Ujjdwiurgh All-Metal Bi-Metal V6-TCrazy Heatbreak Titanium & Copper 3D Printer Nozzle Bimetal Throat for 1.75mm V6 Hotend Heater

The inner wall of the tube reaches 0.4um, which is very smooth, so the filament can pass through and reduce clogging. It is recommended that the return distance of the silk is set between 1-5 mm, and the direct drive printing effect is best. This product is composed of two metals: titanium and copper. Titanium reduces the upward conduction of heat at the heating position, and uses copper to dissipate heat to accelerate heat conduction. Performance exceeds for thermal fracture. The size is 1.5mm longer than the original v6 radiator, so it can be directly installed on the v6 radiator to make your V6 hot end perfect. Can be used for Windproof and Aero.
