Hello, I'm pretty new at this metal casting world... I would like to know if instead of using tin I can use aluminium and would the mixing percentage the same (88 to 12)? Thank you very much!
Hello, I'm pretty new at this metal casting world... I would like to know if instead of using tin I can use aluminium and would the mixing percentage the same (88 to 12)? Another doubt I have is about the use of borax in the molten metal... is it necessary? what is it for?! Thank you very much and pardon my ignorance!
I believe what the books were referring to was dissolved gasses in the metal. When you melt any metal, a certain amount of air will dissolve into it, which can be a problem when pouring as the metal cools, the gas comes out of solution, and the metal bubbles. That being said, I haven't actually had any trouble with it in my projects, so I believe the heat exchanging benefits and the extra alloying time (It actually seems to create a more uniform alloy, in my experience) justify putting the tin in the bottom of the crucible. You do definitely have a point, though, and I'll beef up the alloying section with this information and possible alternative ways of doing it. Thank you!
I'll look for a different tutorial and make a few edits with this in mind. Thank you!
