• 【Compatible With Multiple FDM 3D Printers】: This nozzles kit is compatible with Elegoo Centauri Carbon/Centauri/CC2 3d printers, please confirm your 3D printer model before ordering.
• 【5PCS 3D Printer Extruder Nozzles Kit】: Input diameter is 1.75mm, output diameter is 0.4mm, included 5pcs hardened steel nozzles. Sufficient quantity and hardened steel material of hotend nozzles make it easy for you to change them in time for quality printing.
• 【High Precision Nozzles】: The nozzle set is made of high precision CNC machining, with better thermal conductivity and high hardness, smooth and burr-free inner wall, low viscosity coefficient, nozzle error less than 0.02mm, chamfered and rounded to reduce the resistance of the diamond angle to the filament, smoother feeding filament, not easy to clog, to provide you with precise and smooth extrusion printings.
• 【High Quality 3D Printer Parts & Accessories】: Made of high-quality hardened steel, which has a large weight, advanced heat treatment process, and better oxidation resistance, which extends the service life of the nozzle. The contact surface is flat, solving the problem of filament leakage and effectively preventing printing head leakage. Stable performance and durability. Compatible with most high-temperature and low-temperature printing filaments on the market.
• 【Corrosion Resistance】: The surface of the hardened steel nozzle has undergone special treatment (such as coating or passivation) to resist corrosive gases or material residues generated during the printing process, thereby extending its service life.
• 【Material Advantages】: The hardened steel nozzle, through heat treatment or alloying processes, enhances its hardness, resulting in a wear resistance that is 2-7 times greater than that of ordinary steel nozzles.
