Rubidium is a metal, but it isn't considered to be malleable for two main reasons: first, it is not very hard; in fact you can cut it easily with a knife; second, it is so highly reactive that it would not be practical to try to shape it. Being an alkali metal in period 5, it is explosively reactive even with air.
