6PCS Official K1 Max Hotend Nozzle Kit Plated Copper/Hardened Steel Extruder Nozzles 0.4mm 0.6 0.8 High Flow High Temperature for K1 / K1 Max/Ender 3 V3 KE / CR10 SE/CR M4 3D Printer Accessories
Copper material nozzle has good thermal conductivity and high strength and high temperature which can reach up to 500C degree, while hardened steel material with hardened treatment, better wear-resistance, higher temperature up to 450°C, longer lifetime.
Roughness Ra<0.4, Smoother inner wall, no clogging, Enhances the fluidity of the filament, brings super-smooth extrusion, impeccable precision orifice, no burr in the orifice, and smoother feeding.
High hardness and wear resistance, better anti-oxidation, it greatly reduces the adhesion between filament and the nozzle which results in more than smooth extrusion
Compatible with K1,K1 Max, CR-M4, Ender 3 V3 KE and CR-10 SE 3D printer . Can print most FDM materials such as ABS, PLA, PETG, TPE, TPU PC, etc,and composite filaments.
