It combines the high thermal conductivity of copper alloys with the wear resistance of hardened steel, allowing you to easily print filaments filled with a variety of abrasive materials such as GF CF or luminous while maintaining flowrate and interlayer bond strength and surface quality.
The body of this nozzle has electroless nickel plate finish to prevent oxidation and increase surface hardness and inset the hardened steel

Works with Any Creality Printer which has Volcano Nozzle Similar to K1
