Help with Tin and Antimony, and others.

[Bazoo]

Im working on a project, and I need to know the BHN of tin and antimony.

I also need some others. Does anyone have info on the BHN of any of these that they can source, of if you know where I can find this information. The tin and antimony are the most important for me. Thanks all for helping.

What I've tried so far is, calling rotometals, googling, researching through google. Anyone have suggestions on where else I can source this information?

lead/tin

40/60 Solder', bhn: nil,
50/50 Solder', bhn: nil,
60/40 Solder', bhn: 16
63/37 Solder', bhn: nil,
95/5 Lead Free Solder', bhn: nil,
Antimonial Lead', bhn: nil,
Chilled Shot', bhn: nil,
Magnum Shot', bhn: nil,
Regular Shot', ​ bhn: nil,
Pewter', bhn: nil,
Pure Tin', bhn: 9.5
Zinc', bhn: nil,

Have you tried the spread sheet in the stickies at the top of the forum?

[Bazoo]

Yes, thank you for that suggestions.

I want to verify that info, because im making an alloy calculator, and I want to have verified values.

Interesting reading, but you may want to skip to pg 1093

I have cast bullets for a long time but still do not know terminology. When I have my lead mixed up, I add in Beeswax and torch the flame. I then scrape off a black residue, what is this called? I then put in some "Marvelux" that forms a crusty residue on top and remove it. What is that called and what did it remove? I then feel my lead is O.K. to cast with. Any help or input is appreciated.

The act if fluxing the crust is dross

[shooter bob]

Bazoo I believe Lyman cast bullet handbook #4 has a page with bhn values .I will try and find a page number

The act if fluxing the crust is dross

I believe dross is a noun not a verb. Dross is what the act of fluxing removes.

I regretfully sold my 4th edition a while back. I should pick another one up at some point.

I just looked through my #4 and couldn’t find anything.

Fluxing cleans the alloy surface in either or both of two ways. First it can reduce (the reverse of oxidation) the oxides returning them to base metals and second it can act as a "getter" combining with contaminants to make them easier to physically remove them in the form of dross.

Hot alloy in the pot will oxidize on the surface because it is exposed to air. This can't be avoided if you are casting using a dipper but if you are using a bottom pour pot you can leave a layer of dross or flux on the surface to protect the surface from contact with air.
