Creality Upgraded K1 Nozzle Kit, Hardened Steel Nozzle & High-end Hardened Copper Alloy, High-Speed & High-Temperature (

● Compatible model: K1, K1 Max, CR-M4, CR-10SE, Ender-3 V3 KE

● Copper Alloy with High Thermal Conductivity High Flow for High-Speed Printing: The thermal conductivity of copper alloy is as high as 330W/m·k, ensuring that the nozzle is heated more evenly. The volume is twice as large as ordinary nozzles, supporting high-speed printing speed of 600mm/s. 

● Uniform Nickel Plating, Smoother Extrusion: The nickel-plated layer on the surface greatly reduces the adhesion of filaments to the nozzle and smoother extrusion. *Applicable to most FDM materials such as PLA, ABS, PETG, TPE, TPU, PC, etc., And PEEK, PEKK, PEI, PSU, PPSU and other high temperature filaments.

● Hardened Steel Resists Corrosion for Longer Service Life: Advanced heat treatment process and better anti-oxidation are combined to prolong the service life of the nozzle *Applicable to most FDM materials such as PLA, ABS, PETG, TPE, TPU, PC, etc., and composite filaments with grinding additives such as carbon fiber, glass fiber, steel, wood, boron carbide, tungsten, phosphorescent pigments, etc.

● Premium Materials Handle High Temperature Filaments: Ensure fast heating of the high-temperature filaments and continuous printing * Copper alloy high temperature resistance up to 500°, hardened steel high temperature resistance up to 450°.

● Hardened Steel Nozzle High Hardness, More Wear-resistant and Longer Service Life.
