Features: Made of hardened steel and embedded chromium-zirconium copper, it has good thermal conductivity and high wear resistance, reducing the oxidation reaction of high-temperature wires and achieving good printing results. The tightly sealed anti-leakage material nozzle is connected via thread and in contact with the lower step of the thermal switch, reducing the risk of loosening and leakage. The detachable nozzle is easy to replace, and the thread surface is coated with adhesive to effectively prevent leakage of consumables. Heat up before replacing the nozzle. The embedded chromium-zirconium copper inner hole is embedded with chromium-zirconium copper, making the nozzle more wear-resistant, evenly heated, and the technical consumables fast and stable. Chamfer Design: Each nozzle has a chamfer design, which reduces resistance, is smooth, and avoids blockage or adhesion. Compatible with all 1.75mm consumables including PLA, ABS, PETG, PC, Nylon, etc. Specifications: Item: Hardened Steel Nozzle Type: 0.2mm/ 0.4mm/0.6mm/0.8mm Size: As pictures Material: Hardened Steel Color: As pictures Quantity: 1 pc Note: Due to lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
