Feature: 1. Copper Alloy: Higher thermal conductivity ensures uniform heating of the nozzle and smoother extrusion. Improve the structural strength of layer-to-layer adhesion, which greatly levels up the printing quality. 2. Premium Material: Up to 500℃ high temperature resistance ensure fast heating of the high-temperature filaments and continuous printing. 3. Uniform Nickel Plating: Greatly reduce the adhesion of filaments to the nozzle and smoother extrusion. 4. Extensive Compatibility: 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. Compatible with a variety of Creality models, including CR-10 series, Ender-3 series and Ender-5 series. 5. What You Get: This Copper Alloy nozzle kit including 8pcs high quality nozzles, 0.25mm (1pc), 0.4mm (3pcs), 0.6mm (2pcs), 0.8mm (2pcs).
