There is generally no need to make it supper light, or supper stiff or supper strong or supper low rotating inertia or supper anything.
It is one of those things that just has to be "good enough".
You can get there by changing the strength of the material used or the amount of material used. That is to say more weak material is just a good enough as less strong material.

In that case you might want to design so that thread failure happens in the cheap and easy to replace part, not the expensive and hard to replace part when that prybar is used to try to turn the wheel too far.
It just might be that the OP's client want's to ensure this happens by asking for an "inferior" material.
The OP needs to engage brain, not seek answers on the internet to poorly defined questions.
Better yet, have an actual discussion with the client, rather than trying to blindly convince the client that "our standard material is better, which is where the OP seems to want to go.
