Gallium + aluminum = bad time so just be careful when doing so, all.


Yes agree but MacBook Pro heatsinks are copper.


Sure, but much of the rest of the machine is aluminum, so the caution is warranted. The two metals don't like each other. https://www.youtube.com/watch?v=IZkzxWZETds


The problem is that they like each other too much. Liquid Gallium basically soaks into the Aluminum, and the Gallium-Aluminum alloy is very weak, at least at room temperature.
