melting old trophies
hi group:
Just purchased a box of busted up trophies - all made in China. I tried to melt one with a propane torch which would usually melt zinc very easily. The trophy would not melt - just turn pasty - and not flowable at all- and impossible to separate any scum out with a liquid button. This metal is pure junk for casting -- or can it be saved with some type of flux - or possibly a 50% mix with clean new zinc added. It would be nice to be able to use this stuff for pour casting as there is a lot more available, but as it looks like --this metal was possibly pressure cast in China with a cheaper mix of metal alloy ... as it looks black on a cold break as compared to silver with pure zinc. Can it be saved? |
I'm not sure about how useful they are, but you can get boxes of them for
free here in the NE. Any trophy store will usually have them lying around or have people walking in with them asking, "Can you use these?" -- Regards, Joe Agro, Jr. (800) 871-5022 (908) 542-0244 http://www.AutoDrill.com http://www.Multi-Drill.com V8013-R "Danny G." wrote in message ... hi group: Just purchased a box of busted up trophies - all made in China.
