Alinan 4pcs CR10 Bimetal Heatbreak, Upgrade Smooth All Metal Bimetal Copper Titanium Heatbreak High Temperature Throat for 3D Printer CR10 S4 S5 Ender 3 V2 Ender3 pro Ender 5 CS3 Hotend

★Made of all-metal material, precision-machined, the bowden tube will fit 1/3 inside this throat as normal, but no PTFE wear or burn. This heatbreak throat cut is smooth and flat without any burrs, could be seamlessly connected with nozzle, no risk of filament leakage.
★The part of connecting the heat sink is made of copper alloy, which with high heat conduction, could make filament cool down rapidly. The part of connecting the nozzle is made of titanium alloy, which has low heat conduction. No need to change any settings, it just keeps the filament from melting prior to getting to the extruder nozzle helping to prevent blocking.
★Total length is 27.5mm with M6 screw thread. The inner hole finish is 0.3 and the torque is more than 10kg, could print 1.75mm Filament fast and safely, like PLA TPU PETG etc.
★Compatible for 3D Printer Upgrade CR10 S4 S5 Ender 3 V2 Ender3 pro Ender 5 CS3 Hotends.
【Note】: please tighten the throat before tightening the nozzle, and tighten the nozzle again after heating to 280℃, be careful of burns.
