The designation of "hard" with brasses has to do with the rolling/squeezing of the material. It has nothing to do with the alloy composition. Copper alloys can be work hardened: the more you roll it/work it the harder it gets. The ultimate end of hardness for brass is spring hard...

So it was not full hard brass?

From the text of Rick's post, it sounds like the material turned out to be copper.
