The Heatbtreak is made from two components, Copper and Titanium TC4. Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction. The inner wall of the titanium is very smooth so that the filament can pass through and reduce clogging.Heater block and 0.4mm nozzle are made from Premium Copper material with Nickel plating Rated to 500 for even the most demanding tasks,Compatible with all filaments,from basic PLAs to custom medical-grade PAEKs. Non- stick, high performance, Excellent precision production,make sure the nozzle is smooth without burrs. the filament running more smoother.For -10/-10S Series, for -10 MINI, for -20/-20 Pro, for 2/ 3, for 3 Pro, for 5 3D Printer.Using the top screw of the heating block to fix the heat sink, it is more convenient to replace the nozzle with one hand, and it is also more convenient to replace the heating rod of the temperature measuring rod. The hot end is mainly composed of electroplated copper material, which has the advantages of faster heating and better heat dissipation.Compatible with all filaments: including PLA, ABS, PEG, TPU, PP, PC. Nylon, , PEL,and composites containing abrasive additives such as carbon fiber, steel, wood, boron carbide, tungsten and pigments.Colour:B:RedMaterial:MetalPackage Contents:1 * for -10 Extrusion Head KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
