Answer:
I might be way off here but I guess you are talking about in relation to Damascus Steel? This is a form of steel made in Persia and north India and traded westwards. It was most often bought by Europeans in Damascus in modern day Syria so the name comes from there.

Damascus Brass by extension would be super pure strong brass from Damascus.

In short there isn't such a thing as "Damascus brass" in the same way as Steel.

However Brass objects made in such a way as to mimic the "watered" appearance of Damascus Steel might be named as such or indeed anything made in Syria of brass could be called such.
