This Heatbreak is improved with special Nano Coating called DLC, DLC Nano Coating not only has excellent wear resistance, but also has a very low friction coefficient and excellent corrosion resistance, with a generally smooth surface,better for filament feeding It is named "Bi-Metal Heatbreak" It has two components -Copper and Titanium TC4 with different thermal conductivity. Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction. And Can reach up to 500°C degree The inner wall of the titanium is very smooth Plus the DLC nano coating so that the filament can pass through very smoothly and stop clogging. And We use a special process to hold them firmly together. You don't need to worry about it being damaged. Compatible with Artillery Hornet, Genius,Genius Pro, Sidewinder SW X1 X2 3D Printer and Original Chimera Chimera+ Cyclops Cyclops Plus Muti color Hotend 3D Printer NOTE: We found that many customers do not know how to properly install the nozzle. Remember the core issues in the installation process. Just make sure your nozzle and HEAT BREAK front end are tight and sealed. Otherwise, the melted consumables will leak along the screw holes.
