if available at a good price, there's always something one can do with the stuff. brass can be troublesome, esp if it's cast. in sheet form, it should be ok to engrave. i have had little trouble working the stuff in sheet form. then again, i never knew specific alloy info.
I purchased this, found a metal fabrication shop to cut the 36x48 sheets into manageable pieces and tried it out. I am certainly no expert, but it seemed to cut okay. At least as good as the hobby shop brass I had been using. thanks for all of the replies.
