AS REPORTEDno primary record reached; this is what the reporting says
Available sources confirm that gallium causes liquid metal embrittlement in specific brass compositions such as beta-brass, but they do not establish that all forms of brass are affected.

## Question
I know that it corrodes copper, but does it do the same to all brass or bronze compositions?
## Answers
### Answer by Gowtham (score: 4 [ACCEPTED])
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.

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.
