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:

resistance of materials to attack by gallium

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.
