I have only glossed over this. I am not a metallurgist, I am a machinist. 30 years worth. I cut the stuff i dont investigate its properties. Nickle alloys are high heat application materials. Inconel 625 and 718, stellite, waspalloy and a few more . Not stainless steel or titanium. Nickle alloys are their own class of stupid high resistance to stupid high heat and toughness that make carbide cutters wear out quick.
This cant be about money. What fool looks to space to make a buck....not having a tractor beam you know?
This has got to be a bogus story. Good line for the layman though. However...If I were to choose a material to make the ultimate earth-shattering asteroid, guess what it would be?
A diamond?
Neutronium?
There must be a muzzie out there that needs outreach...................
