6PCS Official K1 Nozzle Kit Plated Copper/Hardened Steel Extruder Nozzles 0.4mm 0.6mm 0.8mm High Flow High Temperature Resistance for K1 / K1 Max/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 450C 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 extrusionCompatible with K1 K1 Max CR-M4. Can print most FDM materials such as ABS PLA PETG TPE TPU PC etc and composite filaments.
