50/50 bar solder ?

[gunslinger20]

Is 50/50 bar solder pb to tin or antimony? I want to alloy WW + pb + ? = 10 lb Lyman #2 with that formula i can make any amount i want.
Thanks in advance.

No, it's tin to lead. So a 1# bar of 50/50 is 8oz of tin, no antimony at all.

Thanks Fred

You can't make Lyman number 2 from WW and solder. You need to find additional antimony somewhere. Typical source is type metal.

9 pounds of WW plus one pound of 50/50 will give you ~92Pb-3Sb-5Sn. That's about as close as you can come with what you have on hand.

With that formula can you give an estamat of bhn?

You could probably expect about a 12. Unless you are deadset on expansion control , I would suggest less tin. Higher tin alloys actually soften with age.

I think lots of reloaders are useing 50/50 ww/pb but I dont understan why they arent having size problems.

Lyman #2 is 5% Tin, 5% Antimony, Hardness = 15 Bhn

You could add Magnum shot (5% Antimony) and 50/50 solder to get very close to Lyman #2.
9 lbs Magnum shot + 1 lb 50/50 solder = 10 lbs of 5% Tin, 4.5% Antimony, Hardness @ 14

Rotometals has a formula for estimating hardness:
Brinell = 8.60 + ( 0.29 * Tin ) + ( 0.92 * Antimony )

Let me know if you want a copy of my alloy spreadsheet.

yes that would be very helpful I have some #2 lead shot from years ago when I used to goose hunt, I dont know if that is magnum shot.

thats what the Lyman
manual said as well
9# ww and .5#lead,.5#tin
or if you will 1# 50/50 rite around 15 bhn

Wow too much to take in all at one time, very informative.Ill have a lot of options that I didnt know existed, Thanks

Or, you could get three things for two dollars and one thing for four dollars...
