What is inside of the REVO shaft?

Depending on the composite make up, but 0.81mm is actually quite a substantial wall section.

It’s a ferromagnetic metal. Not aluminum.

What is the significance as pool cue shafts go of this metal being ferromagnetic?

Maybe they are talking about its ferromagnetic properties, or the lack of a magnetic field?

Steel has many different compositions, and each have different ferromagnetic properties.

Unless you are trying to create a magnet, most steels are categorized for their resistance to becoming magnetic when cold worked.

For instance, stainless steel 304 does not have as good a resistance to becoming magnetized during cold work as stainless steel 316.

I am just curious.
