After attending a "green" seminar in chicago I got to thinking how we can lower greenhouse emissions and save energy. We all know that cars work by lighting gas and using the force created to power the car. I was wondering if there any easily obtainaable chemicals that cause the same effect as lighting gas?

I need to know how the following pure elements are ranked in terms of their malleability:

Iron
Cobalt
Nickel
Copper
Zinc

This is for a geocaching puzzle that I'm working on. I know how some of them are ranked already, but I want to double-check my answers to this as well. Thanks in advance.
