budullewraagh Posted May 4, 2005 Share Posted May 4, 2005 so you just want to corrode metals? HF, H2SO4, HNO3, HClO4, HMnO4 come to mind Link to comment Share on other sites More sharing options...

H2SO4 Posted May 5, 2005 Share Posted May 5, 2005 what is alpha iron. An isotope? But then it would be worth thousands. I dont know and i know its most likely not an isotope but ive never heard of gamma or alpha iron. Explain then we may be able to help you better.
