Fastest oxidizing meterials? that are cheap to deoxidizing?

[supak111]

I'm looking for some fast oxidizing materials that are cheap to deoxidize.

For example: For my experiment I could use aluminum since it oxidizes very fast, but "aluminum oxide" is pretty expensive to turn back to aluminum as far as I know.

What other material attracts oxygen and (oxidizes fast) BUT yet are pretty cheap/easy to deoxidize? There must me some material out there that we have found a cheap deoxidizing process for.Thanks for your help guys.

Define cheap and easy.

Well say to turn 1LB of the material back to NON oxidized state for less then $1 per 1LB. If it cost more then its just as expensive as using aluminum
