New Copper Alloy and Hardened Steel Nozzle K1 Nozzle Kit Supporting High-Speed Printing Speed of 600mm/s for K1 / K1 Max/CR-M4 3D Printer Parts Suitable for Most of Filaments PLA/ABS / - Irfora, LAKUSOS7073

• Copper Alloy with High Thermal Conductivity High 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 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 reduce the adhesion of filaments to the nozzle and smoother extrusion. Copper alloy nozzle are suitable for most other FDM materials and PEEK, PEKK PEI, PSU, PPSU and other high temperature consumables. Hardened Steel Nozzle: High Hardness, More Wear-resistant and Service Life. Hardened Steel Resists, Corrosion for Service Life: Advanced heat process and better anti-oxidation are combined to prolong the service life of the nozzle. What you get: 8pcs nozzles of different sizes. 2 x 0.4mm Copper Alloy Nozzle, 1 x 0.6mm Copper Alloy Nozzle, 1 x 0.8mm Copper Alloy Nozzle, 2 x 0.4mm Hardened Steel Nozzle, 1 x 0.6mm Hardened Steel Nozzle.
