Durable: MK8 extruder nozzle is made of hardened tool steel, with good wear resistance, heat resistance and corrosion resistance, suitable compatible with 3D printing at high temperatures, and the solid structure makes it durable and can serve youGood percompatible withmance: The toughness and hardness of the extrusion nozzle of this 3D printer is impressive. It is not only suitable compatible with common 1.75mm 3D printer filaments, but also compatible with printing filaments such as carbon fiber and glass fiber.Impressive accuracy: The inner wall of the MK8 nozzle is smooth and free of burrs, and the viscosity coefficient is small. The diameter error of the extruder nozzle is less than 0.02 mm, providing you with accurate and smooth extrusionCompatibility: These high temperature tip wear-resistant nozzles are compatible with compatible with the MK8 hotend of the Creality 3D printer, compatible with compatible with Ender-2 / Ender-3 / Ender-3 pro/ Ender-5, and also compatible with compatible with Creality CR-10 all-metal hotend, Prusai 3 , Anet A8, Reprap, etc.Colour: Black + goldMaterial: hardened tool steel + brassPackage Contents:8 x 0.4mm MK8 hardened steel nozzle28 x 0.4mm brass nozzle3 x (0.2mm+0.3mm+0.5mm+0.6mm) brass nozzleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
