Strong thermal conductivity and more heat-resistant.Chromium zirconium copper is embedded in the nozzle, which has high thermal conductivity and high wear resistance, reducing oxidation reactions at high temperatures and achieving good printing results. Chamfered Design Each nozzle is designed with a chamfered design to provide less resistance and smoother appearance, avoiding clogging or adhesion issues. CHT nozzles can provide twice the flow rate of ordinary nozzles . You only need to replace one nozzle to achieve the effect of a volcanic nozzle, which increases the printing speed and is suitable for high-speed printers. High hardness and more wear-resistant Made of high-hardness steel, it is more wear-resistant after heat treatment and can print more consumables. High-hardness consumables can also be printed easily. Corrosion resistance, long service life, advanced heat treatment process, better corrosion resistance, extended nozzle service life Consumables: 1.75mm Specifications: 0.4mm Size: 6x13mm Applicable models: for CR-6 SE/Ender-3/Ender-3 pro/Ender-3 V2 for Ender-5/Ender-5 pro/Ender-5 plus/CR-10 Thread: M6 Colour:As Shown Material:Metal Package Contents: 1 x brass CHT nozzle 0.4mm 1 x Copper-plated CHT nozzle 0.4mm 1 x Hardened Steel CHT nozzle 0.4mm Only the above package content, other products are not included.
