If that won't do, you should use the word "dynamic" somehow in your slogan, I think it would be good. Copper is solf and malleable and used as a thermal and electricity (energy!
) conductor. It's also used in a lot of different things, like coins, roofs, pots and pans, statues, piping, wires, and... well, lots of things. If that's not dynamic, I don't know what is!
