thank you. this thread is extremely silly. Titanium has its uses, holding edges and making repetitive high-intertia impacts are not some of those uses.
Titanium is chiefly useful as a structural material, and you will have a much better idea of its properties if you think of it as "situational side-grade to aluminum" rather than "lighter steel". Titanium is constantly in vogue because you can make truthful claims about its properties that laymen will not understand are not necessarily important. That said, here are some other situationally useful metals that you can buzzword sci-fi vogue your brain on:
Beryllium Metal, Magnesium Metal, Niobium, Vanadium, Scandium (specifically aluminum-scandium alloys), Manganese, Samarium-Cobalt, Yttrium Optical Garnet, Palladium, Iridium, Osmium, Molybdenum
