use stereotype as an alloy ingredient. Not having much luck. I suppose I can substitute it for monotype.

Very doable, just need a pound of something tin rich(95% or better)... rotometals has it, you can find solder and pewter in swap... this would make 26 pounds of alloy 20# COWW, 5# Stereotype and 1# of tin of some form so cost is not going to be sky high.

Now that does look doable. Any idea how close to #2 alloy it will make?

[MaryB]

#2 with 5.02% tin, 5.01% Antimony, 89.6% lead. Pewter would be a replacement for the solder, use 1 pound. Basically #2!

Bumpo's lead alloy calc. will tell you what you need.

[MaryB]

Yup Popper, that is how I came up with those percentages!

Going to have to go back to using my desktop computer as this iPad thing doesn't seem to like excel. I'll give it a try tonight after things settle down. Still cleaning up downed trees from Irma. Got two more to haul off today.

Thanks for the info!

How reliable are your known alloys? I've used all kinds of "type" alloys and wheelweights and found them to be very variable. If you want to arrive at a specific alloy from another I would first do some physical testing on the known alloy, that is; solidus/liquidus temp., density compared to pure lead and BHN as cast and a week out. Compare these results to known data for various alloys to establish where this alloy likely falls then do an admixture calculation to make the alloy you want. You will probably need to add tin, I buy ingots of tin from Rotometals. It's expensive but you only need 2% for castability. The LASC pages are a big help, some of the most reliable data I've found...Good luck!
