Bismuth for home pour?

Recommended Posts

zenbasser, You posted a good question. I don't know that much about bismuth, but it's something to look into. Maybe some of the other guys have already checked it out. I looked on the web about it tonight and see where it says this about the stuff.

More Like Lead, But Legal

Bismuth is right next to lead on the periodic table. That means it?s nearly as dense as lead, and much heavier than steel. So if you liked lead, you?ll love Bismuth.*

Not sure what the melting requirements would be or if it would melt in my lead pot. Probably would but there again how is it compareable to the weight of lead.

Darn good question Zenbasser. Hope we get some insight from someone who knows more about it then I do. George

I don't know first hand, but I've done some reading. From what I've read, it melts easily over the stove (or in you lead pot). It's primarily used for shooting purposes. It's 86% denser then steel and lead is only 68% denser. That's just what I found out. I don't know what you pay for lead, but this seems pretty pricey, but I'm sure it would go a long way. Hope this helps.

I have poured quite a few lures using a lead alternative called Jewerly Casting metal or 92-8. It is made up of 98% tin and even some silver in the mix which gives it a bright shinny surface. This metal is lead free but even lighter than bismuth and no where near the price. It pours like lead but sets up a lot harder. Of couse you lure has to be probably 30% bigger to to make it the same weight as a lead lure. I ordered mine from Hallmark Metal Corp. http://www.hallmarkmetalscorp.com/ . Good people to work with.

I spin cast Bismuth/Tin alloy. It flows easier than lead, takes 4 times longer to set up and it melts around 300 degrees. Bismuth by itself melts at 500 degrees or so and so does Tin, mixed together they melt around 280 to 300. The Tin makes it lighter than the Bismuth but it flows better and breaks off smoother. When you break the Bismuth off, it leaves a rough edge. The Bismuth is more brittle, whereas the Tin is hard.

Bismuth doesn't seem to get rid of the heat like lead does. Bismuth expands as it cools, other metals shrink.

I have melted it in a Lee pot and poured in a Do-It mold, it is a little harder to break off. It snaps off, on lead you have to bend back and forth to break off. I said earlier that it takes longer to set up, but in an aluminum mold it sets up as fast as lead.

If you wanted to try some, I'd sell you some ingots. They weigh about a pound each. Just send me a e-mail.
