do you mean stuffables? because many of the things that strictly need bioferrite are good.
i would use it for gravship hulls because it has more health than steel, and it's not flammable.
also melee weapons and apparel made of bioferrite give a psychic sensitivity boost to the wearer. bioferrite longswords aren't the best dps but they might be best for your melee psycaster until you get a good persona weapon. bioferrite slave collars are good for psycasters too, they don't interfere with any armor.
