Can unplated brass grow whiskers?

Are there any known conditions where unplated brass ever grows whiskers?
(Context is a spec clause chase.)

You would probably need to conduct a thorough literature search to know the answer. However, everything that I've read indicates that whiskers are a special problem of pure metals, and any alloying ingredients reduce the problem; considering the large amount of alloying material in brass, it sounds safe. Further, whiskers seem to be stress reduction mechanisms that mostly occur on electroplated coatings.
