This replacement V6 nozzle for E3D hotends is made of hardened steel. Hardened steel nozzles are suitable for some highly specialised materials, where a standard brass nozzle is at risk of corrosion. The hardened nozzle provides the same performance as the brass edition, but has a longer delivery time than the standard brass version.
This nozzle has an opening of 0.8mm (marking #5) and is suitable for filament with a diameter of 1.75mm.
