In Terminator: The Sarah Connor Chronicles, thermite is used to destroy the endoskeletons of terminators. As the endos are made with coltan (which has a higher melting point than titanium), thermite is the only effective way to melt them down. The Vick Chamberlain Terminator (and presumably Rosie) were destroyed in this manner by Cameron. Cameron was almost melted by thermite after she was corrupted. The Bedell Terminator was destroyed with thermite by John Connor after being "killed" by Derek Reese.
