The problem with this is the company has to somehow acquire the material, somehow managed to machine it to certain tolerance, and somehow make it perform better than what the abundance aluminum can do.
And even if they managed to do that, not everyone is willing to pay for it.
Though I’m not necessarily a manufacturer, at least I know there is a HUGE risk of going with strange materials, not to mention the time spent on designing, since the material is new you’ll also need to redesign and recalculate everything.
Aluminum alloy are the best because: they have great properties, relatively low priced, can be made into a near perfect circle by a well known method. Unless there is actual performance to be gained by using ‘boutique’ materials to justify the price, then it’s unlikely to be made. At best there might be some experienced modder who like trying out stuff.
