The metals you mentioned earlier appear to be borderline magical without some hard science behind them. Judging by what most other people have created, it would be plausible for a highly advanced civilization to have created the materials you mentioned, but even as genius of a man your character may be, it's just not very feasible.

To improve on this, I would really love it if you wrote up some background science explaining the unusual properties of the metals, and even some information about how they are made/what makes the production process so special.
