I am using these for Carbon fiber, Wood, And Iron filament. I have had trouble with the abrasive filaments with .4 nozzles. I just recently went with the .6 nozzles and I am having much better luck with nozzle not clogging. could be the filament as well.

Any nozzles with the correct thread will work. you may have to tear apart your heatblock/heatbreak. (you should probably do that anyways as they are generally not assembled properly from factory. tighten down your heatbreak to the hot end and set the set screw and screw in your nozzle last. you do not want the nozzle to bottom out to the threads you want the nozzle to seat into the heatbreak to create a seal otherwise you will have nozzle leakage above the heat block or at the nozzle threads
