Tin melt temp?

[waco]

I have a bunch of babit I belive to have lots of tin in it.
My lee pot was about 3/4 full of Lyman #2, cold. I put a chunk of this babit on top and turned the pot on. Within a few minutes, the babit was liquid, while the hard ball was still solid. Does tin have a low melt temp, or is this possibly something else?

450degF

yes the tin melts much lower , i cast some 5 lb ingots of 90% tin seemed to take forever for them to solidify finally did @ 400 deg.

Sweet! Good to know.
A buddy that used to work in a saw mill gave me 44 lbs of this babit.

"gave me 44 lbs of this babit."

What a good friend you have there.

He is a great guy. He also gave me 220lbs of indoor range lead(.22 Lr) lead the same day.
Said he really had no use for it.

:cbpour: Does this friend need some more friends?

Depending on the specific type of babbit, the tin content can be as high as 87 %, it is usually something like 85-10-5 Tin, Antimony, Copper. Mix it at about 1-25 with your 22 boolit melt for some great casting alloy.

Today I melted down several bars of a Sn/Pb/Sb/Cu alloy that I had here, mostly to make them into an easier to use size, and also to blend them all together as the percentages were different between the bars. Some of them had almost 5% Cu (copper), some only .85, and I wanted to have a single alloy to use for sweetening my casting alloy. I threw them all in my dutch oven, and fired up the turkey fryer. Once they were all melted, I fluxed with some CFF (first time using it since I got it), and after fluxing the pot, I turned down the heat (mostly to save on propane), and started casting 1lb size ingots. When they cooled off, the first batch had several ingots that were copper colored on top, and for about the first 1/4" or so down as well. The ingots I cast on the second go around (I was using condiment cups, and only had 23 of them, but 50lbs of metal to cast, so it took a couple of fillings to finish) didn't seem to have this discoloration to them. Is what I'm seeing actually copper floating up to the top of the ingot? If so, does that mean that the second run of ingots has much less copper in them? The guy I bought these bars from has access to a Niton analyzer, and I mailed him one of these ingots, along with one of my home mixed Lyman #2, and he's going to check them for me to see what I really have! Sorry for the hijack, but my questions are tin related, so I didn't get too far off topic. :)

this is what the babit looks like
