I picked up some bar scraps from an estate sale today ($20 for some big chunks of Al and brass!), and I'm trying to figure out what it all is.
Some of the Al round bars are marks 24S. This looks like an aircraft Al alloy, but how is it for home machining, compare to, say, 7075?
There are also a couple of Al rods about 3/4" in diameter which have a darker gray skin, and, judging by the machined ends, cut very nicely. Any ideas on how to identify the alloy?
I also picked up a piece of brass (or bronze?), 1 3/8 diameter, with "Bunting", Made in USA, Toledo Ohio on it, and another larger hunk of brass. Any hints on identifying the alloy?
Thanks!
