babbitt metal

[uccm25]

I have some ingots of babbitt metal marked Avril Outlasta. Anyone know the comp. of this alloy? Have Googled with no luck.
Felix, please help.

My google foo (http://books.google.com/books?id=RzMOiOEQ-oMC&pg=PA151&lpg=PA151&dq=Avril+Outlasta&source=bl&ots=wMl87a8KUC&sig=GFu9QXl1nMBMVr34MlqLNs0mQPI&hl=en&sa=X&ei=F-anT8HMDIjg2gXHyI2mAg&sqi=2&ved=0CGcQ6AEwBQ#v=onepage&q=Avril%20Outlasta&f=false) turned up Avril Outlasta Babbit as 0.5 Cu, 15 Sb, 10 Sn, balance Pb.

This was from books.google.com's copy of Woldman's Engineering Alloys.

sqlbullet-
Thanks for the info and your time getting it. This is really hard stuff. Any ideas what to make with it as-is? Or I could do some computing and make some version of #2 I guess. Thanks

Copper based babbits are popular with the antique car and engine crowd. You might consider offering it to them and use the cash to buy lead.

Just now saw your request. Treat that babbit as pure tin in terms of amount to add to a pot and you should be fine with the composition as stated by SQLbullet. However, the antimony and tin ratios are good, actually excellent, and will make a very good old-time WW metal out of pure lead or the cheap WW we have these days. You would need to add a very small amount of 50-50 tin-lead as well to make a Lyman #2 out of your normal pot lead. ... felix

It is basically monotype with 1/2 a percent of copper added.

Good to mix with pure at 20/80 babbit/pure to get old time WW with high tin content (95/3/2 lead/antimony/tin).

Add just a bit, maybe 5/95 to modern COWW to boost it to the ratios of the old days.

Of course, lead is toxic. I will be glad to take it off your hands if you just want to be shed of it. I will even pay shipping :-)

Okay fellas, slow down. I'm trying to write this all down in my important book. There, got it. So, if I'm making a 20# pot, I could use 4#babbitt, 16# lead, and .5# 50/50 to make #2 alloy? Or do I need more 50/50? I've been making #2 alloy from 18# WW (old)(have good supply) and 2# 50/50, which seems to cast good. I have no idea of the hardness, haven't gone to the expense of a tester yet. Also have small supply of linotype for when my 50/50 runs out. Any recipes based on a 20# pot would be greatly appreciated. Thanks Felix for the info, and thanks sqlbullet for the info and the offer, but I don't give away the gifts God has given me. Lets talk more...

High velocity rifle bullets as is. It's very close to the babbitt I use for 2300-2400fps in my 1/8 twist 6x45. It should cast at 23bhn air cooled and will also respond to heat treating and water dropping. Target fun but too hard for hunting. 10% Sn makes for very pretty, well filled out, boolits. Surprisingly not overly brittle, thanks to the Cu, I would think. You can make a wide variety of alloys simply by varying the amount of pure added.

I understand the babbit is 10% tin, 15% antimony, 0.5% Copper, 74.5% lead.

Using your mix above:
4 lbs babbit + 16 lbs pure lead + 0.5 lbs 50/50 solder = alloy with 3.2% tin, 2.9% antimony, 0.1% copper, 93.8% lead

If you want to make Lyman #2 (5% tin, 5% antimony, 90% lead):
4 lbs babbit + 7.5 lbs pure lead + 0.375 lbs 50/50 solder = alloy with 5% tin, 5% antimony, 0.2% copper, 89.8% lead

[madsenshooter]

The OP's babbitt should make also a very good base to use for making a no longer available alloy, Ideal #1, which is 80%Pb, 10%Sn, 7%Sb, 3%Cu. That could be approximated with a little pure Pb, some Sn/Cu solder, and perhaps a smidge of Cu scrap. I'll leave the math to someone else, it was said to be a good high velocity hunting alloy, though I've yet to try it myself. I do have a couple heavy 30 caliber molds that would like to try it though.

Wow Bumpo! You must be a mathematical genius. That's some very good info and I thank you very much! Thanks also Madsenshooter for that info. I have a .243gc mold I may try it out on. I was into casting 30 or so years ago, but somehow lost my way. Now at 65 I've decided to get back in. This is a great website and you guys are the best!! Thanks, Guy.(my first name)
