one of the main points behind a lightsaber is that it has no weight other than the hilt, and most materials provide little to no resistance to its cutting effects, until you get into special materials that mostly just don't cut easily. cortosis weave/ore/plates while fragile and worthless (or virtually so) for conventional armor, somehow disrupt the energy flow (if enough cortosis is present) which shuts the saber down, although if there is enough energy remaining in the cell it can usually just be reactivated.
beskar aka mandilorian iron is resistant to the cutting effects it doesn't STOP it completely, mind you but for the sake of an analogy 1 inch of mando steel is like cutting through a foot or so of normal steel (this is mostly a wag but its the principle) so if Jengo, had had a gorget of mando steel protecting his neck mace might not have decapped him so easily, My read is that jango didn't worry about it much because he felt, most jedi couldn't hit with the precision needed, they would either hit the shoulder, or helmet if they tried.....
songsteel from the wookipedia article is similar, and noted as being a complete pain to work, so I would guess its mostly a saber resistant alloy, functions as if there is a lot more material present than actually exists through techno babble ...
with that said it depends on what you mean by friction /traction if you grab a saber blade. can you block or parry? absolutely, can you grab their blade and hold it for a moment so that they have to take a moment to pull it back out of your grip? sure, can you "grab the blade and yank it out of their hand? I really don't think so, because the way I read it, much like ultrachrome most of the saber resistant alloys /materials basically just resist the cutting effect of a lightsabre.
at least that's my opinion.
