I haven’t done any casting in a while, mostly because it was a complete disaster the last time I tried. The issue I encountered was that I could never go fast enough with aluminum molds I have been using. They lose heat extremely rapidly and I’m new to this, so going fast isn’t something I’m really up to. Yet.
I want to give this another attempt and have read that brass loses heat slower than aluminum and iron loses it slower even than brass. I’m trying to decide between the two but having trouble gauging the differences.
I am not interested in a fast cadence. Ask it this way, is brass closer to iron in terms of heat loss or closer to aluminum? Is it more similar to iron’s slower pace or aluminum’s faster pace?
