As for a argument sake, I think the prostectic leg do contain enough iron to let Pyrraa deflect it. As what I know, screws and particular elements in mechanical prostethic can'/t and/or difficult to be made with other materials other then ferro materials. For example Kneecap prostetics where made of stainless-steel which often is magnetic. Titanium of now more used for it in my understanding, but that is in living tissue. Mechanical wise, titanium woulb be to hard and/or brittle for junctions and as for aluminium to soft. Iron/steel is a sweetspot for some part I guess
