I was questioning the use of brass for a bit but it seems that it was an effective armor and also quite expensive. Romans also used brass for coins, it seems.
Brass is generally a soft metal and work hardens fairly quick. Annealing brass is easy with propane but that is something the Romans probably didn't have. (I work with brass occasionally and it's an interesting metal.)
I'm not an expert on metals, history or Roman armor or anything, but this took me down an interesting path reading into Roman metallurgy and the history of brass. It's been around since at least 5000 BCE, interestingly enough. Huh.
