Features: 1.APPLICABLE MODELS: V6 hardened steel black nozzle for 3D printers such as for CR 10 Anet8 and compatible with all 1.75 mm PLA ABS 3D printers. 2.HARDENED STEEL: Made of hardened steel material, high strength, high thermal strength, can work for a long time under the temperature of 450?500. Hardened steel is at low and ultra low temperatures, but still maintains its mechanical properties. 3.DURABLE DESIGN: Harder, more wear resistant than brass nozzles for longer service life. Features excellent durability for extended use to ensure long lasting print performance. 4.CNC MANUFACTURING: Made with CNC precise automatic lathe to ensure the input and output holes are concentric. Unique molding technology ensures that the inside of the nozzle is smooth and burr free, which not only reduces resistance and avoids filament clogging, but also makes the filament run smoother. 5.ROUNDED APERTURE: The chamfered cutting aperture is rounded, which reduces the resistance of the edges to the consumables and ensures smooth feeding to prevent clogging. specification:Item Type: V6 Hardened Steel Nozzle Material: Metal Compatible Models: for CR 10 Anet8 PackageList:4 x V6HardenedSteelNozzle NoteAll data are measured manually, and there are certain errors in the measurement results.
