It's not an unknown alloy.

I dug around a bit and it's a 3d layer printed nano-composite of very high purity bismuth and magnesium doped with some other trace elements and a crystal structure that they think indicates it was grown in a zero-G environment. Apparently even the wiring is baked in. I mean if we didn't know how processors were made, they would look like magic under the microscope as well. But I guess they genuinely don't understand how the layering was achieved.

What they say they don't know is how to manufacture it.
