Use of Powdered Zinc, Duh! meant TIN

[Gray Fox]

Just had a Friday nite brain drain, I meant to say I have powdered tin, NOT zinc.

Did you actually mean powdered antimony? Tin should melt into the lead pretty easily. What temp is you melt at?

[runfiverun]

you gotta flux it in see my other post on your zinc Q.

[MtGun44]

Tin would melt right in. If it stays on top, it is something else.
Might want to find out what it is before you ruin a batch of alloy.

I dont know what we're talkin 'bout here Tin or antimony.

But Bill Ferguson (antimonyman.com) offers a self-fluxing lead antimony alloy product to enrich your wheelweight alloy that when introduced into the pot of wheel weight alloy will melt and allow the high melting point antimony to go into solution thanks to his flux he developed and the product is as hard as you would want EVER.


TIN is SO easy and so unnecessary (well you only need a half percent tin) cause it's function is as a surfactant to make molds fill out. Just get some tin-enriched solder and and add a few feet of it to your alloy. Tin does NOT contribute to HARDNESS, it is a surfactant.

I have two 1 lb ingots of pure tin and I have used one INCH of the metal for alloy manufacture in 11 years. I have abundant sources of Linotype (hee hee!) i ONLY use LINO for rifle casts .

If there is any arsenic or antimony in your mix the tin will form a complex with the antimony to aid in hardening the alloy. You dont need a lot of tin! 0.05%!
