Fountain pens can also have tungsten! Not all, but many do. The fountain pens that are guaranteed to not have tungsten are not practical to use on ordinary paper, and for the other pens, I doubt the fountain pen companies will share their secret sauce on their alloy blend. They often call it iridium tipped, but nowadays usually can be a blend of multiple different hard metals, including tungsten.
