Making Bronze part 2
Hello, I'm helping a small company in Guatemala pick up a bronze founding project that they were trained in by a professional foundry worker about a year ago, although I have little experience myself. We are casting micro hydro turbines blades out of bronze and although following the same instructions as last time, we've managed to ruin the (expensive ) bronze that we bought by ... I think oxidizing all the tin and lead out of it. I've read the last thread (letter 17977) on making bronze by melting it and adding the elements in their correct percents. I was just wondering if just mixing it like a soup is sufficient to make bronze, or are there other treatments like quenching and tempering and cooling a certain way that have to be done to obtain a good structure.
thanks.
