Composition of JS Brass

Does anyone out there remember having worked with a casting grain
called JS Brass? We originally purchased it through Swest which is
now owned by Stuller. We are trying to get the info on the contents,
one person remembers that it contained some gold in the mix which
made it 4K. If so, we plan to have it refined, if not, it would
there would be no reason to bother. Stuller claims they do not know
the contents.


Stuller does have the msda sheet on the J.S. brass. Please advise
and we will be able to send to you.
