More Info:
Higher Flow. Thanks to E3D’s unique high-flow internal geometry that increases surface area for better heat transfer, these nozzles significantly boost your setup's volumetric flow rate, allowing you to print faster!
Abrasion Resistance. With wear resistance far superior to any generic hardened steel nozzle, ObXidian is exceptionally hard, making it ideal for printing abrasive or filled polymers. This is accomplished by combining a tool steel insert with E3D’s custom E3DLC™ coating. This specially formulated coating also provides non-stick properties, significantly reducing plastic build-up around the nozzle
Drop-in upgrades. These nozzles maintain the exact same form factor as standard Prusa Nozzles; this means there is no need to adjust your pre-existing mount and fan duct setups.
Quick Nozzle Changing. Changing a nozzle on your Prusa printer has never been easier! Waste less time changing your nozzles and more time experimenting with different sizes and materials. 
Easy identification. Each Nozzle has its size engraved into it.
