Liquid Metal Embrittlement - Gallium vs. Aluminium

Bringing gallium and aluminium together has some interesting and occasionally rather explosive results, as Dan found out in this little tale from the prep room. Liquid metal embrittlement is a phenomenon where ductile metals, like aluminium, become brittle when exposed to certain liquid metals, like gallium. The mechanism is not chemical but physical, as the liquid nature of gallium allows it to infiltrate spaces within the aluminium structure.
