Chemistry - Does Gallium (liquid or solid) corrode all forms of brass?

Solution 1:

From here

Gallium is corrosive to all metals except tungsten and tantalum, which have a high resistance to corrosion.

Beta-Brass is embrittled by Gallium

Due to its highly reducing character it is highly corrosive material.

Solution 2:

I had looked at more direct sources from the Wikipedia link that was provided in the previous answer to this question. On page 99 of the 1954 version of "Liquid-Metals Handbook", there is a chart that might answer your question better:

The next two pages from the the same book gives more information about the other chemicals that leads me to believe that the Wikipedia article might be misquoting the information.
