The impervious alloy is a substance from the Generation 1 continuity.

The impervious alloy is resistant to heat and radiation. It was developed by Dr. Mark Morgan and Gregory Swofford.

Fiction

The Transformers cartoon

Gregory Swofford and Jessica Morgan took out an experimental ship coated in their new alloy into the vicinity of an exploding star. Even after getting closer to save Optimus Prime from his doomed cruiser, their ship survived the supernova. Once back to Earth, their lab was attacked by the Terrorcons. Despite the valiant effort of the Technobots, the alloy was stolen by the Decepticon raiders. The Return of Optimus Prime, Part 1

Once Optimus Prime was revived, he led a team to Chaar to get the alloy back and use it to fight the Hate Plague. After a number of Autobots were infected, Optimus and Sky Lynx were able to recover the alloy. A Quintesson was able to coat Optimus Prime in it for his fight with Rodimus Prime to protect him from the plague's effects. The Return of Optimus Prime, Part 2

Notes

• The alloy is impervious to heat, yet can somehow be melted/dissolved to coat Optimus Prime for his battle with Rodimus Prime.
