Material: This nozzle is made of hardened steel, with good abrasion resistance, heat resistance, and corrosion resistance, sturdy construction makes it enough to you for a long time, suitable for 3D printing at high temperatures. High Speed: It's a special hardened steel design so the print head heats evenly. The interior of the nozzle is smooth without burry, which not only reduces air resistance and prevents the filament from jamming. Smooth Inside: Smooth inner wall without burr, minor viscosity coefficient, smoother tapping. smooth contact solves the problem of consumables leakage and effectively prevents printing head leakage. Support Filaments: The max temperature of the Hardened Steel nozzle is 500, it can be compatible with PLA, PETG, ABS, TPU, etc 1.75mm Filament. Suitability and Compatibility: Our hardened steel nozzle kits are compatible for 2/ 2 Neo/ 2 Pro/ 2 Plus/ Plus/ Max 3D printers. Please note:Slight color difference or difference in kind, does not affect the use, please do not mind, thank you!
