Features: Hardened steel and embedded chromiumzirconiumCopper, it has highthermal conductivity, wear resistance, and oxidation reaction at highTemperatures, achieving good printing results. Adopting highhardness steel, after heattreatment, it is more wear-resistant and can print more consumables. Highhardness consumables can also be easily printed. Adopting CNCprecision automatic lathe centering processing and embedded chromezirconium coppermaterial technology, ensuring that the input and output holes areconcentric, the nozzle is smooth and free of burrs, and the extrusion is faster and more uniform. The nozzle adopts a chamfered design, which reduces resistance and is smooth to avoid blockage or adhesion issue; Chromium zirconiumcopper is embedded in the inner hole, making the nozzle more wear-resistant, heating evenly, and extruding consumables quickly and stably; The tight fitting of the joint effectively prevents material leakage from the printing head. Compatiblewith 1.75mm consumables, includingPLA, ABS, PETG, TPUs, PC, PP, nylon etc. Specifications: Item: Hardened Steel Nozzle Type: 0.2mm/ 0.4mm/0.6mm/0.8mm/1.0mm/1.2mm Size: As Pictures Material: Hardened Steel Color: As Pictures Quantity: 1PC Note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
