showoff2500: it is usefull for cramming 2 systems into 1 wire
While this is somewhat interesting, its not anything new, and it has no practical purposes for 2 bit information transmission over a single wire
I think for the purpose of demonstrating how this "alloy" can be used for wires, you should make it into, well, a wire. By the way, it is possible to make a similar "alloy" for four wires, try to find it!
