Identification Help Needed

Brass hammers are also used for non sparking when working around flammables. I use a small one on my lathe and mini mill to tap parts into place without damaging them and to pop out colets etc.

Give it a tiny scratch and see what color the metal it or are you scared? heheh

5) From its reaction to a file, it is a relatively soft, white metal.

Also in the original post I mentioned that its specific gravity is about 6.2.  The common copper alloys (common brasses and common bronzes) have s.g.'s close to 9.

IMO Carl is on the right track when he says 'pot metal'.  I think that is a broad spectrum of alloys, all of which are easy to melt and not very robust.  Pot metal often contains zinc, although that's another element which has density up there with copper, around 9.  But alloys don't necessarily reflect the densities of their constituent elements, and there are a few low density elemental metals (like aluminum and magnesium) which might be tossed in the pot.

We've pretty much beaten this topic to death (with a hammer ).
