They mention both high temperature durability and conductivity as positives. Not really the most important qualities in a bike frame to be fair.

I doubt it beats aluminium in cost, so it would need to significantly beat carbon in performance to make it worthwhile.

For a bicycle frame, we want an alloy that is relatively light and easy to weld. At no point is weldability considered, and it is not impossible that this alloy welds very poorly (losing its properties in the area thermally affected by welding, requires a very narrow energy range to weld properly).

The advantages of this alloy do not make it a better choice than special steels or titanium alloys when it comes to metallic materials.

There are few cyclists on Venus.

No, copper is stupidly expensive and steel/aluminium/magnesium are already very competitive. Also, wood is technically an option. It might compete with titanium frames (or carbon fiber frames) perhaps, but that's a niche market and I doubt it.

Well it's on par with stainless steel strength wise while being both more expensive and heaver. Presumably also much more prone to corrosion.

It would be a very expensive bicycle frame. That is for 100% certain ;)

If you don't mind it being heavier than a steel frame.
