Wierd stuff...

[Fatdaddy]

I spoke to a friend earlier this week and we got to talking about casting boolits. He used to work in the medical field working with some sort of diagnostic equipment. Today he called me up and said he had some lead for me. Took me a detour on the way home from work and he produced a brick sized hunk of what looked like a lead ingot. Wasn't quiet as heavy as lead and dern hard stuff. I was hoping it was tin.
Heated up the old turkey fryer and before I could turn around I was looking at the prettiest silver melt you ever seen. I got my corn dodger mold out and started dippin'. After about 10 minutes and it was still liquid I got suspicious. Another 10 minutes and it's just starting to slushify. Finally I touched the mold and although it was hot, was almost holdable.
Another few minutes and I just had to stick my finger in it. "Almost" bearable!
Now for the question, What the hell is this stuff? It seems to have a melting point of about 150 degrees.
You think it would alloy with lead and be useable or is this the stuff they make Hot Wheel cars out of?

I'll check back later, I got to go run some cold water over my finger.:leaving:

Jes damn FD. :frown2:

You said he was in the medical field....... it's not from the liposuction machine, is it?!

There are a lot of bismuth alloys like cerrosafe that melt below the boiling point of water.

If it is cerro alloys are very expensive, I would NOT try to mix it with lead

You said he was in the medical field....... it's not from the liposuction machine, is it?!

Not sure, he said it was with some old equipment at an oncoloyg center he was changing out about 15 yrs ago.

There are a lot of bismuth alloys like cerrosafe that melt below the boiling point of water.

If it is cerro alloys are very expensive, I would try to mix it with lead


I may try that with a pound or two of lead just in case it makes a mess.
How much you think I should add to say 2lbs of ww ingots.

[jawjaboy]

Thankin da same thing Bro A. Had to shower. Sorry. Got a block a CerroSafe meself. Plannin on using it one day. Could be some a anything above FD. Save it. Guard it. Don't chunk it. :thumbsup:

Im sorry, I typed would and should have typed wouldnt:yikes:


I would NOT mix it with lead, if you dont want to use it get a better idea of the alloy and sell it, look at the prices I posted, that chit is expensive.

How many pounds do you have????

[layusn1]

Where is the this thread is worthless without pics smily?

[Fatdaddy]

Oh, forgot, the ingot had" something Medical 158" on it B4 the melt.
Maybe the melting point...?
If it is one of the Cerro alloys, what would be the negative effects of the Cadmium?

[yammerschooner]

That sounds exactly like the cerrosafe I have used.

[yammerschooner]

Just saw that this was already covered. I use cerrosafe for chamber casts. I have messed up, gotten it everywhere, and had to boil it out of a 700 action.

Any of you other gents ever boiled a firearm in water?

[jawjaboy]

Not that I a gent, but no I have'nt. Prolly will one day, given enough time. Tell da folk we say Howdy, they a understand, meybee. :wink5:

Parts...to remove cosmoline.

Passed along and howdy back.

BTW, their intention is to show up with a world class butt next time they are through. They have already been talking about the necessity of making it back to wherever the heck it is they go to in FL.

If they forget the butt be sure to give them a ration of crap from me.

Now all a dat ain't necessary. It be a lot a trouble keepin a butt on ice all dat way. Jes a good visit a make our day. Given ample notice, I a try ta round 'em up some S'paw. :cheers2:

I recieved a hunk of the mystery metal from Fatdaddy today.

Here is my semi-educated guess

""""
Cerrobend®, made by Cerro Metal Products, is also known as Wood's metal (http://www.answers.com/topic/wood-s-metal-1), Bend alloy, or pewtalloy. Or even Lipowitz Metal in Europe.
It is a eutectic fusible alloy (http://www.answers.com/topic/fusible-metal) of bismuth (http://www.answers.com/topic/bismuth), lead (http://www.answers.com/topic/lead-10), tin, and cadmium (http://www.answers.com/topic/cadmium), known for its low melting point of 70 °C (158 °F). Molten Cerrobend can be held in an unprotected hand (though not without considerable discomfort).
It is named for its primary use as a filler when bending thin-walled metal tubes. For this use the tubing is filled with molten Cerrobend. Once the Cerrobend hardens the tubing is bent, the filler preventing collapse of the tubing. The Cerrobend is then removed by heating, often by simply boiling in water.
Cerrobend also has uses for making custom-shaped apertures and blocks (e.g., electron-beam cutouts and lung blocks) for medical radiation treatment, and making metal inlays in wood."""""

[AdamN]

I should add the stuff is different than my Cerrosafe, its softer and melts at a much lower temp.

Also what Fatdaddy stated about it coming from the medical field would lead me to believe its Cerrobend.

Its about $28.00 a pound from Mcmaster, I would either keep it and use it as it was intended or try and sell it on EBAY as Cerrobend

[Fatdaddy]

Stuff was fun to play with till I found out about the cadmium content.
Did some reading on it....dangerous stuff.
I appreciate you looking at it ANeat, sounded like you had some insight on what it might have been.

[Fatdaddy]

I was bored Saturday and decided to play with some Cerro-stuff.
I took my KKM G20 conversion bbl and placed it in a padded vice while the Cerro was heating. By the time I plugged the bbl it was ready to pour.
It solidified in about 3 seconds and after about 10 minutes i knocked it out. It made a perfect cast of the chamber, feed ramp and bbl throat.
Pretty cool stuff.
