Alloy 910 filament with TAZ 5.

I have TAZ 5 Printer with the standard Single Extruder Tool Head v2 (Nozzle diameter=0.35mm). I want to try printing Alloy 910 filament on my machine. I see the profile posted for this filament is for 0.5 mm Nozzle diameter.
Do I need to change the tool head to be able to print Alloy 910 filament on my machine? if yes, is it Flexystruder Tool Head?

Nah, you should be fine, just change the nozzle diameter in your slicing engine before you go to print. Your mileage may vary.
