E3D Nozzle ObXidian 1,75mm

This is the original, not a china copy. 

ObXidian 

With a wear resistance that is orders of magnitude higher than any other E3D nozzle, ObXidian is really hard. Several orders of magnitude harder than Nozzle X and any other generic hardened steel nozzle. 

This is achieved by pairing a tool steel insert with our new E3DLC™ coating. This specially formulated coating also embeds non-stick properties into the Nozzle itself. Meaning considerably less plastic build-up around the Nozzle.
